The Women Shaping Science

Email: kyle.martin@media24.com

As South Africa prepares to commemorate National Women's Day on 9 August, it is fitting to reflect on the vital contributions women make in our laboratories—the unsung heroes advancing scientific discovery, ensuring quality control, and developing innovations that transform industries and save lives.

Yet the numbers tell a sobering story. According to Statistics South Africa, women comprise just 10.6% of technician roles across the country, whilst women represent only 23% of all STEM occupations in South Africa. Globally, the picture is similarly challenging: UNESCO's 2026 R&D Data Release reveals that women account for just 31.4% of researchers worldwide, with Sub-Saharan Africa at 32%—marginally above the global average but far from parity.

These statistics underscore a persistent 'leaky pipeline' phenomenon, where women enter STEM education in significant numbers but face barriers to professional advancement. In South Africa's chemical industry—a sector heavily reliant on laboratory expertise—women comprise approximately 35% of the workforce, with technicians and associate professionals representing the largest occupational group at 21% of sector employees. But statistics alone cannot capture the transformative impact of women in laboratory science. From microbiologists ensuring food safety to virologists tracking disease outbreaks, from analytical chemists developing sustainable materials to clinical laboratory scientists diagnosing illness, women are driving progress across every discipline represented in these pages.

This edition celebrates their achievements whilst acknowledging the work still required to achieve true representation. As we feature innovations from women engineers solving Africa's most pressing challenges, we recognise that laboratories need diverse perspectives to ask better questions, design inclusive solutions, and serve all communities effectively.

National Women's Day reminds us that progress requires collective action. For laboratory suppliers, educators, employers, and policymakers reading this publication: the future of analytical science depends on creating pathways for women to enter, remain, and lead in laboratory environments.

Yours sincerely Varushka

Milestone duoPUR and the Control of Analytical Blank

Sub-boiling acid purification for reliable trace and ultra-trace elemental analysis

In elemental analysis, reliable results at trace and ultra-trace levels depend not only on instrumentation, but on controlling sources of contamination. Among these, reagent purity is a key contributor to the analytical blank. The duoPUR acid purification system addresses this by enabling laboratories to produce high-purity acids within their own workflow.

Sub-boiling distillation for high-purity acid production

The duoPUR system is based on subboiling distillation, a recognised technique for acid purification. Unlike conventional distillation, which relies on vigorous boiling and can introduce aerosolised contaminants, sub-boiling technology gently vaporises the surface of the liquid using controlled infrared heating. This process minimises the formation of droplets and helps prevent re-contamination of the distillate, supporting the production of high-purity acids.

On-demand purification within the analytical workflow

By enabling on-demand purification, the duoPUR system allows laboratories to manage reagent quality more directly. Common acids used in elemental analysis, such as nitric acid and hydrochloric acid, can be purified as required, reducing reliance on externally supplied highpurity reagents. In addition, the ability to purify

reagent-grade acids supports more efficient use of laboratory resources. High-purity acids can be prepared as needed, supporting continuity of analysis while reducing dependence on prepurified acids.

The use of duoPUR supports a controlled approach to reagent preparation within the analytical workflow, particularly in applications where low detection limits and reproducibility are required.

The Milestone duoPUR quartz acid purification system enables laboratories to

and ultra-trace elemental analysis.

Green Microextraction Method Advances Therapeutic Drug Monitoring for Cardiac Patients

Researchers develop a validated DLLME-LC-MS/MS method for sotalol quantification in human plasma, reducing solvent use and improving extraction efficiency

Sotalol hydrochloride, a class III antiarrhythmic agent used for managing ventricular arrhythmias and atrial fibrillation, has a narrow therapeutic window that makes therapeutic drug monitoring essential. However, existing analytical methods often require large plasma volumes, hazardous organic solvents, and time-consuming sample preparation procedures.

A greener approach to sample preparation

Researchers have developed an LC-MS/MS method coupled with central composite design (CCD)-optimised dispersive liquidliquid microextraction (DLLME) for sotalol quantification in human plasma. DLLME uses minimal organic solvent, offering rapid extraction with high efficiency. The CCD approach systematically evaluated four parameters — disperser solvent volume, extraction solvent volume, sample pH, and centrifugation time — identifying extraction solvent volume, pH, and disperser volume as the dominant factors governing extraction efficiency.

Validated performance and sustainability

The optimised method was validated according to ICH M10 guidelines and applied to a pharmacokinetic study, producing results broadly consistent with published literature values.

Ethyl acetate served as the extraction solvent and ethanol was used for stock solutions, selected as a greener alternative to methanol.

Multi-metric sustainability assessment using tools including AGSA-prep, BAGI, and WECA demonstrated improved environmental performance relative to conventional extraction approaches such as solid-phase extraction and protein precipitation.

The study highlights DLLME's potential as a simple, cost-effective, and environmentally conscious sample preparation technique for bioanalytical applications, supporting the growing emphasis on green analytical chemistry in therapeutic drug monitoring.

FORENSIC TESTING

LC-MS solutions for forensic toxicology

Rapid Identification of Unknown Materials with Handheld Raman Technology

The MIRA XTR delivers in-field molecular identification of narcotics, explosives, and hazardous chemicals — in seconds

Forensic analysis often takes place under pressure, where rapid and accurate identification of unknown substances is critical to ensuring both safety and effective decision-making. Whether dealing with suspected narcotics, explosives, or hazardous chemicals, the ability to analyse materials directly at the point of contact has become increasingly important in modern forensic workflows.

Handheld Raman spectroscopy has emerged as a powerful tool in this context. By providing molecular "fingerprint" identification of substances, Raman techniques enable non-destructive analysis of solids, liquids, and powders without the need for sample preparation. This makes the technology particularly suitable for field-based forensic applications, where speed and reliability are essential.

Actionable results within seconds

The MIRA XTR handheld Raman analyser is

designed specifically to address these challenges. It enables rapid, in-field identification of unknown materials, delivering actionable results within seconds to support first responders and forensic professionals in critical situations.

known materials, even in complex or contaminated samples. Advanced algorithms further support analysis by mitigating fluorescence effects, enabling detection of substances that are typically difficult to analyse using conventional Raman systems.

New JRC-OECD Guidance Advances Safety Testing of Manufactured Nanomaterials

Updated 2025 guidance on sample

preparation and dosimetry reflects a decade of new knowledge, alongside certified reference materials to support regulatory compliance

The European Commission's Joint Research Centre (JRC) and the OECD have published updated guidance on sample preparation and dosimetry for the safety testing of manufactured nanomaterials. The 2025 edition reflects new knowledge accumulated since 2012 and covers general principles, dosimetry, and sample preparation for regulatory safety testing.

Sample preparation as the foundation of reproducible testing

Sample preparation is fundamental to nanomaterial testing, as it is the initial step for applying any testing protocol and achieving reproducible results. The unique physical and chemical properties of nanomaterials require specialised procedures to identify adverse effects and ensure safety for humans and the environment.

Progress and ongoing challenges after 25 years

The guidance update comes alongside a JRC-OECD review analysing 25 years of

nanotechnology research and regulation. The review identified ongoing challenges, including the lack of a unified regulatory definition, applicable test methods for physical and chemical characterisation, exposure assessment and modelling, and the quantification of nanomaterials in complex media.

Progress has been made, but areas needing further attention include alternative test methods, reference nanomaterials, and FAIR (findable, accessible, interoperable, and re-usable) data.

New

reference materials and alternative

testing

The JRC has also developed two new certified reference materials to support implementation of the European Commission's recommendation on a nanomaterial definition, helping laboratories reliably identify and measure nanomaterials in regulatory contexts.

Scientists emphasise the need to further explore alternative test methods,

such as in vitro testing and QSARs, to reduce reliance on animal testing and provide more efficient safety assessments.

The JRC's Nanobiotechnology Laboratory remains available to researchers and industries for nanomaterial, nanomedicine, and micro(nano)plastics research.

interactions, where small changes can influence performance. Electrochemical measurements enable in-situ monitoring of adsorption and kinetic processes, providing insight into system behaviour at the interface. By enabling reproducible electrochemical measurements, systems such as VIONIC support the study of processes occurring at small scales. As nanotechnology applications continue to evolve, electrochemical characterisation remains an important tool for understanding functional behaviour and supporting the development of new materials and sensor technologies.

The $29 million renovation was supported by the Provost's Office, the Vice Provost and Dean of Research, the School of Engineering, the School of Humanities and Sciences, and the Doerr School of Sustainability. Construction began in April 2024 and concluded in October 2025, with tool installation and commissioning following in early 2026.

Leadership and operational readiness

The Deep Lab is directed by Yuri Suzuki, the Stanley G. Wojcicki Professor of Applied Physics, who also leads the combined nano@ stanford unit. By consolidating nanofabrication and nanocharacterisation capabilities under a single organisation, Stanford aims to streamline access for researchers across disciplines.

Did you know?

The Deep Lab sits three stories below Stanford's engineering quad in a former physics facility — the underground location is essential because even subtle vibrations from surface activity can disrupt high-resolution electron microscopy and nanoscale measurements.

Super-Resolution Microscopy Reveals How Bacteria Degrade Biomass With Enzyme Complexes

Machine-learning-guided imaging of cellulosomes on Clostridium thermocellum opens new possibilities for consolidated bioprocessing of biofuels and biochemicals

Researchers at the National Laboratory of the Rockies (NLR) have used super-resolution microscopy combined with machine learning to produce the first real-time, quantitative picture of how bacteria degrade biomass using enzyme complexes known as cellulosomes.

A rare and powerful biomass degrader

Cellulosomes are large protein structures packed with dozens of enzymes, found on the surface of certain bacteria.

Only about 10 to 20 microbes have been identified with cellulosomes, making them a rare biomass deconstruction mechanism in nature. Clostridium thermocellum, the subject of the study, is considered the most efficient biomass degrader identified to date.

Machine-learning-guided imaging at the nanoscale

The research team, led by senior researcher John Yarbrough and group manager Yannick Bomble, captured more than 15 000 images of bacterial samples using a super-resolution

microscopy setup capable of resolving objects barely 30nm apart. An unsupervised machine-learning clustering algorithm was then applied to analyse the location and movement of cellulosomes across the bacterial surface.

The results revealed that cellulosomes are significantly more abundant on plant biomass than on the bacteria themselves toward the end of the bacterial life cycle. The team observed that cellulosome clusters became enriched at the cell surfaces in direct contact with biomass, and that they dynamically redistributed as biomass deconstruction progressed.

Towards consolidated bioprocessing

The quantitative imaging approach provides a statistical basis for comparing results as researchers genetically modify cellulosomes, supporting the development of consolidated bioprocessing — a method where biomass deconstruction and conversion occur in a single step, without the need for costly pretreatment or added enzymes.

Researchers Create World's First Synthetic Cell Capable of Growth and Division

SpudCell, built from non-living chemical components, marks a major milestone in synthetic biology with potential applications in drug synthesis and environmental remediation

Researchers at the University of Minnesota, led by synthetic biologist Kate Adamala, have announced the creation of SpudCell — the first synthetic cell built from scratch that exhibits a complete life cycle, including growth, DNA replication, and division.

Built from non-living components

The cell was constructed piece by piece from non-living chemical components, featuring a fatty membrane, a 90 kilobase genome, and 36 genes. Unlike previous synthetic constructs, SpudCell can perform essential cellular functions including resource acquisition, growth, genome replication, and division. The researchers released their data and methods via a preprint on bioRxiv on 1 July 2026.

A proof of concept, not yet alive

Whilst the creation represents a significant proof of concept, it is not considered alive by biological definitions, as it cannot survive without constant external support

such as deliveries of food and ribosomes.

Nevertheless, the breakthrough marks a major step towards engineering fully autonomous

synthetic cells. The research team, which includes Drew Endy, Jan Jedryszek, and Chris Raggio, has founded a public-benefit

institution called Biotic. The organisation aims to make the synthetic cell technology available to other researchers as an opensource standard for synthetic biology — similar to an operating system like Linux — with the eventual goal of facilitating applications such as plastic production, drug synthesis, and environmental remediation.

Building on incremental advances

The development follows a series of incremental advancements in the field. In July 2025, researchers at the Institute for Bioengineering of Catalonia developed a minimal artificial cell capable of chemical navigation, whilst scientists at the University of California San Diego incorporated metabolic activity into synthetic cell membranes. In May 2026, researchers at the University of Michigan and the University of Chicago used tardigrade proteins to improve synthetic cell durability under stress.
