Fletcher Hiten, Chief Bioanalyst at FARMOVS, next to Aurora.

The Bioanalytical Services Division (BASD) at FARMOVS comprises a group of skilled and passionate scientists involved in the quantification of drugs, metabolites, and biomarkers in various biological matrices. One of their Analytical Science experts, Fletcher Hiten, explains what sets their team apart from the rest.

“Over the past 47 years, we have developed almost 600 validated assay methods. Most of these methods are for the analysis of ‘small’ molecules using chromatographic techniques such as LC-MS/MS, GC-MS, and HPLC, although LC-MS/MS is the technique of choice. New bioanalytical assays are continuously being development and validated in adherence to international regulatory guidelines set by the US-FDA and European Medicines Agency (EMA),” says Hiten.

“Recently, we decided to enhance our capabilities by recruiting exceptional talent. The newest member of the FARMOVS team is Aurora, a SCIEX Triple Quad™ 7500 LC-MS/MS mass analyser. Aurora is Latin for ‘dawn’: the beginning of a new era, especially one considered favourable. The SCIEX 7500 is currently marketed as the most sensitive triple quadrupole mass spectrometer available, allowing for sub-picogram/ml quantification. This means that Aurora will set FARMOVS apart from other clinical research organisations (CROs), creating an exciting and favourable landscape for clients to explore new partners in research.” 

Hiten stated: “If there was ever a time to move your next study to FARMOVS, it is now. To have Aurora on our team has many advantages, given that our clients can access unprecedented analytical sensitivity, which enables the quantification of pharmacokinetic (PK) profiles of drugs that have very low systemic absorption. These include predominantly local acting drugs, such as plasma concentrations of respiratory drugs (e.g., tiotropium and ipratropium), topically applied creams and ointments, and ophthalmology drops with ultra-sensitivity.”

“In addition, the quantification of drugs in low-volume matrices will also be exponentially enhanced, enabling the quantification of body fluids, where only a few microlitres can be collected, for example vaginal fluid, dried blood spots, cerebrospinal fluid, aqueous humour, synovial fluid, and epidermal micro-dialysis lysate – to name a few. The quantification of absorbed exogenous drugs into tissue, like vaginal biopsies and hair follicles, is also possible,” added Hiten. 

“And finally, multiple analyte analysis. In this case, the collected blood sample needs to be split into multiple aliquots for analysis, for example drug-drug interaction (DDI) studies with the Basel cocktail. The smaller sample volumes will allow more frequent sampling to be feasible and thus more accurate DDI interpretation,” Hiten explains.

“As a bio-analyst, one is seldom surprised. However, Aurora has already opened doors to new frontiers for our entire team and we cannot wait to do some more exploration,” says Hiten.

Tiny microbes may solve large problems of water contamination, says Prof Esta van Heerden

Small solutions for big problems

According to Prof Esta van Heerden, professor in the Department of Microbial, Biochemical and Food Biotechnology at the University of the Free State (UFS), this might hold some truth in current terms of water treatment strategies for waste and industrial effluents.

“There is little doubt in popular literature that eminent water crises are looming, not only with respect to the supply, but quality and effectiveness of various treatment options as well. The UFS’s Department of Microbial, Biochemical and Food Biotechnology is partnering with the Technology Innovation Agency to evaluate water treatment technologies that are applied worldwide and to extend these new or adapted options to innovative and interested clients in South Africa,” says Prof Van Heerden.

“The research focuses on using extreme microbes to tackle big contaminations and the results are amazing,” says Prof Van Heerden.

These microbes are fast becoming the stars on sites and developing these exciting systems allows for greener treatment options. It is fascinating that they can deal with metals, including chromium and uranium, cyanide, petroleum and diesel.

Of utmost importance is the development of a treatment for acid mine drainage.

“Interests have been overwhelming and thus far partners have allowed pilot scale development on their sites with very promising results. These initiatives are driven by responsible partners who strive to be innovative and develop sustainable technologies for good quality water that can be released in the environment,” Prof Van Heerden says.

The research group has set up a pipeline to serve the water communities’ needs. It provides an accessible toolkit for water analysis. A tailor-made treatment option is also developed and showcased in the laboratories. It has the added benefit that Geosyntec Consultants, USA, will ensure faster roll-out by sharing their vast experience on any related aspects.
