Chemistry changing the world to create a better future
These practical applications of Chemistry are part of the relevant and practically applicable research Prof André Roodt (far left) and his research group are involved in. With him are Dr Ebrahiem Botha, Post-doctoral fellow; Pheelo Nkoe, PhD student; Shaun Redgard, MSc student; and Dr Orbett Alexander, Post-doctoral fellow

Some people have a gift for explaining the most complex concepts in a way anyone could understand. Combine this gift with passion, energy, and enthusiasm, and you are close to describing a meeting with Prof André Roodt

Prof Roodt not only teaches Chemistry, he lives it. He has published more than 320 papers, lectured internationally more than 100 times, and has guided 35 PhD and 48 MSc students to complete their degrees. These figures are likely to conjure up visions of a dusty academic working on pie-in-the-sky theories. 

Adding value

Within minutes you are made aware of the fact that Chemistry is not only a subject confined to classrooms and labs. It is a means of changing the world through research to create a better future. In academic terms, Prof Roodt and his team are involved in ‘Homegeneous Catalysis’, ‘Radiopharmacy: Theranostics’, ‘Metal Benefication’, and ‘Conversion of carbon dioxide and water’. And just when you start to remember how terrifying high-school Chemistry was, Prof Roodt explains the practical nature of what they are doing.

Few of us are aware of the exact processes that produce fuel for our cars, although we probably know that these processes have side effects which are usually detrimental to the environment; but what if the by-products of these processes can be turned into speciality chemicals which could add value in different ways?

Ever wondered how medication know where to go in your body? Well – just imagine highly specialised (clever) pharmaceutical agents giving off their own ‘light’, knowing exactly where to go, showing you where they are going, and knowing what to do in order to provide information and interact with specific cells in your body to assist in healing cells and fighting disease. Exciting.

Passionate people

But, as they say in the ads, that is not all; imagine better ways to generate power, using the natural processes in plants to increase natural oxygen where needed, and to be able to change oxygen levels in the environment.

These practical applications of Chemistry are part of the relevant and practically applicable research Prof Roodt and his research group are involved in.

When you leave Prof Roodt’s office, you realise that this is what the UFS is all about: Global impact. World-class research. Passionate people. And seizing the opportunity to create the future.

Champagne and cancer have more in common than you might think

No, a glass of champagne will not cure cancer....

…But they have more in common than you might think.

Researchers from the Departments of Microbial Biochemical and Food Biotechnology, Physics and the Centre for Microscopy at the University of the Free State in South Africa were recently exploring the properties of yeast cells in wine and food to find out more of how yeast was able to manufacture the gas that caused bread to rise, champagne to fizz and traditional beer to foam. And the discovery they made is a breakthrough that may have enormous implications for the treatment of diseases in humans.

The team discovered that they could slice open cells with argon gas particles, and look inside. They were surprised to find a maze of tiny passages like gas chambers that allowed each cell to ‘breathe.’ It is this tiny set of ‘lungs’ that puts the bubbles in your bubbly and the bounce in your bread.

But it was the technique that the researchers used to open up the cells that caught the attention of the scientists at the Mayo Clinic (Tumor Angiogenesis and Vascular Biology Research Centre) in the US.

Using this technology, they ultimately aim to peer inside cells taken from a cancer patient to see how treatment was progressing. In this way they would be able to assist the Mayo team to target treatments more effectively, reduce dosages in order to make treatment gentler on the patient, and have an accurate view of how the cancer was being eliminated.

“Yes, we are working with the Mayo Clinic,” said Profes Lodewyk Kock from the Microbial, Biochemical and Food Biotechnology Department at the UFS.

“This technique we developed has enormous potential for cell research, whether it is for cancer treatment or any other investigation into the working of cells. Through nanotechnology, and our own invention called Auger-architectomics, we are able to see where no-one has been able to see before.”

The team of Prof Kock including Dr Chantel Swart, Kumisho Dithebe, Prof Hendrik Swart (Physics, UFS) and Prof Pieter van Wyk (Centre for Microscopy, UFS) unlocked the ‘missing link’ that explains the existence of bubbles inside yeasts, and incidentally have created a possible technique for tracking drug and chemotherapy treatment in human cells.

Their work has been published recently in FEMS Yeast Research, the leading international journal on yeast research. In addition, their discovery has been selected for display on the cover page of all 2013 issues of this journal.

One can most certainly raise a glass of champagne to celebrate that!
