South Campus: Social Responsibility Project team with Free State Department of Health nurses during the lunch of the campus’ COVID-19 pop-up vaccination site.

On Monday 27 September 2021, the University of the Free State, Provincial Department of Health and Department of Education launched a pop-up vaccination site at the South Campus bringing much-needed services closer to communities in the fight to end the COVID-19 pandemic.

Thandeka Mosholi, Head of Social Responsibility, Enterprise and Community Engagement, South Campus says, “We are next to the Mangaung community and bringing these services we encourage not only UFS staff and students but the surrounding communities to vaccinate for COVID-19. The institution and stakeholders are saying it is everyone’s responsibility for their health.”

She says, “If vaccination is recommended and we are told that it is safe, we encourage everyone including the youth to preserve our health and vaccinate.”

Representing the Department of Health, Papi Mokhele, Professional Pharmacist, says, “The initiative is aimed at reaching out to as many people to be vaccinated.”

He says, “At the moment the facility administers only the Pfizer vaccination and, as recommended by the National Government, we want to reach herd immunity – about 70% of the population – so that businesses, sporting facilities and many others can open and get our life back to normal.”

Other facilities the Department of Health has recently opened include the SABC Hoffman Square, Majakathata Taxi Rank, MUCCPP Health Centre in Phelindaba, Puma Garage in Bergman and Mangaung Outdoor Centre.

On partnering with the UFS, Mokhele says, “The COVID-19 vaccines have been put through clinical processes and quality assurance tests. They have also been approved by the South African Medicine Control Council and we call on the UFS community, especially students, to register and vaccinate.”

Coretha van den Heever, Teacher Trainer in the Social Responsibility Project, was recently vaccinated for the pandemic and says, “Let us protect ourselves and other people and not be the spreaders of the virus.”

She says, “People must make use of the facility; the UFS and government have brought the solution closer so that communities will not have to spend a lot of money travelling to get help.”

The vaccination centre will operate from Monday to Friday from 9:00 to 16:00.

Nanotechnology breakthrough at UFS
2010-08-19

 Ph.D students, Chantel Swart and Ntsoaki Leeuw


Scientists at the University of the Free State (UFS) made an important breakthrough in the use of nanotechnology in medical and biological research. The UFS team’s research has been accepted for publication by the internationally accredited Canadian Journal of Microbiology.

The UFS study dissected yeast cells exposed to over-used cooking oil by peeling microscopically thin layers off the yeast cells through the use of nanotechnology.

The yeast cells were enlarged thousands of times to study what was going on inside the cells, whilst at the same time establishing the chemical elements the cells are composed of. This was done by making microscopically small surgical incisions into the cell walls.

This groundbreaking research opens up a host of new uses for nanotechnology, as it was the first study ever in which biological cells were surgically manipulated and at the same time elemental analysis performed through nanotechnology. According to Prof. Lodewyk Kock, head of the Division Lipid Biotechnology at the UFS, the study has far reaching implications for biological and medical research.

The research was the result of collaboration between the Department of Microbial, Biochemical and Food Biotechnology, the Department of Physics (under the leadership of Prof. Hendrik Swart) and the Centre for Microscopy (under the leadership of Prof.Pieter van Wyk).

Two Ph.D. students, Chantel Swart and Ntsoaki Leeuw, overseen by professors Kock and Van Wyk, managed to successfully prepare yeast that was exposed to over-used cooking oil (used for deep frying of food) for this first ever method of nanotechnological research.

According to Prof. Kock, a single yeast cell is approximately 5 micrometres long. “A micrometre is one millionth of a metre – in laymen’s terms, even less than the diameter of a single hair – and completely invisible to the human eye.”

Through the use of nanotechnology, the chemical composition of the surface of the yeast cells could be established by making a surgical incision into the surface. The cells could be peeled off in layers of approximately three (3) nanometres at a time to establish the effect of the oil on the yeast cell’s composition. A nanometre is one thousandth of a micrometre.

Each cell was enlarged by between 40 000 and 50 000 times. This was done by using the Department of Physics’ PHI700 Scanning Auger Nanoprobe linked to a Scanning Electron Microscope and Argon-etching. Under the guidance of Prof. Swart, Mss. Swart en Leeuw could dissect the surfaces of yeast cells exposed to over-used cooking oil. 

The study noted wart like outgrowths - some only a few nanometres in diameter – on the cell surfaces. Research concluded that these outgrowths were caused by the oil. The exposure to the oil also drastically hampered the growth of the yeast cells. (See figure 1)  

Researchers worldwide have warned about the over-usage of cooking oil for deep frying of food, as it can be linked to the cause of diseases like cancer. The over-usage of cooking oil in the preparation of food is therefore strictly regulated by laws worldwide.

The UFS-research doesn’t only show that over-used cooking oil is harmful to micro-organisms like yeast, but also suggests how nanotechnology can be used in biological and medical research on, amongst others, cancer cells.

With the use of nanotechnology, it is possible to peel off the warts – some with a diameter of only a few nanometres – in layers only a few nanometres thick. At the same time, the 3D-structure of the warts as well as its chemical composition can be established.
