“Running provides me with a platform to reach others, to bring hope, to make people realise that anything is possible if you are prepared to work hard for it,” says Louzanne Coetzee, our very own home-grown all-round achiever, who is fun-loving, relatable, and inspiring. A South African para-athlete, Coetzee was born blind as a result of a hereditary condition called Leber congenital amaurosis, and competes in the T11 disability class for athletes with the highest level of visual impairment. Coetzee enjoys an integrated life, with an interest in baking, watching movies, walking and hiking, cycling, being part of a church band, public speaking, coupled with some artistic hobbies.

Our podcast guest

Coetzee competed at the 2020 Tokyo Paralympic Games this year, where she won a silver medal in the 1 500 m final alongside her guide Erasmus Badenshorst, setting a new African record of 4:40.96. She also competed in the women’s mixed class marathon (T11 and T12 for the visually impaired) with her guide Claus Kempen, improving the world record by 1 min 42 sec and her personal best from 3:13:41 to 3:11:13. 

In 2018, Coetzee competed in three events at the Para Athletics event in Berlin, Germany – the 800 m, 1 500 m, and 5 000 m. She set a new African record in the T11 800 m race, taking the silver medal, as well as a bronze for the 1 500 m race. In 2018, Coetzee also broke the 5 000 m (women) world record in her disability class, while in the same year she became the first visually impaired athlete to compete at the World University Cross Country Championships in Switzerland. 
Coetzee set a new world record in the 5 000 m T11 category for the first time at the Nedbank National Championships for the Physically Disabled in March 2016. Moreover, with her performance of 19:17.06, Coetzee shattered the Lithuanian athlete Sigita Markeviciene’s 16-year record of 20:05.81, set at the 2000 Paralympics in Sydney. Coetzee became the first totally blind female to clock sub-20 minutes in the 5 000 m.

Her involvement in her society stretches beyond sports, and as a student, she formed part of the University of the Free State Student Representative Council. She was also an athlete representative on the Free State Academy of Sport’s executive committee.

In 2014, she became the first visually impaired student to be elected to the UFS Student Representative Council (SRC), with the portfolio Student Accessibility. From 2015 to 2017, she was a research assistant in the Institute for Reconciliation and Social Justice at the UFS, and in 2016 she also acted as junior lecturer in a computer module for students with visual impairments. From 2017 to 2018, she was Residence Head of Arista Ladies City Residence, and she is currently the Residence Head of Akasia Residence at the UFS.  

Coetzee boasts several accolades from the UFS. She was named the 2014 Senior Sportswoman of the Year by the Free State Sport Association for the Physically Disabled (FSSAPD). In 2017, she and her guide Khothatso Mokone received a Special Award for Disabled Sport at the KovsieSport Awards. In 2018, she won the Free State Sports Star Award, and was named Sports Star of the Year (period June 2018 to April 2019) by the Free State Sport Association for the Physically Disabled. 

Coetzee’s academic qualifications include a BA and BAHons in Integrated and Corporative Marketing Communication, and an MA in Social Cohesion and Reconciliation – all from the University of the Free State.

François van Schalkwyk and Keenan Carelse, UFS alumni leading the university’s United Kingdom Alumni Chapter, have put their voices together to produce and direct the podcast series.  Intended to reconnect alumni with the university and their university experience, the podcasts will be featured on the first Monday of every month, ending in November 2021.  Our featured alumni share and reflect on their experiences at the UFS, how it has shaped their lives, and relate why their ongoing association with the UFS is still relevant and important. The podcasts are authentic conversations – they provide an opportunity for the university to understand and learn about the experiences of its alumni and to celebrate the diversity and touchpoints that unite them.

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.
