Human Rights 18 March 2024

Echoing the words of Nelson Mandela, Prof Francis Petersen, the Vice-Chancellor and Principal of the University of the Free State (UFS), emphasised the profound significance of human rights. “To deny people their human rights is to challenge their very humanity,” he said during his opening address at the Human Rights Celebration held by the UFS Faculty of Law on 18 March 2024.

Acknowledging the pivotal role played by stalwarts such as Emeritus Justice Albie Sachs and Sir Sydney Kentridge, Prof Petersen delved into the strides made since the inception of South Africa’s contemporary constitution.

Underlining the university’s unwavering commitment to human rights, Prof Petersen added, “For universities, it remains critical that every aspect of academic life is viewed through the lens of human rights. The principle of equality lies at the centre of our purpose and operations.”

Furthermore, Prof Serges Kamga, Dean of the Faculty of Law, highlighted the institution’s vision encapsulated in Vision 130, striving to produce graduates who embody excellence and contribute to societal transformation.

Panel discussion: Sir Sydney Kentridge’s enduring legacy

Former Justice Zak Yacoob, renowned for his tenure at the Constitution Court of South Africa, paid tribute to Sir Sydney Kentridge in a panel discussion focusing on Kentridge’s contributions to human rights both nationally and internationally.

Reflecting on his personal experiences working alongside Sir Kentridge, Justice Yacoob highlighted the practical essence of human rights advocacy. He recounted Sir Kentridge’s seminal role in shaping the constitutional court’s early judgments, particularly emphasising the incorporation of human dignity into the constitutional framework.

Justice Yacoob’s insights shed light on the profound impact of Sir Kentridge’s jurisprudence on society, particularly in shaping notions of dignity, equality, and freedom. “The contribution he made was absolutely amazing. He wrote the first-ever judgement delivered by that court in April 1995. It was the first judgement that brought forth the issue of human dignity and its importance.”

Joining the discussion were esteemed panelists including Honourable Madam Justice Yvonne Mbatha and Dr Adri Du Plessis, who provided expert commentary on Sir Kentridge’s contributions to the legal fraternity. The discussion was moderated by Prof Elsabe Schoeman, Dean of the Faculty of Law at the University of Pretoria.

Honouring legal icons

Vanessa Rose September, Chair of the Albie Sachs Trust, presented books donated by the trust. The biography titled Arthur Chaskalson: A life dedicated to justice for all chronicles the life of Chaskalson, a towering figure in South Africa’s legal landscape.

Emeritus Constitutional Court Justice Albie Sachs delivered a thought-provoking lecture, pondering the question of whether there is cause for celebration on the 30th anniversary of human rights in South Africa.

With a rich history of activism and legal scholarship, Justice Sachs reflected on the evolution of South Africa’s judiciary and the enduring legacy of the Constitutional Court. Despite acknowledging prevailing challenges, Justice Sachs remained optimistic, citing the country’s constitutional framework as a beacon of hope and progress. “There’s lot to be angry about, there’s lots to complain about, there’s lots that has to be renounced, but there’s lots to celebrate. We’ve got a country, we’ve got a constitution, we’ve got rights, we’ve got instruments that we can use,” he said.

In conclusion, the Human Rights Celebration served as a poignant reminder of the ongoing struggle for dignity, equality, and justice, reaffirming the university’s steadfast commitment to upholding these fundamental principles in academia and beyond.

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.
