Heidedal Drug Awareness Campaign
Pastor shares with Heidedal learners how drugs landed him in prison.
His father died when he was just three years old. A mourning single mother had to raise three boys. As the middle child, feeling abandoned and unloved, he joined a gang. Home was a cold and empty place and so were the streets of Grabouw, a small town in the Western Cape where he grew up. This is how Ivor Swartz’s story began.

A 15-year-old Swartz told himself: “Because I am not loved at home, maybe I will feel loved on the streets.” It did not take long for the ugly truth to emerge. When it did, he turned to drugs for comfort.

Behind bars

One evening when Swartz and a friend were at a local tavern, they were involved in an altercation. They pulled out guns and fired shots at two males. “My judgement was clouded by the drugs so my friend and I shot my blood brother,” he remorsefully reminisces. 

From prisoner to pastor

Swartz was imprisoned for six-and-a-half years, during which time he matriculated. He has been a free man for 14 years. For the past five years Swartz has been a youth pastor at St. Paul’s United Church in Johannesburg. He has also trained as a life coach and holds an Honours degree in Theology from the University of Pretoria.

Swartz shared the story of how drugs almost ruined his future with 1100 Olympia Primary School learners in Heidedal recently. He was the guest speaker at a two-day Community Outreach Drug Awareness campaign led by the University of the Free State’s (UFS) Division for Organisational Development and Employee Wellness.

Compassionate beyond campus

Burneline Kaars, Head of the Division, said the campaign is one of the ways in which the university shows that it cares for the community. “We strive to improve the wellbeing of staff and the community at large.”

Swartz and the UFS team visited seven schools in Heidedal from 10-11 July 2019. where they cautioned future leaders and parents against how drugs shape the choices that individuals make. 

Pursuing a better story

Swartz was sitting in solitary confinement when he heard a song by UK singer Robbie Williams. The lyrics were: “Cause I got too much life running through my veins going to waste.” These words changed his life.

“I decided I wanted a better life,” said Swartz. He now lives to make a positive contribution to society and has written a new conclusion to his life’s story.

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.
