Art lover Prof Janine Allen-Spies

Prof Janine Allen-Spies is an artist, lecturer in Fine Arts, and image philosopher from the UFS Department of Fine Arts. She teaches painting, drawing, and conceptual art to pre-graduate students and supervises postgraduate students in Fine Arts and other creative practices. In 2020, she was awarded the Stals Prize for her valuable role as a visual artist, academic, mentor, lecturer, activist, and supporter of art. 

What is the best thing about your job?
Working with artists and students who are energetic and passionate and love talking about art. 

What is the best and worst decision you have ever made?
As a second-year Art student, I modelled a psychedelic-looking bikini at a vintage clothing fashion show. Still makes me cringe! The best decisions weren’t really mine – they were godly interventions, so I can't claim them.

What was/is the biggest challenge of your career?
The biggest challenge is to make art. Even in the best circumstances, artmaking is ecstasy and agony. My biggest challenge as a mom is that I have two teenagers at home – working with students doesn't mean you know anything about younger teenagers.

What does the word woman mean to you?
As one of six sisters, I learnt that ‘woman’ implies diversity. We are all entirely different. Luckily, I don't have any preconceived ideas; all people should strive to be full-bodied human beings.

Which woman inspires you, and why?
Hypatia of Alexandria, Emily Hobhouse, Frida Kahlo, Princess Diana, and Caster Semenya – all women who do not fit into any mould. I am also inspired by my friends and my sisters and a lot of other local women.

What advice would you give to the 15-year-old you?
Make more of an effort to not grow up! Enjoy the beach, because one day you will not live close by. Your body is your own to take responsibility for and to love. Be strict with boyfriends and learn how and when to end a relationship, because nobody teaches you that.

What is the one self-care thing that you do? 
At the moment, the selfcare thing is visiting Nick, the hairdresser of Bella Donna who can fix, colour, and cut my hair, because managing my hair myself is just impossible.

What makes you a woman of quality, impact, and care?
I try to be self-reflective. To forgive and to be accepting are very important; we all have our fault lines, and we should work with each other's shortcomings. 
 
I cannot live without … coffee and ‘my’ psychologist.
My secret weapon is … honesty, and if my honesty fails, it will be having a Plan B.
I always have … fashion clothing items, even if I must make or alter clothing myself. My grandmother was a seamstress and we learnt to love clothing design.
I will never … again take the Free State landscape for granted.
I hope … poverty in the country will be addressed aggressively and in a more directed manner – which 
includes active participation and engagement of all people in South Africa.

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.
