International Nurses Day, which is celebrated around the world on 12 May, celebrates the contribution of nurses to the healthcare of individuals, societies, and communities. The contribution of nurses during the pandemic cannot be overstated, and it is essential that such contributions are brought to light and that all nurses and nursing-related staff be appreciated.

This is according to Dr Champion Nyoni, Senior Researcher and Lecturer in the School of Nursing at the University of the Free State (UFS). The theme for the Day is Nurses: A Voice to Lead. The sub-theme is A Vision for Future Healthcare. Dr Nyoni says it is an important date on the calendar of the nursing profession.

The future of nursing 

Says Dr Nyoni: “A lot has happened in 2020 and more will happen in the future. The COVID-19 pandemic brought various challenges to the healthcare system and nurses have been at the coalface of these challenges. The mental health of nurses has been challenged, their resilience tested, and their teamwork strengthened. 

“In the future, a collective approach related to the function and role of nurses needs to be enhanced; the growth of the nursing profession is essential, and nurses will continue this work through enhancing their professional identity, their professional role, their own research, and also through teamwork with other professionals.”

The future of nursing is bright. The past 60 years have shown rapid advancements in the professionalisation of nursing – from being an altruistic occupation to a profession with legal status in many countries, says Dr Nyoni. The science of nursing has been growing exponentially, with several nursing-specific research and research led by nursing scientists. The impact of nursing research continues to be aligned with improved healthcare and health outcomes in many settings across the globe. 

“Nurses continue to be celebrated for their tireless efforts in influencing healthcare and health outcomes, in addition to being the single largest health professional body in the world. The world requires more professional nurses, not only by qualification but by necessary and appropriate context-specific competencies aimed at universal healthcare.” 
“Nurses have to look towards negotiating new healthcare spaces where their professional roles, though indispensable, are aligned with future population healthcare needs. In the same vein, the nurse of the future needs to embrace the Fourth Industrial Revolution and its potential influence on the profession,” says Dr Nyoni.

UFS preparing nursing students for future 

The UFS School of Nursing is at the forefront of nursing education in South Africa in terms of preparing competent professional nurses who meet the healthcare needs of our population and the future. “Our undergraduate programme is aligned with the primary healthcare approach, which is a complex healthcare model that underpins the health delivery system in South Africa and many low- and middle-income countries. Through state-of-the art facilities, our students engage with top nursing experts who facilitate and guide their learning.”

Dr Nyoni, who became the first UFS staff member and only the third African to win the prestigious Sigma Emerging Nurse Researcher/Scholar award, says the postgraduate nursing programmes at the UFS are driven towards producing independent thinkers who are able to significantly contribute to the development of nursing and healthcare, not only in South Africa but also in the rest of Africa. The students, drawn from all over the continent ؘ – says Dr Nyoni – are challenged to engage in research that makes a contribution to their own nursing practice and context. 

Research being done in the School of Nursing 

Two established research niche areas drive the research agenda in the School of Nursing, namely the ‘transfer of learning’ and ‘health communications’ research niche areas. In the transfer of learning through the research niches, various research projects are in place – all aimed at improving the quality of nursing education, which in turn result in quality graduates who will influence health outcomes. 

“Currently, various projects such as ‘emotional intelligence in nursing’, ‘online education of clinical preceptors’, ‘professional identity in nursing’, ‘self-directedness among nursing students’, and ‘extended reality in nursing education’ are some of the ongoing research projects aimed at improving the nursing education agenda and improving student experiences of nursing education,” Dr Nyoni explains some of the work being done in the School of Nursing. 

In the health communication research niche, several projects have been initiated in South Africa, Lesotho, and Kenya, and have been reported in several national and international fora. Both of these research niche areas are engaged in national, Africa-wide, and global research collaborations.  

A new research centre in the School of Nursing is about to be launched, focusing on reproductive, maternal, neonatal, and child health (RMHC).

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.
