The Department of Science and Technology (DST) wants to ramp up SA's nanotechnology research output over the next few years, in what it said could improve solutions found in fields including biotechnology, energy and pollution treatment.
The DST and Rhodes University recently unveiled the Time-of-Flight Secondary Ion Mass Spectrometer (TOF-SIMS) - a R17 million device that produces a mass spectral map of a surface area, and has high surface sensitivity essential for the detection of contaminants.
The equipment, which the DST says is the first for SA, will also help researchers in green chemistry, forensic sciences and sustainable development.
Speaking at the unveiling ceremony on Friday, science and technology minister Naledi Pandor said the TOF-SIMS would make it much easier for local researchers to quantify nanostructured materials and not have to rely on overseas collaborators.
Professor Janice Limson, director of Rhodes University's Biotechnology Innovation Centre, says ongoing research at the Eastern Cape-based tertiary institution aims to unearth innovative and commercialisable solutions. "Our nanobiotechnology research group is looking into the development of sensors and in accessing alternative energy from waste products.
"Taking an applied electrochemistry approach, much of the research seeks to harness the potential of nanostructured materials in realising these goals," she said.
According to Pandor, the National Nanotechnology Strategy, which was published in 2005, initially focused on adopting formal teaching programmes in the field, with more than 1 100 papers being published by tertiary institutions.
She said more than 20 patents have been filed, and government wants more South African-developed nanotechnology-enhanced products to enter the market in the coming years.
"The availability of the TOF-SIMS in the country will enhance the quality of research and training. The equipment will assist in advancing requirements to address the national skills shortage in many key areas of research," added Pandor.
Increased focus on biotechnology has also been highlighted by the Gauteng provincial government, which recently unveiled a dedicated facility in Pretoria.
