Nanotechnology has much to offer Nigeria but research needs support

Egypt, South Africa, Tunisia, Nigeria and Algeria lead the field in Africa. Since 2006, South Africa has been developing scientists, providing infrastructure, establishing centres of excellence, developing national policy and setting regulatory standards for nanotechnology. Companies such as Mintek, Nano South Africa, SabiNano and Denel Dynamics are applying the science.

In contrast, Nigeria’s nanotechnology journey, which started with a national initiative in 2006, has been slow. It has been dogged by uncertainties, poor funding and lack of proper coordination. Still, scientists in Nigeria have continued to place the country on the map through publications.

The figures show steady growth in Nigeria’s publications. But the performance is low in view of the fact that the country has the most universities in Africa.The research performance is also low in relation to population and economy size.

 Nigerian nanotechnology research is limited by a lack of sophisticated instruments for analysis. It is impossible to conduct meaningful research locally without foreign collaboration on instrumentation. The absence of national policy on nanotechnology and of dedicated funds also hinder research.

Nanotechnology would benefit Nigeria in several ways. In agriculture, nanomaterials can be exploited as slow release fertilisers and eco-friendly agents against pests and diseases. There are applications in renewable and clean energy generation, through biofuels and solar panels.

In security, nanomaterials in gadgets and vehicles can enhance protection and capabilities of personnel. For example, there is potential for smart uniforms with ultraviolet protection, antimicrobial properties, camouflaging, and resistance to water and fire.

Nanomaterials can make drinking water safe through disinfection and removal of chemical pollutants. In healthcare, antimicrobial nanofabrics can help prevent hospital-acquired infections.
