Nanotechnology Has Much To Offer Nigeria But Research Needs Support
Nanotechnology is one of the engines of the fourth industrial revolution. The global market of nanotechnology-enabled products stood at approximately US$1.6 trillion in 2014. In one estimate, the industry could generate 6 million jobs and account for 10% of global GDP by 2030.
Nanotechnology creates, uses and studies materials at nanoscale - one nanometre is a billionth of a metre. Some of these materials occur in nature. DNA, proteins and viruses are examples. Others can be created by slicing larger molecules into smaller ones or by building up atoms into nanoparticles.
