All it took for inspiration to develop a painless injection was a mosquito bite. Yes, a mosquito uses a unique method to deliver a painless bite and researchers at IIT Kharagpur wondered if they could make an injection that mimicked the mechanical action involved. While most of us think that a mosquito bite hurts, in reality, the irritation is due to chemicals in its saliva. After three years of research, IIT-Kgp, along with the Tokai University of Japan, has invented this novel injection that uses a microneedle to extract blood or deliver drug painlessly by using the same suction-based pressure that a female mosquito uses to suck blood. The diameter of the needle is just 30 micro metre. Besides others, this injection will especially benefit diabetes mellitus patients as blood tests are critical for its diagnosis and management. These patients have to check their blood gl...
