The researchers from electronics and electrical communication engineering at IIT Kharagpur have developed the micro-pump and the micro-needle – thinner than a human hair to feed into the transdermal drug delivery systems painlessly.
While a human hair is 50-70 micrometers thick, the micro-needle is 55 micrometers thick. Developed with high strength glassy carbon, it can withstand the skin resistive forces.
The microneedles work using a pressurized and controlled micropump conveying the drug through the skin. The drug is pushed in the reservoir through the microneedle array by micro-pump. The rate of flow of drug molecules can be increased into the skin in a controlled and precise manner with the help of a micro-pump.
The union ministry of electronics and information technology and the department of science and technology has funded the project. Obeying the guidelines of medical science in India, the project was successfully tested with animals. Along with filing a patent in India for the device, this study is also published in Nature and IEEE journals.
Trees growing fast might die young
–Parnad Basu, Amity University Kolkata The fast-growing trees die younger whereas slow-growing trees don’t, reported in a recent study led by the University of Leeds. The study shows, among many things, temperature plays a significant role. An increase in temperature of one degree shortens the lives of these trees by approximately 30 years. Since the […]
