New Microneedle Makes Injections Painless
Different microneedle technologies are being researched by many groups for painless vaccines and drug delivery systems, but Sahan Ranamukhaarachchi, a PhD student in UBC‘s faculties of applied science and pharmaceutical sciences, developed this technology to monitor drugs painlessly, specifically vancomycin. But this new microneedle delivery system comes as a thin, small patch that is pressed against a patient’s arm during medical treatment. The patch contains a tiny needle-like projection that painlessly measures drugs in the bloodstream without drawing any blood. The needle resembles a hollow cone and is less than half a millimeter long.
