Finger-Actuated Microneedle Array for Sampling Body Fluids

The application of microneedles (MNs) for minimally invasive biological fluid sampling is rapidly emerging, offering a user-friendly approach with decreased insertion pain and less harm to the tissues compared conventional needles. Here, finger-powered microneedle array (MNA) integrated microfluidic chip was conceptualized extract body samples. Actuated by finger pressure, device enables an efficient user collect their own fluids in simple fast manner without requirement healthcare worker. processes extracting human blood interstitial (ISF) from flow across device, estimating amount extracted fluid, were simulated. design this work can be utilized personalized medical equipment usage procedure.
