New Technology Makes 3D-Printed Medical Diagnostic Devices Accessible and Affordable February 5, 2021 Devices with intricate interlacing channels, the width of a human hair, that move minuscule amounts of liquids, and can be used to diagnose and treat complex diseases, can now be made using a cost-effective, quick, and reliable method. A recent study by a team of scientists at the University of Bristol describes a method for the rapid development of complex microfluidic devices made of polymers using 3D-printed interconnecting microchannel scaffolds and open-source resources developed by the team. This breakthrough technology is reported in the Popularly called bedside testing, remote testing, mobile testing, or rapid diagnostics, clinical testing that can be performed at the site of patient care rather than in a laboratory, is the essence of point-of-care (POC) testing. POC testing tools are made possible through lab-on-a-chip (LOC) technologies that have gained wide popularity over the last few decades as the answer to biological, chemical, and global-healthcare challenges.
