PASADENA, Calif., April 14, 2022 — Researchers at the University of Southern California (USC) developed a printing technique that could provide the precision required to successfully 3D-print microfluidic channels on chips at a scale not previously seen. The technique is called in situ transfer vat photopolymerization (IsT-VPP). The use of microfluidic devices — compact testing tools composed of tiny channels carved on a chip — can lower the cost of drug development and aid in medical diagnostics. The traditional approach to fabricating these devices, soft lithography in a cleanroom setting, requires multiple...Read full articleRelated content from Photonics MediaARTICLESLight-Responsive Hydrogels Safely Deliver Targeted TherapiesA research team at Texas A&M University is using nanomaterials that absorb near-infrared (NIR) light to develop and manipulate light-responsive hydrogels.
