March 21, 2022

Scientists at the Wyss Institute for Biologically Inspired Engineering (Wyss), Harvard University, have successfully modelled the human immune system on microfluidic chips. Most medical innovations such as vaccines sometimes fall short of expectations in live human experiments – instead of relying on lab cultures and animal studies, cells on chips mimic the physical conditions as […]
