Hanoi (VNS/VNA) - A group of Vietnamese researchers at the University of Connecticut in the US have invented COVID-19 high-tech biological face masks and patches to deliver vaccines into the human body easily. Award winning Nguyen Duc Thanh, 37, and his research team, Nguyen Lab, used autolytic piezoelectric polymer sheets, which has been studied by themselves and applied in organ transplantation since 2018, to make a special type of face mask.
