Nano-sized vesicles with ACE2 receptor could prevent, treat infection from current and future strains of SARS-CoV-2

First Nano-Sized Molecular Device Capable of Sensing and Altering Cells’ Bioelectric Fields
A conceptual drawing of the new molecular device. For experiments outside the human body (in vitro), the device would nest on the cell’s membrane: a “reporter” molecule would detect the local electric field when activated by red light; an attached “modifier” molecule would alter that electric field when activated by blue light.
