You'd be surprised how accurate mice testing is. I'm in nanotechnology but yeah, recreating organ on chips is a HELLA interesting topic. Hopefully we'll see some lung on chip alternatives in the next decade or so, it'll help us improve medicine so much faster. God I love being in this science, I feel like the implications of Organ and Lab on chip in science and engineering is so underappreciated right now but it'll truly revolutionize testing one day.
