Episode 468 - Stopping frostbite and bacteria using chemistry and physics

January 31, 2022

How can we protect skin from frostbite before it happens? Scientists freeze cells in the lab all the time, so how can that be used to help prevent frostbite? When treating frostbite minutes can make a huge difference. How can we improve prevention of the worst injuries from frostbite? You've heard of sunscreen but what about frostbite cream. Antiobiotic resistance is a serious issue, but what plasma could be a secret weapon. Using plasma we can engineer antimicrobial surfaces. Plasma sintered surfaces can wipe out bacteria.
