NYU student Joe Landolina who’s studying for a bachelor’s in bio-molecular chemical engineering and a masters in biomedical engineering, created Veti-Gel. It basically recreates the naturally occurring polymers in the body that clot blood on contact. Continue reading for the video – if you’re squeamish over blood, we recommend skipping it.

Here’s how it works: “A two-part process, Veti-Gel uses a plant-based hemophilic polymer that grabs onto the blood and ‘snaps it back together to seal the wound’. Another polymer then replicates the skin tricking the body into thinking it is skin. Gamma-sterilized, it has antimicrobial properties and used by surgeons in sterile environments is a safe, disinfecting way to heal a wound.
