New rubber-like material could replace human tissue
Researchers have created a new rubber-like material based on plexiglass that could act as a replacement for human tissue in medical procedures
Insect wings hold antimicrobial clues for improved medical implants
Some insect wings such as cicada and dragonfly possess nanopillar structures that kill bacteria upon contact. However, to date, the precise mechanisms that cause bacterial death have been unknown
Now metal surfaces can be instant bacteria killers
Bacterial pathogens can live on surfaces for days. What if frequently touched surfaces such as doorknobs could instantly kill them off? Thanks to new laser treatment technique
