This week in Nano: Week 12 (March 16th-22rd)


Nano Silver in Implants- A press release from the NC State Department of Industrial and Systems Engineering (ISE) describes how researchers there are engineering ways to apply a low-intensity electrical charge to a silver-titanium implant, releasing low-toxicity silver ions that kill or neutralize bacteria. The electrical charge is driven by a small power source and can be integrated into an implant - these orthopedic implants could help reduce infections after surgery and boost recovery times. The study showed a 99% decrease in bacterial growth around implants after 24 hours. Currently looking for paper to link.


The FDA (Food and Drug Administration responsible for regulating medicine and medical devices in the USA) have adopted 3 Nano standards. They relate to:
