Antimicrobial Silver Coatings React To Chemo Drugs

Nanosilver coating harmful chemo

There is a growing belief, which isn’t being discussed much, that silver based antimicrobial coatings are harmful. The silver nano-coatings are used on everything from medical supplies to socks, becoming more and more ever-precent in our lives with minimal understanding of the effects of chronic exposure. While you shouldn’t go and throw out your running shirt, it is something to be aware of. Since we have touched on this before, when a study came out highlighting the effect silver coatings have on chemo drugs we thought it was worth bringing up again. A team of researchers from the Norwegian University of Science and Technology (NTNU) was examining potential issues in IV catheters used for chemo and found that silver used to prevent microbial growth was spurring an unfavorable reaction. Not only was the silver causing the chemo drug (5-Fu) to breakdown, the reaction was also releasing dangerous hydrogen fluoride gas. According to NTNU there have been relatively few studies as to how various drugs react to other substances and coatings they come in contact with. The good news is that there are other antimicrobial coatings, such as graphene, that are safe. Hopefully, thanks to studies such as the one at NTNU, they will become more widely used and help increase the effectiveness of cancer treatments.

Red Algae Could Lead To Odor-Free Clothes

Red AlgaeThe KTH Royal Institute of Technology in Sweden has developed an alternative to silver based anti-odor clothing. By utilizing a combination of bio-compatible plastic and a bacteria compound found in red algae (lanosol), KTH has crafted an antibacterial thread. Currently silver is used in clothing to accomplish the same thing. The new material is designed to solve two of the largest issues with silver based antibacterial fabrics. Silver is applied to clothing via nanoparticles and studies have shown that these particle often shed and are ingested. The long term ramifications of this is debated, but there are fears that because of its antibacterial properties the silver could have health consequences. Since the algae is spun into the threads, it is less likely to shed.
