We've heard how polyphenols in green tea can help slow the progression of CLL in some patients. Here's news of some promising research on how polyphenols from green tea, dark chocolate or red wine when mixed with salt can provide a very sticky anti-fouling coating for medical implants.
“The coatings innately have properties that are very beneficial to saving lives and keeping people healthy," says Tadas S. Sileika, a graduate student in Messersmith’s lab and first author of the paper detailing the research. "Without any further modification, they can help prolong the life of a medical device, reduce inflammation in a patient and prevent bacterial infections.”
Fouling is a huge problem with implants, so it will be a significant low cost breakthrough if this pans out.
