Collagen fluorescence measurements on nanosilver treated leather

摘要

Silver ions are a strong antiseptic with a broad spectrum. Treatment of textiles andleather with nanosilver particles is a new idea for real clean wear. The nanometer-size particles have alarge specific surface resulting in the release of silver ions in antiseptic concentration. One way toinvestigate nanosilver treated leather is the intrinsic fluorescence of organic material. Thisfluorescence is provided mainly by collagen content. Fluorescence spectrum shows an interactionbetween silver and collagen.
