Figure 3From: Photochemical tissue bonding with chitosan adhesive films (A) The absorption spectrum of the rose adhesive shows two peaks at 526 and 562 nm. The green laser (λ = 532 nm) was thus strongly absorbed by the adhesive during PTB. (B) The absorption spectrum of the chitosan film without RB. These films poorly attenuated visible light. (C) The absorption spectrum of RB dissolved in deionised water ([RB]~5*10-6 molar). The peaks are shifted to 516 and 548 nm.Back to article page
