Chitosan light absorption
WebNear-infrared light generally refers to light within the wavenumber range of 12,500 to 4,000 cm -1 (wavelengths from 800 to 2,500 nm) (see Fig. 1). Absorption of near-infrared light, like that of mid-infrared light, is based on the vibration of the material. WebChitosan, the second naturally abundant polysaccharide, has shown promising anticancer activity against many cancer cells. There are various chitosan nanoparticle preparation techniques.
