Abstract

We have extended the optical characterization of collagen powder in the NIR range (610-1080 nm). This evidenced the presence of an absorption peak at 1020-1030 nm that could prove useful for the quantification of collagen in vivo. We have also measured the first absorption and scattering spectra of breast in vivo from 610 to 1080 nm from 7 healthy volunteers, proving the feasibility of optical measurements above 1000 nm.
