Abstract
In the current study, we had obtained the spectral features of biomolecules of blood plasma, urine and bladder wash of a certain set of the patients of bladder cancer. The fluorescent biomarkers such as tryptophan, tyrosine, collagen, elastin, flavin and porphyrin, in the above body fluids are distinctly from those of normal controls. This study indicates the potential application of optical biopsy for bladder cancer detection.
