We have measured the optical properties of cancer and normal whole cells and lysates using light transmission spectroscopy (LTS). LTS provides both the optical extinction coefficient in the wavelength range from 220 to 1100nm and (by spectral inversion using a Mie model) the particle distribution density in the size range from 1 to 3000nm. Our current work involves whole cells and lysates of cultured...
Numerous epidemiological studies have linked carotenoids to cancer preventive processes, thereby increasing interest in levels of these micronutrients in human tissue and serum. Conventional analyses of these biological tissues employ liquid chromatography (LC) with ultraviolet and visible absorbance (UV–VIS) detection. However, this type of carotenoid analysis does not provide adequate sensitivity...
