Abstract

A placement multi-band bioassay device makes use of a light source illuminating by several specific wavelengths, or several tunable wavelengths, or employs a device capable of capturing spectral medical images of specific bands inside the human body, e.g., the digestive system, the oral cavity, the nasal cavity, the anus, and the vagina, so as to decide the nidus. Higher discrimination rates can be obtained for some diseases or supernumerary cells to accomplish the object of “prevention is better than cure”.
