Abstract:
1. A system for detection, identification and quantification of a biological matter, having one or more light sources combined with one or more optical photosensors and various electronic components for obtaining and processing of a signal emitted by nanoprobes, the system comprising: the one or more light sources being located at a top portion of the system, composed of low energy solid state lasers or light emitting diodes which emit light, wherein the one or more light sources have a wavelength and a controllable luminosity intensity, the wavelength being in a range of between 400 nm and 800 nm and the controllable luminosity intensity ranging between 0.01 mW/cm the one or more photosensors, including at least one of amorphous, nanocrystalline and microcrystalline silicon thin films and ceramic semiconductors functioning on a wide range of wavelengths from infrared to ultraviolet, and provide qualitative and quantitative information based on a specific and selective hybridization of probes functionalized with metal nanoparticles; and a power source for the system provided via at least one of a conventional energy source and photovoltaic batteries, wherein the biological matter is not physically fixed to the one or more photosensors and the biological matter is placed on an opposite side of a substrate on which the one or more photosensors are deposited; and wherein the system is configured to transmit light from the one or more light sources through the biological matter and the substrate and then receive the transmitted light with the one or more photosensors, such that the substrate on which the biological matter is to be deposited is located between the one or more light sources and the one or more photosensors, and the one or more photosensors are configured to measure an amount of light absorption by the biological matter.
