Abstract: A system and method of identifying a print includes an image-capturing and lighting optical system configured to maximize specular reflection of light reflected from a print and to minimize diffused reflection of light reflected from a background surface of the print via adjustment of at least one of a frequency and a reflection angle of the light emitted upon a sample of the print. The system and method also include an IC having one or more FETs with a nanostructure configured to detect a plurality of analytes from the print. The system and method also include a nucleic acid analyzer configured to process the print and to determine a DNA content of the print. There is no contact made with the print, while being subjected to processing by the image-capturing and lighting optical system and the IC.
