Device and method for detecting organic molecules in a test substance

The invention relates to a measuring for detecting the material organic polymer, specifically biological molecule and a device. The device for invention comprises a test system (300), the test system comprises: A test point position (T) array testing, the material of power to the array; each test position of with the special molecular probe (320); A lighting system (100), by and a lighting test point position (T); sub-arrayWith a test system (400), for mounting the probe molecular (320) and a detecting the position detecting point (T) of polymer (350) interaction, a lighting system (100) comprises an relatively independent addressable light source (B) array; the lighting source to are to, so as to the subarray each test point position (T) is point at least one light source (B), the light source (B) a layer of illuminates wherein the detecting position of.
