The present invention provides a safe, low-cost, quick and accurate method and apparatus for easily detecting a molecular structure. An apparatus having the following requirements. a) an array of test sites formed on a substrate for receiving a sample substance; b) a probe formed at a test site for binding to a molecular structure, wherein the probes at different test sites are of a predetermined predetermined type. Probes with different structures for binding to the molecular structure, and c) a detector array with multiple detectors. Each detector is located adjacent to the relevant test site, and the radiation propagates through the test site, and the site with the attached probe is to a different extent than the unattached test site. Absorbed, and this difference in the degree of absorption is sensed by the detector and used to generate a signal to identify the presence of a molecular structure in the sample material.
