Abstract:
1. An apparatus for identifying an unknown DNA sample, said apparatus comprising: a plurality of detection nodes, each of said detection nodes operable for allowing an interaction between a known DNA sample and an unknown DNA sample, and for generating an output signal if hybridization occurs between said known DNA sample and said unknown DNA sample; and a decoder operative for receiving an input signal indicative of which of said plurality of detection nodes should be selected for processing, and for outputting control signals which operate to activate said selected detection node; wherein each of said detection nodes includes a light source and a photodetection circuit, said photodetection circuit having a conductance value which varies if hybridization occurs between the known DNA sample and the unknown DNA sample deposited in said detection node, said change in said conductance value is operative for generating said output signal, wherein each detection node further comprises:
