Nanosensors Based on DNA and RNA Aptamers and Semiconductor Quantum Dots
Abstract
In this entry, novel nanosensors based on the use of DNA and RNA molecules that selectively bind to analytes in combination with 1) nanoscale donor complexes or 2) semiconductor quantum dots are discussed. Of central importance in these novel nanosensors are DNA or RNA molecules that change their conformational state when they bind selectively to an analyte. This conformational change is exploited to produce an electrical signal from a nanoscale donor complex or an optical signature from a semiconductor quantum dot. Selected examples of such nanosensors are given for the cases of electrical and optical output signals.
