Abstract
The invention describes a detection device that comprise nanostructures and which detection mechanism is based on the quantum confinement effects. The analyte species are sensed by measuring charge or/and energy transfer between the species and the nanostructures, which will be proportional to the overlap between the density of states distribution in the nanostructures and the density of states distribution in the targeted analyte species.
Claims23
A device for detecting biological and/or chemical materials produced by the process consisting essentially of:
- determining an energy level or an energy state distribution of an analyte;
- building a nanostructure or a plurality of nanostructures;
- adjusting a material composition, shape and size of the nanostructure or the plurality of nanostructures to produce the energy level or energy level distribution;
- arranging the nanostructure or plurality of nanostructures in an array;
- the energy state distribution over the array being the same as the analyte being detected;
- electrically connecting the nanostructure or plurality of nanostructures to electronics for monitoring the charge and/or energy transfer between the analyte and the nanostructures or plurality of nanostructures;
- wherein the charge or energy transfer occurs between the analyte and the nanostructure or plurality of nanostructures only when the energy level or energy state distribution of the analyte is substantially identical to that of the nanostructure or plurality of nanostructures.
