Conclusions The proposed nanotechnology could allow the development of a new generation of integrated self contained nanofunctional devices incorporating multiple end-point sensing elements,optical quantum detectors and integrated electro-optic molecular switching capability. The obvious challenges are reducing the cost of materials and devices, improving reliability and packing the devices into useful products.
