METHOD FOR ENHANCING BIOLOGICAL PHOTON RECEPTORS USING PLASMON RESONANCE

摘要

A method for enhancing the light detection capabilities of a chromophore. In one embodiment the method includes the steps of providing a plasmon resonant nanoparticle and placing the nanoparticle in close juxtaposition to the chromophore. In one embodiment the chronnophore includes 11-cis- retinal and the nanoparticle is a metal such as gold. In one embodiment the chromophore is chlorophyll. In another aspect the invention relates to an enhanced rhodopsin having a chromophore and a plasmon resonant nanoparticle in close juxtaposition with the chromophore. Yet another aspect of the invention is a method of enhancing vision in an eye including providing a plasmon resonant nanoparticle and placing the nanoparticle in close juxtaposition to a retinal molecule in the eye.
