Application of a suitable optical radiation flux to the double-nanohole structure can provide a folding and/or binding of protein molecules that can be identified based on changes in optical transmission. Varying nanohole transmissions can thus be associated with trapping, binding and unfolding of biological particles. The double-nanohole defines cusps, but such cusps can be defined in other ways as well."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"System for trapping, interacting and modifying single protein molecules using a double-nanohole structure","description":"Molecules or particle having a hydrodynamic radius as small as 3.5 nm can be trapped using a double-nanohole structure defined in a metal film or other metallic layer.
