Abstract:In this work, smartphone-based surface plasmon resonance imaging is used for the near-field mapping of a liquid sample’s concentration distribution. The principal design uses a special coupler based on a parallel incident light beam with p-polarization from a smartphone screen; this light is used to excite surface plasmons on a gold layer 50 nm thick. Using a bespoke application, surface plasmon resonance (SPR) intensity changes are detected in the SPR images captured with the front-facing camera. The SPR inte… Show more
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
