This nanoparticle platform for electric field detection is the first inorganic platform to use both intensity and spectro-ratiometric (relative color change) readout for the determination of local electric fields in vitro, in vivo, and in situ.
Stanford engineers have developed and tested a nanostructured thin film material that upconverts infrared to visible light and combines electrical and non-linear optical properties in the same layer.
Stanford researchers have designed a powerful plasmonic coaxial aperture as a low-power optical trap for nanosized specimens, a regime that is inaccessible with the other designs.
