Vibrational spectroscopy, including infrared and Raman optical spectroscopy, is an instrumental technique for fingerprinting molecular structures and the chemical compositions of different materials.
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.
The Dionne lab has developed ultrathin and compact devices for electrically driven beamsteering that fit on a semiconductor chip. These devices rely on resonant dielectric nanostructured surfaces known as "high quality factor" (high-Q) metasurfaces.
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 researchers have developed an integrated printer/scanner platform to screen biofluids for bacterial pathogens and other cells of interest at the single cell level.
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.
Stanford researchers within the Dionne Lab have developed a method to use copper titanium dioxide core-shell nanoparticles for the light driven production of green fuels or removal of contaminants in water.
Stanford researchers at the Dionne Lab have introduced new vibrational spectroscopy, termed electron- and light induced stimulated Raman (ELISR) scattering, in electron microscopy for simultaneous high-resolution chemical mapping of various samples.
