In atom beam lithography, a beam of kilo-electron-volt helium atoms illuminates a stencil mask and transmitted beamlets transfer the mask pattern to resist on a substrate. It shares the advantages of masked ion beam lithography but is immune to charg

Chemical mapping of molecules adsorbed on plasmonic nanostructures is a powerful technique for biomolecular sensing, surface chemistry and plasmon-matter interactions. DC-sputtered gold nanoisland (GNI) substrates have attracted significant attention

Plasmonic metal nanostructures have shown great potential in sensing, photovoltaics, imaging and biomedicine, principally due to the enhancement of local electric field by light-excited surface plasmons, i.e., collective oscillation of conduction ban

Ion beam proximity lithography (IBL) is a technique where a broad beam of energetic light ions floods a stencil mask and transmitted beamlets transfer the mask pattern to resist on a substrate. With a depth-of-field up to 20000 times larger than the

A new and compact fluorescence biosensor is constructed. The distinguished feature of this setup is the use of an ellipsoidal reflector as an optical collector of the fluorescence light. A traditional collecting lens with numerical aperture of 0.5 ca

A multi-point, side-firing design enables an optical fiber to output light at multiple desired locations along the fiber body. This provides advantages over traditional end-to-end fibers, especially in applications requiring fiber bundles such as bra

We present two innovative design concepts of integrated flexible neural probe for deep brain optical stimulation and electrical recording, termed as “optitrode”. In the first one, a hybrid annular light pipe is built around a tetrode by V-groove

Surface-enhanced Raman spectroscopy (SERS) has been widely used for high-sensitivity molecular detection and identification. It is advantageous for a SERS substrate to have a large surface-to-volume ratio from the standpoint of high density “hot sp
