Multiplexed surface enhanced raman sensors for early disease detection and in-situ bacterial monitoring
Sameer Walavalkar,Axel Scherer +1 more
TL;DR: In this paper, a thermal treatment can reflow the metal on the nanopillars forming metallic bulbs on the top end of the polygonal structures, and these structures can have enhanced optical detection when functionalized with biological agents, or can detect gases, particles and liquids through interaction with the metal layer on the polyhedral structures.
Journal ArticleDOI
Scalable Method for the Fabrication and Testing of Glass-Filled, Three-Dimensionally Sculpted Extraordinary Transmission Apertures
TL;DR: A new, scalable fabrication method and experimental characterization of glass-filled apertures exhibiting extraordinary transmission are presented, fabricated with sizes, aspect ratios, shapes, and side-wall profiles previously impossible to create.
Journal ArticleDOI
High-Q impurity photon states bounded by a photonic band pseudogap in an optically thick photonic crystal slab
TL;DR: In this paper, the density of in-plane Bloch modes can be controlled by creating additional photon feedback from a finite-size photonic-crystal boundary that serves as a low-Q resonator.
Patent
Plasmonics nanostructures for multiplexing implantable sensors
TL;DR: In this paper, a thermal treatment can reflow the metal on the nanopillars forming metallic bulbs on the top end of the polygonal structures, and these structures can have enhanced optical detection when functionalized with biological agents, or can detect gases, particles and liquids through interaction with the metal layer on the polyhedral structures.
Patent
Nano-pillar transistor fabrication and use
Aditya Rajagopal,Axel Scherer,Michael David Henry,Sameer Walavalkar,Thomas A. Tombrello,Andrew P. Homyk +5 more
TL;DR: A field effect nano-pillar transistor has a pillar shaped gate element incorporating a biomimitec portion that provides various advantages over prior state-of-the-art devices as discussed by the authors.
