Subwavelength nanostructures for optical biosensing and rapid photochemical reactions
… illumination. Second, 3D nanostructures for optical biosensing have been investigated. We demonstrate optical spectroscopy by using subwavelength dielectric nanostructures as the substrate material for localized surface plasmon resonance metallic nanoparticles. Nanostructured substrates made …

Surface Enhanced Infrared Absorption on Au Nanoparticle Films for Optical Biosensing
… prepared Au nanoparticle (AuNP) films. Optical properties of AuNP films were investigated with VIS spectroscopy; it was shown, that it is possible to describe these properties with effective media theories. The SEIRA activity was analysed by FTIR spectroscopy of adsorbates on AuNP films …

Design, fabrication and characterization of resonant waveguide grating based optical biosensors
… home based point-of-care diagnostics. Label-free optical biosensing with high sensitivity, throughput, compactness, and low cost, plays an important role to resolve these diagnostic challenges and pushes the detection limit down to single molecule. Optical nanostructures, specifically the resonant …

Multiresonant Plasmonics with Spatial Mode Overlap
… is useful for photodetection, light emission, optical biosensing, and spectroscopy. However, conventional plasmonic devices are optimized to operate in a single wavelength band, which is not efficient for wavelength-multiplexed operations and quantum optical applications involving multi-photon …

Novel Cell Penetrating Peptides Effect Endosomal Escape and Deliver Protein Cargos into Living Cells
… and purified from E. coli BL21 (DE3)pLysS. Optical biosensing experiments demonstrated that affinity and kinetics between the novel CPP and cargo proteins did not significantly differ from wild-type interactions; all had subnanomolar affinities. Cargo proteins were labelled with DyLight 550. …

Eph-Ephrin Signaling and the Role of EFN-4 in Caenorhabditis Elegans Nervous Systems Development
<p>Eph receptor tyrosine kinases and their ephrin ligands are required for multiple aspects of nervous system development including axon outgrowth, synaptic plasticity, and the formation of topographic maps in the visual system. The <em>Caenorhabditis elegans </em>ephrin-A, <em>efn-4</em>, has a …
