Lycurgus cup [ 1 ] created by ancient Romans 2000 years ago can appear different colors depending on the direction of light illumination in which it is viewed due to metal nanoparticle optical scattering. It has inspired nanoplasmonics research over

We report a fundamentally new approach to enhance fluorescence in which surface adsorbed fluorophore-tagged biomolecules are excited on a photonic crystal surface that functions as a narrow bandwidth and tunable mirror of an external cavity laser. Th

A process that combines polymer nanoreplica molding with horizontal dipping was used to fabricate large area (~ 3 × 5 inch2) distributed feedback laser biosensors (DFBLB) on flexible plastic substrates, which were subsequently incorporated into stan

All fluorescent assays would benefit from greater signal-to-noise ratios (SNRs), which enable detection of disease biomarkers at lower concentrations for earlier disease diagnosis and detection of genes that are expressed at the lowest levels. Here,

We demonstrated a single-mode and biomolecule-induced tunable external cavity laser biosensor. This system achieves large dynamic range, high-Q resonance, and self-referencing through dual-mode lasing for high sensitivity label-free detection.
