Optical metasurfaces are planar metamaterials that can mediate highly precise light–matter
interactions. Because of their unique optical properties, both plasmonic and dielectric …

After the first visible photoluminescence (PL) from porous silicon (pSi), continuous efforts are
made to fabricate Si‐based compound nanomaterials embedded in matrices such as oxide …

Silicon-on-insulator (SOI) wafer is one of the most appealing platforms for optical integrated
circuit with the potential to realize high performance Ultra Large Scale Integration (ULSI) and …

A facile one-pot strategy was developed for the synthesis of lysozyme functionalized
fluorescence gold nanoclusters (AuNCs). The lysozymes added to reduce Au 3+ ions and …

In this study, we developed an efficient method based on magnetic Fe3O4-modified
graphene oxide (MNPs@ GO) along with aptamer-functionalized upconversion …

We have investigated photonic biosensing of bacteria based on photoluminescence (PL) of
GaAs/AlGaAs heterostructures. The method takes advantage of the GaAs PL sensitivity to …

Photocorrosion of semiconductors is strongly sensitive to the presence of surface states, and
it could be influenced by electrically charged molecules immobilized near the …

Raman microspectroscopy is now well established as one of the most powerful analytical
techniques for a diverse range of applications in physical (material) and biological sciences …

Culture-based methods for the detection of Legionella pneumophila are prohibitively slow
and frequently inadequate. The problem has been addressed with biosensing technology …

Staphylococcus aureus is a major human pathogen that elicits wide range of exo-toxic
proteins that are responsible for diverse disease symptoms in humans. In the present study …
