TL;DR: A multifunctional chip based on surface-enhanced Raman scattering (SERS) that effectively captures, discriminates, and inactivates pathogenic bacteria and enabled sensitive and specific discrimination of Escherichia coli and Staphylococcus aureus from human blood.

TL;DR: The first demonstration of a portable silicon-based SERS analytical platform for signal-on detection of trace trinitrotoluene (TNT) explosives, made of silver nanoparticle (AgNP)-decorated silicon wafer chip, which can couple well with a hand-held Raman spectroscopic device using 785 nm excitation, suitable for qualitative analysis of trace TNT.

TL;DR: The first example of a silicon nanoshuttle-based security ink simultaneously featuring attractive optical and magnetic properties, suitable for fluorescent and magnetic anti-counterfeiting and encryption is presented.

TL;DR: A polyadenine-assisted, surface-enhanced Raman scattering (SERS) silicon chip composed of core (Ag)-satellite (Au) nanoparticles (Ag-Au NPs)-decorated silicon wafers for high-performance Pb(2+) detection and can be used for accurate and reliable determination of unknown Pb (2+) ions in real systems including lake water, tap water and industrial wastewater, with the RSD value less than 12%.

TL;DR: A novel kind of universal SERS chip, made of graphene (G)-silver nanoparticle (AgNP)-silicon (Si) sandwich nanohybrids (G@AgNPs@Si), in which AgNPs are in situ grown on a silicon wafer through hydrofluoric acid-etching-assisted chemical reduction, followed by coating with single-layer graphene via a polymer-protective etching method, that enables simultaneous capture, discrimination, and inactivation of bacteria.
