TL;DR: In this article, the efficiency of nanostructures as surface enhanced Raman scattering (SERS) substrates is checked on cyanine-based dyes and horseradish peroxidase, evidencing detectable concentrations as low as 10 −7 to 10 −8 ǫM.

TL;DR: Aqueous solutions of silicon nanocrystals have been obtained, by sonication, from porous Si (p-Si) aged in air for various times, and the photoluminescence of these solutions changes with the aging time of p-Si as discussed by the authors.

TL;DR: In this article, the authors demonstrate an increase of 0.8% of the power conversion efficiency of the interdigitated back-contact cell by the silicon nanocrystals layer and prove that this increase is due to a combination of a better surface passivation, a better optical coating, and of the luminescent downshifting effect.

TL;DR: The time evolution of the photoluminescence properties of these hydrophilic silicon nanocrystals has been followed and these properties render Si-nc very useful as a labeling agent for biosensing.

TL;DR: In this article, a channel waveguide-based evanescent field optical sensors are developed to make a fully integrated chip biosensor, which senses fluorescent analytes immobilized within a micrometric sized bioreactor well realized within an optical waveguide.
