Over the decades, application of mechanical force to influence chemical reactions has been called by various names: mechanochemistry, tribochemistry, alloying, name but a few. The evolution these terms largely mirrored understanding field. But what is meant terms, why have they evolved, and does it really matter how process called? Which parameters should be defined describe unambiguously experimental conditions such that others can reproduce results, or allow meaningful comparison between processes explored under different conditions? Can information on encoded in clear, concise, self-explanatory way? We address questions this Opinion contribution, which we hope will spark timely constructive discussion across international mechanochemical community.

Tailoring noble metal nanoparticle designs to enable sensitive lateral flow immunoassay

Theranostics, Journal Year: 2021, Volume and Issue: 12(2), P. 574 - 602

Published: Dec. 15, 2021

Lateral flow immunoassay (LFIA) with gold nanoparticles (AuNPs) as signal reporters is a popular point-of-care diagnostic technique. However, given the weak absorbance of traditional 20-40 nm spherical AuNPs, their sensitivity low, which greatly limits wide application AuNP-based LFIA. With rapid advances in materials science and nanotechnology, synthesis noble metal (NMNPs) has enhanced physicochemical properties such optical, plasmonic, catalytic, multifunctional activity by simply engineering physical parameters, including size, shape, composition, external structure. Using these engineered NMNPs an alternative to LFIA been significantly improved, thereby expanding working range scenarios LFIA, particularly trace analysis. Therefore, this review, we will focus on design demonstration improving We highlight strategies available for tailoring NMNP designs, effect performance, principle each enhancing Finally, current challenges future improvements field are briefly discussed.
