TL;DR: By combining selective Gram-positive bacterial recognition, super-resolution imaging, and exceptional antibacterial activity into a single system, the quaternized CDs represent a novel kind of metal-free nanoparticle-based antibiotics for antibacterial application and a new type of reagent for efficient bacterial differentiation.

TL;DR: A simple and highly efficient method for dopamine (DA) detection using water-soluble silicon nanoparticles (SiNPs) was reported, with a detection limit of 0.3 nM, which is the lowest limit reported so far.

TL;DR: The present work represents the first example that successfully turns fluorescent SiNPs into metal‐free NP‐based antibiotics with simultaneous bacterial imaging and killing capability, which broadens the applications of fluorescentSiNPs and advances the development of novel antibacterial agents.

TL;DR: In this article, a one-pot solvothermal method was developed to prepare a novel type of quaternized CDs using two commercial reagents (glycerol and dimethyl octadecyl[3-(trimethoxysilyl)propy]ammonium chloride, abbreviated as Si-QAC).

TL;DR: It is expected that the ultrasmall OSiNDs with superior fluorescence properties and easily modifiable surfaces could be applied as fluorescent nanoprobes, light-emitting diode phosphor, and anticounterfeiting material, which should be able to promote the preparation and application of silicon-containing nanomaterials.
