MoS₂-quantum dot triggered reactive oxygen species generation and depletion: responsible for enhanced chemiluminescence

Abstract

Activated MoS2-QDs exhibit a promising capability for the generation of reactive oxygen species.

Quantum dots‐based chemiluminescence probes: an overview

“…Lin's group discovered that MoS 2 QDs exhibited a promising capability to generate ROS ( • O 2− , • OH and 1 O 2 ) in alkaline solution . The rapid reaction of MoS 2 QDs with • O 2− and • OH 1 O 2 produced electron‐injection (MoS 2 QDs) •− and hole‐injection (MoS 2 QDs) •+ species, respectively.…”

One‐step synthesis of cationic gold nanoclusters with high catalytic activity on luminol chemiluminescence reaction

“…have been reported to enhance CL reactions. [ 15–25 ] Metal nanoclusters (NCs) are composed of several to dozens of metal atoms, and commonly have an ultra‐small size of < 2 nm. [ 26 ] Compared with metal nanoparticles, metal nanoclusters are smaller in size and have a larger specific surface area.…”

Ultra-Weak Chemiluminescence Enhanced by Cerium-Doped LaF3 Nanoparticles: A Potential Nitrite Analysis Method

“…Nitrogen-rich quantum dots (QDs) were facilely synthesized and intensely enhanced the ultra-weak CL reaction of the NaIO 4 -H 2 O 2 system through electron hole injection and CL resonance energy transfer (Zheng et al, 2017 ). In particular, molybdenum sulfide QDs were proved to give rise to the generation of reactive oxygen species from hydrogen peroxide (H 2 O 2 ) in alkaline solution and gave a promise for CL emission (Dou et al, 2019 ). However, fluoride-based nanomaterials were scarcely utilized and the developed CL analysis was rarely applied in nitrite detection.…”
