This review presents the last advances related to analytical and bioanalytical applications of electrochemiluminescence (ECL) achieved by exploiting the special optical or electrochemical properties of quantum dots and nanoelectrodes, respectively. After a brief introduction which covers the basic concepts of ECL detection, the review presents relevant examples dealing with in the use of quantum dots and arrays of nanoelectrodes to improve the analytical and bioanalytical capabilities of ECL. Finally, prospects and limits derived from the application of the above advanced nanomaterials to stimulate ECL emission are discussed.read more

TL;DR: A mechanistic study indicates that ECL is mainly generated due to the high electron affinity of siloles and restriction of the intramolecular motions caused by their propeller-like noncoplanar structures, and this system realizes the sensing of organic-based ECL in the water phase by solving the crucial problems of water insolubility and aggregation-caused quenching.

Probing the Cytotoxicity Of Semiconductor Quantum Dots.
TL;DR: This work found that CdSe-core QDs were indeed acutely toxic under certain conditions and modulated by processing parameters during synthesis, exposure to ultraviolet light, and surface coatings, and suggests that cytotoxicity correlates with the liberation of free Cd2+ ions due to deterioration of the Cd Se lattice.
