Quick extracellular biosynthesis of low-cadmium Zn_xCd_1−xS quantum dots with full-visible-region tuneable high fluorescence and its application potential assessment in cell imaging

Abstract

The biosynthesis of metal nanoparticles/QDs has been universally recognized as environmentally sound and energy-saving, generating less pollution and having good biocompatibility, which is most needed in biological and medical fields.

Advances in electrochemiluminescence for single-cell analysis

“…[73][74][75] With homogeneous and core-shell structures for easy surface modification and confined sizes at the nanoscale (1-10 nm) for better quantum confinement effects, metal QDs are widely used in bioanalyses such as molecular detection and cell imaging. [76][77][78] CDs (including graphene dots) are promising ECL luminophores used in bioanalysis due to their good stability, ease of modification and biocompatibility. [79][80][81] However, conventional CDs exhibit weak ECL emission and require high excitation potentials, which limit their sensitivity and safety.…”

Ultraprecise control over the photophysical properties of novel amino acid functionalized CdTeS quantum dots and their effect on the emission of yellow-emissive carbon dots

“…16–24 Researchers are very intrigued by developments in ternary/quaternary quantum dots as control over the composition of ternary/quaternary quantum dots allows researchers to control the photophysical properties of quantum dots with a different approach in addition to controlling the photophysical properties by controlling the size of the quantum dots. 16–24 Therefore, developing user-friendly and easy methods to synthesize composition controllable ternary/quaternary quantum dots has become an interesting challenge. 16–24…”
