Rapidly detecting antibiotics with magnetic nanoparticle coated CdTe quantum dots.

A reusable magnetic-quantum dot material (MNP-SiO2-QD) with good magnetic properties and high fluorescence retention was successfully fabricated from linked magnetic nanoparticles and quantum dots. The resulting material can qualitatively and quantitatively detect four kinds of antibiotics and maintain high recovery rates.

An improvement in scanning electrochemical microscopy based on a plasmon-accelerated electrochemical reaction.

We demonstrate an approach using a plasmon-accelerated electrochemical reaction to improve the performance of scanning electrochemical microscopy.
