One-Step Synthesis of Water-Soluble Silver Sulfide Quantum Dots and Their Application to Bioimaging.


ABSTRACT: This work reports a simple water-phase microwave method for the synthesis of water-soluble red emission Ag2S quantum dots at low temperatures without the need for an anaerobic process. It is worth noting that the prepared water-soluble Ag2S quantum dots enjoy positive water dispersion stability. 3-(4,5)-Dimethylthiahiazo(-z-y1)-3,5-di-phenytetrazoliumromide (MTT) results showed that the prepared Ag2S quantum dots had promising biocompatibility and low cytotoxicity. In addition, we further applied the low-toxicity near-infrared Ag2S quantum dots for cell imaging, demonstrating a promising biological probe for cell imaging.
