Abstract

original image

C-dots on hand: Luminescent carbon nanodots were synthesized and were shown to be biocompatible, have low toxicity, and distinctive photoluminescence properties. These C-dots are inexpensive to synthesize and could potentially be used for versatile applications, such as anticounterfeiting, information encryption, and information storage.
