Carbon Quantum Dots with Tunable Size and Fluorescence Intensity for Development of a Nano-biosensor.

ABSTRACT: Carbon quantum dots (CQDs) are a class of nanomaterials known for their remarkable photostability, chemical inertness and biocompatibility. Changing their size, structure, and surface chemistry enable the tuning of their luminescence property, which gives them tremendous potential for various applications. CQDs synthesis typically involves long tedious processes, requiring multiple steps and harsh reaction conditions. Here, a new reliable, economical, and ultra-rapid one-step fabrication method is introduced to obtain CQDs with well-defined and reproducible photoluminescence properties via a simple heat treatment. These solid-state CQDs are homogenous in size and are ready to use without the need for further purification. The size of the fabricated CQDs and their corresponding peak fluores
