Recent development of biomass derived carbon dots in fluorescent sensing applications

Carbon dots (CDs) are flexible and promising family of nanomaterials that have gained attention due to the rapidly developing field of nanotechnology. The biomass derived carbon dots (BCDs) are sustainable materials obeying green chemistry principles and are derived from abundant and renewable natural resources. Due to modern industrialization, waste generated and disposed to the environment causes pollution which in turn has negative effects on human and animal life. It is crucial to build sensor systems that can detect contaminants and helps in controlling water pollution. In this context, fluorescent BCDs are appropriate sensor materials due to their outstanding selectivity and sensitivity for recognizing analytes, providing an efficient and reliable method for monitoring the environment as compared to other techniques. This work presents the recent advancement of eco-friendly BCDs from natural sources with remarkable fluorescence properties and its application in detection of different analytes.
