ABSTRACT
In the current scenario, the promising physicochemical properties of carbon dots (C-dots) have displayed a colossal range of potential applications in the area of biomedicine. Differently from the available conventional types of dyes with low-range stability and toxic nature, carbon dots possess superior biocompatibility with high-range thermal stability and have successfully been utilized for in vivo and in vitro imaging. The present chapter will highlight the latest research on the fabrication of carbon dots by using natural resources. The structural, optical, and fluorescence properties of carbon dots will be discussed in detail, in addition to the potential roles of carbon dots in bioimaging with special emphasis on the in vivo imaging of cancerous cells. The existing challenges being faced and the future prospects in this fast developing area of research are anticipated to provide an essential impetus for motivating innovative discoveries on carbon dots both from the elementary and the realistic perspectives.
