Carbon dots


We employ carbon dots (nanoscale fluorescent carbonaceous nanoparticles) in varied applications, including chemo- and bio-sensing, cell imaging, optics, theranostics, and composite materials. Importantly, we have demonstrated that the carbon building blocks endow the produced materials with molecular recognition capabilities, obviating the need for post-synthesis modification of the carbon dots.
