Carbon dots (Cdots) exhibit remarkable physico-chemical properties, and have been employed in diverse optical, electronic, and biological applications. In this presentation I will present some of our recent studies in which we demonstrated interesting environmentally oriented applications of Cdot systems. Specifically, I will present an <b><i>artificial nose</i></b> for sensing and distinguishing vapor molecules, based upon recording the capacitance of interdigitated electrodes (IDEs) coated with Cdots exhibiting different polarities. The capacitive C-dot-IDE sensor was employed to continuously monitor microbial proliferation, discriminating among bacteria through detection of distinctive “volatile compound fingerprint” for each bacterial species. Different research projects I will discuss have focused on the construction of Cdot-hydrogel composites for sunlight-mediated water purification and oil-spill cleaning. These applications are based upon exploiting the photothermal properties of the Cdots.
