Abstract

There has been an increasing use of quantum dots for various applications in recent years. In this talk, author will be focusing on the use of quantum dots as counter electrodes in dye-sensitized solar cells (DSSCs) and as bioimaging and possible cancer treatment. In DSSCs, the use of Pt is still widely used as counter electrodes (CE) owing to its high catalytic efficiency and stability but the downside is its cost. In this regard, we synthesized a tri-doped natural carbon dots as an alternative CE in DSSCs. We assessed different metal ions with ethylenediamine and sulfur powder as additives. We also applied sulfur-limonene polysulfide as substrate for our quantum dots. All our results showed efficiency very close to the Pt electrodes which could be used as low-cost CE alternatives. Water-soluble fluorescent carbon-dots derived from natural sources having a particle size <2 nm were used as possible bioimaging agent and cancer treatment. Various characterization data and possible new approach in the stimulation of ARF-mediated signaling to inhibit nuclear YAP using nanomaterials will be discussed. Recent Publications 1.
