here 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.
