QDs can be modulated the emission wavelength and intensity, so they have possible application as
switch probes for cellular and whole-body imaging, optical modulators, and light emitting diodes.
We synthesize various types of NPs, including core/shell QDs, nanorods, nanotetrapod and nanoporous
materials.In our previous study, QD conjugate was photomodulated by additional UV excitations that
induce the electron transfers to QDs and quench their photoluminescence. And QD-sensitized solar cells were fabricated, using the inorganic capping ligands-QDs.
Metals can display Surface Plasmon Resonance when their sizes are reduced to the nanoscale.
The applications of noble metal NPs can be very diverse such as spectroscopic and imaging tools,
because plasmon resonance properties can be tailored by choosing metals with appropriate dielectric
properties, and by selecting the size, shape, local environment of nanoscale metallic structures.
We proposed the novel metal NP complexes that could be used for highly-efficient cancer therapy and
for photoacoustic guided drug delivery.
QDs promise present a possible new technology for in vivo bio-imaging and future medical imaging
applications. QDs have proven potential as imaging contrast agents due to their bright luminescence,
their resistance against to photobleaching, and their tunable emission wavelengths. We developed NIR-II emitting QD probes, cancer diagnosis using QD-Antibody conjugates. Also we showed QDs in an
amphiphilic polyethyleneimine derivative platform for cellular labeling, targeting, gene delivery,
and ratiometric oxygen sensing.
