Abstract:
During the last 20 years, different nanomaterials have been applied in
healthcare applications such as cancer imaging, lymph node mapping and
brain diseases therapy. These nanomaterials can be engineered to serve
as a platform for challenges in highly sensitive optical diagnostic
tools, biosensors, and guided imaging and therapy. Nanomaterials
surface can be decorated with functional biomolecules to selectively
target specific sites in vitro and in vivo.  Importantly, they possess
unique tunable spectral and optoelectronic properties, which have
significant advantages for various biological applications such as
tumor growth monitoring, single biomolecule detection, targeted drug
delivery therapy, and control release of gene silencing materials. The
flexibility and versatility of nanomaterials may provide the keys to
answer important biological questions and ultimately improve
diagnostics and therapy of human diseases. A synergistic combination
of nanomaterials with biophotonics provides unprecedented
opportunities to address many current challenges in disease diagnosis
and therapy. For example, quantum dots, gold nanoparticles, gold
nanorods, gold nanoshells, upconversion nanocrystals, iron oxide
nanoparticles, carbon nanotubes, carbon dots, silica nanoparticles,
aggregation-induced emission (AIE)-based nanoparticles, etc. are among
the commonly investigated nanomaterials in biophotonics. The
flexibility in optical and electronic tuning allows these
nanomaterials to emit or scatter from visible to near-infrared (NIR)
region, an essential characteristic for tailoring specific needs in
biophotonic applications. In this talk, we will highlight the use of
nanomaterials with different sizes, compositions, and shapes for
biophotonic and nanomedicine applications (e.g. guided bioimaging,
multimodal imaging, sensing, in vivo surgery, gene delivery, etc).
Also, we will discuss important factors on designing bioconjugated
nanomaterials for biophotonic applications as well as the future trend
of using nanomaterials in the biophotonic and nanomedicine field.
Certainly, the in vitro and in vivo nanotoxicity of nanomaterials will
be one of the main challenges to be overcome if we would like/want to
pursue in vivo biophotonic or nanomedicine technologies with
nanomaterials. The toxicity assessment of nanomaterials in cell
culture and animal models will be presented. This talk is intended to
promote the awareness of past and present developments of
nanomaterials in biomedical fields, the potential toxicity of
nanomaterials, and the approaches to engineer new types of safe
nanomaterials, whereby encouraging researchers to think about exciting
and promising biophotonic and nanomedicine applications with
nanomaterials in the near future.
