In Situ Shape Control of Thermoplasmonic Gold Nanostars on Oxide Substrates for Hyperthermia-Mediated Cell Detachment
Gail A. Vinnacombe-Willson
I am a PhD candidate in Materials Chemistry co-mentored by Prof. Paul S. Weiss (Chemistry & Biochemistry) and Dr. Steven J. Jonas (Pediatrics). My thesis project develops bottom-up synthesis, self-assembly, and soft-lithography for the scalable and precise functionalization of substrates with size- and shape-controlled plasmonic gold nanoparticles.

We developed a bottom-up wet chemical synthesis for generating plasmonic gold nanostars directly on the internal walls of microfluidic capillaries. The nanostars efficiently convert light to heat, which was leveraged to probe and selectively release individual cells grafted on the nanostar-coated surface.
ALMS state-of-the-art instrumentation, such as the SP8-MP-DIVE-FLIM, enabled us to trigger and monitor plasmonic heating of the nanostructures while simultaneously acquiring high-quality fluorescence confocal microscopy images of adherent cells. The highly experienced professional staff at ALMS assisted us through the design of the experiments and the customization of the setup.
Leica Deep In Vivo Explorer SP8 DIVE
The SP8 DIVE Deep In Vivo Explorer is the first spectrally tunable solution for multicolor, multiphoton (MP) imaging.
The SP8 DIVE provides spectral freedom. Equipped with 4Tune, a tunable, non-descanned detection system, the SP8 DIVE offers you unlimited flexibility and enables you to develop new multicolor deep in vivo experiments.
The SP8 DIVE provides maximum penetration depth. The new Vario Beam Expander can be tuned for improved penetration depth depending on the animal model. Capture twice as much of the fluorescence signal with the 4Tune detection. Achieve more contrast and depth for multicolor, deep in vivo imaging.
