Theoretical Comparison of Optical and Photothermal Properties of Near-Infrared Plasmonic Nanoparticles

Liu K., Xue X., Furlani E.P., University at Buffalo, US

In this presentation, we use 3D computational models to compare the optical and photothermal behavior of plasmonic nanostructures that are commonly used for near-infrared (NIR) applications. These include SiO2@Au core-shell, Au nanocage and Au nanorod [...]

Self-Assembly and Optical Behavior of Magnetic-Plasmonic Nanostructures

Liu K., Xue X., Sukhotskiy V., Furlani E.P., University at Buffalo, US

We introduce a bottom-up method for the fabrication of nanostructured photonic media and demonstrate proof-of-principle using a multiphysics modeling approach. The method involves magnetic field-directed self-assembly of magnetic-plasmonic core-shell particles (e.g. Fe3O4@Au) into extended particle [...]

Computational Analysis of Electrical Stimulation Devices to Promote Wound Healing

Anand A., Liu K., Sukhotskiy V., Verma A., Fournier J., Gellman G., Bacon W., Furlani E.P., University at Buffalo, Garwood Medical Devices, LLC, US

The treatment of wounds is a fundamental and major challenge in health care. Chronic wounds (e.g. diabetic) are particularly problematic and pervasive, afflicting approximately 6 million patients in the US alone at an annual cost [...]

Field-directed Self-assembly of Multifunctional Magnetic-Plasmonic Core-shell Nanoparticles with Applications to Photonics

Xue X., Liu K., Wang J., Furlani E.P., University at Buffalo (SUNY), US

Interest in the manipulation and self-assembly of magnetic nanoparticles has grown in recent years due to advances in particle synthesis and functionalization, which have led to a proliferation of applications that include the biomolecular transport, [...]

Plasmonic Nanocages as Photothermal Transducers for Nanobubble Cancer Therapy

Karampelas I.H., Liu K., Furlani E.P., University at Buffalo (SUNY), US

The ability to generate and control thermal energy with nanoscale resolution is finding increasing use in a variety of applications spanning the fields of nanoparticle synthesis, nanofabrication, bio-imaging and medical therapy [1, 2]. One of [...]

Coupling of CdSe/ZnS quantum dots: among themselves and with matrices

Liu K., Tsu R., University of North Carolina at Charlotte, US

We investigate the photoluminescence (PL) properties of CdSe/ZnS QDs deposited on Si, fused silica, Au film, and silica nanospheres. The red shifts of the PL peak were observed with increasing density of QDs on various [...]
