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 [...]

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, [...]

Bottom-up Nanofabrication of Crystalline Structures of Magnetic Nanoparticles

Xue X., Furlani E.P., SUNY at Buffalo, US

A bottom-up approach to the nanofabrication of three-dimensional (3D) crystalline structures of magnetic core-shell nanoparticles is presented. The approach is based on self-assembly and involves the use of soft-magnetic template elements to guide the assembly [...]

Microfluidics for multiplexing of core needle biopsies

Mojica W.D., Oh K.W., Lee H., Xue X., Furlani E.P., University at Buffalo, US

Image guided biopsies for the procurement of diagnostic tissue has proven to be safe, cost effective and useful. However, the amount of tissue obtained is often diminutive and may be exhausted for conventional diagnostic purposes. [...]
