Imaging and manipulating organometallic molecules by scanning tunneling microscopy
Using scanning tunneling microscopy (STM) we have explored complex surface adsorbed molecules, nanocars, on Au(111) and the parameters related to the direct translation of these molecules by the STM tip. Specifically, the ...
Mie and Finite-Element Simulations of the Optical and Plasmonic Properties of Micro- and Nanostructures
A Mie-based code is developed for multilayer concentric spheres. The code is used in conjunction with a finite-element package to investigate the plasmonic and optical properties of micro- and nanostructures. For plasmonic ...
Plasmonic Manipulation of Light for Sensing and Photovoltaic Applications
Plasmonics is a successful new field of science and technology that exploits the exclusive optical properties of metallic nanostructures to manipulate and concentrate light at nano-meter length scales. When light hits the ...
Water-phase synthesis of cationic silica/polyamine nanoparticles
Functionalizing surfaces with amine groups through the hydrolytic condensation of aminotrialkoxysilanes is a typical approach when modifying silica particles for use in bioimaging, enzyme immobilization, and other applications. ...
Bilayer Approaches for Nanoparticle Phase Transfer
Nanoparticles (NPs) are often synthesized in organic solvents due to advantages of superior size and shape control obtainable in a non-polar environment. However, many applications featuring NPs require them to be in aqueous ...
Optical Properties of Strongly Coupled Plasmon-Exciton Hybrid Nanostructures
Strongly coupled plasmon-exciton hybrid nanostructures are fabricated and their optical properties are studied. The plasmonic and excitonic systems are gold nanoshells and J-aggregates, respectively. Gold nanoshells are ...
