pH Dependent Optical Properties of Surface Modified Gold Nanoparticles Using a Bovine Serum Albumin Coating

Xu Y., Linares K.A., Meehan K., Love B.J., Love N.G., Love B.J., Love N.G., Virginia Polytechnic Institute and State University, US

Use of gold nanoparticles has significant potential in biosensors. Gold’s surface plasmon resonance (SPR) is influenced by the refractive index of the surrounding environment. Changes in the SPR signal can be correlated to changes in [...]

Adsorption of Gold Atoms on Carbon Nanotubes

da Silva A.J.R., da Silva E.Z., Carrijo Faria J., da Silva A.J.R., da Silva E.Z., Fazzio A., Universidade de Sao Paulo, BR

We study in detail the adsorption of Au on single walled carbon nanotubes (SWCN). All our results are based on ab initio total energy Density Functional Theory calculations using numerical orbitals as basis sets. We [...]

Mechanical Property Measurement of Thin-film Gold Using Thermally Actuated Bimetallic Cantilever Beams

Pamula V.K., Jog A., Fair R.B., Duke University, US

We describe a method for estimating the Young's modulus of thin-film gold deposited on the poly2 layer in the MUMPS process is described. An optical detection system employing position sensitive detectors (PSD) is built to [...]
