Although scientists have for decades been able to synthesize nanoparticles in the lab, the process is mostly trial and error, and how the formation actually takes place is obscure. However, a study re...
Mechanism of Hollow Nanoparticle Formation Due to Shape Fluctuations
Hollow Nanoparticle Formation Shape Fluctuations
2015/10/16
Shape fluctuations in nanoparticles strongly influence their stability. Here, we introduce a quantitative model of such shape fluctuations and apply this model to the important case of Pt-shell/transi...
Oscillatory optical response of amorphous plasmonic nanoparticle arrays
Oscillatory optical response amorphous plasmonic nanoparticle arrays Optics
2012/5/29
The optical response of metallic nanoparticle arrays is dominated by localized surface plasmon excitations and is the sum of individual particle contributions modified by inter-particle coupling depen...
A photonic crystal cavity-optical fiber tip nanoparticle sensor for biomedical applications
photonic crystal cavity-optical fiber tip nanoparticle sensor biomedical applications Optics
2012/4/19
We present a sensor capable of detecting solution-based nanoparticles using an optical fiber tip functionalized with a photonic crystal cavity. When sensor tips are retracted from a nanoparticle solut...
We report the fabrication of nanoparticle silver oxide thin films by rf magnetron sputtering and characterization of their nonlinear optical properties. The chemical decomposition and reversibility of...
Controlled Buckling and Crumpling of Nanoparticle-Coated Droplets
Controlled Buckling Crumpling of Nanoparticle-Coated Droplets
2010/11/24
We introduce a new experimental approach to study the structural transitions of large numbers
of nanoparticle-coated droplets as their volume is reduced. We use an emulsion system
where the disperse...
Substrate influence on the plasmonic response of nanoparticle clusters
Substrate the plasmonic response nanoparticle clusters
2010/11/16
The plasmonic response of nanoparticles is exploited in many subfields of science and engineering to enhance optical signals associated with probes of nanoscale and subnanoscale entities. We develop ...
Absence of scaling in transport through two-dimensional nanoparticle arrays
Absence of scaling two-dimensional nanoparticle arrays
2010/11/17
We analyze the transport in disordered two-dimensional nanoparticle arrays. We show that the
commonly used scaling hypothesis to fit the I-V curves does not describe the electronic transport in these...
Effect of particle size on nonlinear refractive index of Au nanoparticle in PVA solution
Nonlinear properties Z-scan technique nanoparticles
2010/6/30
Nonlinear refractive index of Au nanoparticle suspended in PVA solution was measured using a single beam Z-scan technique. Measurements were carried out using a green CW laser beam operated at 532 nm ...
The force acting on a polarizable nanoparticle in the quantized electromagnetic field
van der Waals interaction quantum friction nonequilibrium
2010/4/8
In this letter we derive an expression for the force acting on a small (still macroscopic) particle in the field of the quantized electromagnetic radiation in any arbitrary quantum state. This result ...

Au Nanoparticle Clusters: A New System to Model Hopping Conduction
nanoparticles Coulomb blockade hopping conduction
2010/4/12
We study electrical transport through self-assembled Au nanoparticle clusters which can be viewed as a new model system to study hopping transport. The physics of such systems is governed by two param...
