Attempts to neutralise basic fibroblast growth factor (BFGF) have met some success in blocking neovascularisation. The authors describe an oral protein vaccine based on human BFGF encapsulated poly(ε-caprolactone)εpoly(ethylene glycol)εpoly(ε-caprolactone) (PCEC) nanoparticles. The human BFGF encapsulated PCEC nanoparticles (BFGF/PCEC) were monodisperse with the mean diameter of 142εnm and can slow-released...
This paper describes the assembly of 2 nm gold nanoparticles between micro-fabricated planar electrodes by using dielectrophoresis (DEP). The optimal conditions for effectively dieletrophoretic manipulation have been established through theoretical analysis and experimental validation. In the theoretical analysis, the effect of Brownian motion was taken into consideration, as well as the electrothermal...
We demonstrate detection and sizing of single nanoparticles down to 30 nm by monitoring the mode splitting induced by a nanoparticle in an ultra-high quality factor (UHQ) microtoroid. Theory and methods are discussed.
We experimentally demonstrate that a single nanoparticle can induce mode splitting of MHz in an ultra-high-Q microtoroid resonator, which can be used to extract information of the nanoparticle. Analytical model matches well with the experiments.
Experimental results on varying particle size and dielectrophoretic (DEP) parameters, including voltage and frequency, are reported in this paper for investigating their effect on Au nano-particles Pearl Chain Formation (PCF). PCF was observed from 10 kHz to 5 MHz for 100nm gold Nano-particles (NPs), and 100 kHz to 10 MHz for 10 nm gold NPs. Variations in formation rate were detected when the applied...
