Accurate size profiling on the physical sizes of aqueous nanoparticles and molecules may be affected by various factors such as the particle aggregation or the small molecular sizes. Thus, a nanoparticle exposure chamber system was constructed in which the aqueous nanoparticles are electrosprayed and dispersed into a controllable manner prior to be determined on their size distribution and concentration...
In this research, we present a chip based capillary electrochromatography (CEC) carrying out a highly efficient separation of biomolecules through gradient hydrophobic stationary phase (GHSP) provided by multiwalled carbon nanotubes (MWCNTs) nanocolumns. 4-azidoaniline was employed for the surface modification of the MWCNTs to form a gradient stationary phase by a photochemical reaction through a...
This paper presents a study of electrokinetic transport in a nano-fluidic chip that allows for the selection and pre-concentration of molecular mixtures by a high density multi-wall carbon nanotubes array (MCNTs) in nano-channels. Parylene (poly(p-xylylene)) was deposited on MWCNTs walls as a dielectric material, the surface charge characters and density could adjusted when an induced polarizes filed...
This paper proposes a novel design of a reusable biosensor for in-situ and continuous protein detection. The sensing probe was practiced by the integration of a fiber optic interferometry (FOI) sensor accommodated in a micro opto-fluidic chip covered with a microdialysis membrane and surface regeneration mechanism for regenerable detection. Gold-nanoparticles (GNPs) labeled anti-rabbit IgG was used...
This paper proposes a needle-type biosensor for immunological application, which combines the abilities of real-time monitoring, in-situ measurement and high sensitivity, by adopting gold-nanoparticles (GNPs) coated with antibody to enhance the signal of Fabry-Perot (F-P) interferometry in an optic fiber sensing system. Strong reflection induced by larger index mismatch and longer optical path from...
