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 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...
Present study examines the flow characteristics of open microchannels with sharp turns by experimental and numerical methods. For the open channel system in microscale, the flow is mainly driven by surface tension at atmospheric pressure. The open channels are of various aspect ratios of depth-to-width, ranging from 0.75 to 3, and of turning angles from 45° to 135°. It is found that the turning angle...
