By enhancing the speed, accuracy, and sensitivity, it opens up a new possibility for direct analysis of biologically relevant entities such as nucleic acids and proteins in single cell level. Nanofluidic systems with critical dimensions which were comparable to the molecular scales can provide the aforementioned performance, offering a novel basis for ultrasensitive and high-resolution bio-detections...
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...
