Research Of Ion Transport In Nanofluidic Channels Far From Equilibrium

At home and abroad, for flow control is satisfied that the research tends to equilibrium, electrokinetic phenomena for which the study of non-equilibrium state is rarely mentioned. In this paper, which started on the nano-channels, as well as the impact of energy conversion factors.A new method of diffusion-limited patterning (DLP) that exploits the high surface area-tovolume ratio in nanofluidic channels was developed. This technique is self-aligning and is simple to implement for patterning multiple species. DLP was demonstrated by patterning alternating bands of fluorescently labeled and unlabeled streptavidin in biotinfunctionalized nanofluidic channels. A theoretical analysis was developed to describe pattern formation and resolution.Theoretical modeling of ionic distribution and transport in a nanochannel containing a surface charge on its wall,30 nm high and 5μm long,suggests that ionic current can be controlled by locally modifying the surface charge density through a gate electrode,even if the electrical double layers are not overlapped. When the surface charge densities at the right and left halves of a channel are the same absolute value but of different signs.In this paper, the discussion of a simplified three-dimensional model based on the use of matlab simulation,on the electric potential,ion concentration,pressure curves and the non-equilibrium flow is satisfied under the control of ion channel transport theory applied to give the introduction.This thesis focuses on exploration of phenomena that arise in nanofluidic channels with the aim of developing fluidic devices with new functionalities that are not accessible to microfluidics.Patteming of molecules or surface properties inside nanofluidic channels is important for flow control and integration of different functions in a single device.
