Microfluidics and Nanofluidics

Mapping of transport parameters in complex pore spaces is of interest for many respects. Apart from classical porous materials such as rock, brick, paper and tissue, one can think of objects used in microsystem technology. Recent developments such as lab-on-a-chip devices require detailed knowledge of transport properties. More detailed information can be found in new journals such as Lab on a Chip [1] and Microfluidics and Nanofluidics [2], for example, devoted especially to this subject. Electrokinetic effects in microscopic pore spaces are discussed in Ref. [3].

Some preparation methods specific to the formation of nanoparticle suspensions are provided in References [20,62,63]. Many such methods are simply conventional colloidal suspension preparation methods that have been extended to produce smaller particle sizes, but others involve novel approaches. Some ofthese involve making nanoemulsions as a first step. For example, membrane, microfluidic and nanofluidic devices have been used to make nanoscale emulsions of all kinds, as already noted earlier, and the emulsion droplets so generated can be used in turn to make sohd microparticles and nanoparticles. If the nanoparticles are intended to encapsulate other materials, then a double emulsification technique can be used, at elevated temperature, to prepare a multiple emulsion (i.e.

Surface modification for microchannels in microfluidic and nanofluidic devices. 

The CVD method is an important method for the deposition of highly pure thin-layer films for microfluidic and nanofluidic devices. The most common use of CVD techniques in microfluidic and nanofluidic devices is for surface modification. With the rapid development in microfluidic... 

In the context of microfluidics and nanofluidics, demixing of fluid binary mixtures confined in narrow pores is a particularly relevant issue. An important facet of this behavior is that the concentration of such confined mixtures is typically rather inhomogeneous in the z-direction perpendicular to the walls of a pore, and the equiUbrium phase behavior due to the confinement which differs from that of the corresponding bulk mixture. The tmderstanding of these phenomena is a prerequisite for a discussion of demixing kinetics in pores or narrow chaimels. 

Microfluidic and nanofluidic chips have a wide range of applications in the chemical, biomedical, environmental, and biology areas, where a variety of chemical solutions are used. With the development of microfabrication technology, many new materials such as PDMS and poly (methyl methacrylate) (PMMA) are also employed for chip fabrication. Since each pair of sohd-liquid interface has its unique zeta potential and electroosmotic mobility, which have significant influences on flow control in such small-scale devices, it is very important to experimentally determine these two parameters using the current monitoring technique in order to develop microfluidic and nanofluidic devices for various applications.
