(71a) Microfluiding Activities in Artificial and Bio-Mmbrane

Along with development of nano-particles and bio-nano-technology and the support of genetic engineering, it is today we have developed additional concept for continuations of drug release, monitoring of different units, starting from chemical to biological system including the organ specific disease control with the help of nono-divices. To realize the process the relevant question was, how do you introduce the process in continuous mode. To describe the process and the concept of microfluiding activities in artificial and bio-membrane the concept of fluid, mass and heat transfer through capillary system must be studied and where the Reynolds should be less than < 30. In general micro fluid transport obeys the low Reynolds number Re = L.V.r/ m , where L denotes the length of tube, V the velocity, r as density and m as viscosity of fluid. Investigations of low-Reynolds number hydrodynamics naturally fall into the fluid dynamics realm of long interest to the chemical engineering and nano-biotechnology community. Gad-el-Hak, M (1999); Kim and Karrila, (1991) [1,2]. The fluid transport in microtubules is conceptualized by means of dragging, that the molecules maintain two fundamental criteria namely surface tensions of fluids and thermo dynamical equilibrium. However surface force play a more important role than the standard continuum of transport processes. So the molecular organizations of polymers and their charges on the surface of the molecules will take the major role to handle the movements and driving force of small fluid volumes through mico-nano-capillaries at small length scales. To compare the properties of micro fluiding activities changing from the range of macro-to micro- and nano-scale the following conditions are to be taken care;

1.The fluids must possess less inertia force compared to electrostatic/electrodynamic viscous or capillary effects.

2. The fluid must show the responsible molecular layering to control the local density fluctuations, to develop the slip length with non-linear shear rates at the junctions of capillary pores to convert non-Newtonian fluids to Newtonian fluids.

3. It develops a fluid nature by increasing diffusion velocities at the entrance of capillaries avoiding the clogging caused by O2 or some other means.

4. Smooth surface with less frictions and higher surface tensions could support the movements of fluidic activities to nono-microtubules.

5. Rheology of the fluid pays a significant role in manipulations and controlling of fluid flow.
