In this research work, author has presented a short review on nanofluidics. Total three individual microchannel bends as microfluidic devices are designed, fabricated and tested in this experimental work using author’s own hands-on completely. Polymethylmethacrylate (PMMA) is the selected polymeric material to fabricate these microfluidic devices. Dyed water is prepared as working liquid to test these microfluidic devices. According to this experimental study, the surface-driven microfluidic flow of dyed water is faster in the microchannel of higher channel aspect ratio inside the microchannel bends. The surface-driven microfluidic flow of dyed water is faster due to the effect of centrifugal force inside the microchannel bends. This experimental work may be useful to develop the nanofluidic devices and systems in future by an experimental transition from microfluidics to nanofluidics.

This review summarized recent progress in synthetic chemistry in microchannel reactor, in which the feature of microchannel reactor itself and variety of reactions in microchannel reactor were presented. There is a basic difference between fluidic system in batch scale and that in microchannel which is caused by difference of those geometry. First, solution forms laminar flow in microchannel. Second, short diameter of microchannel enhances the efficiency of transport of mass and heat. Recent reports revealed that microchannel reactor is not only feasible tool for a safe and highly efficient reaction, also feasible tool for highly stereo-controlled or rapid reactions.

Abstract A two‐step microreactor for the investigation of glucose oxidation is presented. A model is created to pre‐judge the changes in concentrations of the reactants in the straight channels of the microreactor. The structure of the rapid mixing‐reaction units of the microreactor was optimized, and the optimal parameters were found to be p = 1:3, r = 1:1, and w s = 60 μm. The model and the optimization method can facilitate the design of microreactors.

We developed a simple immobilisation method for His-tagged enzymes on a microchannel surface. It facilitates immobilisation of protein molecule on microchannel surface through Ni-complex, using crude or purified protein solutions. By this method, we could immobilize proteins on microcapillary constantly. This method might be useful for further development of microreactor with reversibly immobilized enzymes.

We fabricated polymer-based microchannel-microheater chips and applied the chip to a synthetic reaction to benzylidenemalononitrile (BMN), known as an anti-fouling agent. Under the optimum conditions, the BMN yield as high as 96% was attained with the reaction time of 84 s.

The combined problems of on-board hydrogen storage and the lack of hydrogen infrastructure impede the development of fuel cell-powered vehicles using hydrogen. Microreactors based on microchannel technology that generate hydrogen from liquid hydrocarbons are the best way to solve these problems. The principle of microreactors for hydrogen production is presented, and then the advanced microreactors based on microchannel technology are introduced in terms of four key techniques: microchannel structures, distribution of flow channels, sheet lamination structure, micromachining, providing the correlative design method. The prospect of microreactors for hydrogen production is discussed in the end.

Experiments were carried out in a slug flow microreactor to systematically investigate reaction behavior under variation of flow rate, and a comparative study was made. Y-junction microreactor and T-junction microreactor have been used to extract yttrium(III) using 2-ethylhexyl phosphonic acid mono-2-ethylhexyl (EHEHPA or P507). Results show that the maximum extraction efficiency of 90.4% in both microreactors could be achieved corresponding to the minimum flow rate of 10 and 100 μL/min. The values of specific interfacial area remain unchanged with the increase of flow rate, and the specific interfacial area of the Y-junction serpentine microreactor is much higher than that of the T-junction microreactor. Maximum values of volumetric mass-transfer coefficient (1.642 s–1) in the Y-junction microreactor are found to be several orders of magnitude higher than those of the T-junction microchannel (0.043 s–1) and conventional extractors (0.0197 s–1).
