Special Issue Information

Dear Colleagues,

Nanoparticles are an attractive material in the fields of medicine, bioengineering, mechanical engineering, and chemistry due to their unique optical and thermal properties. Nanoparticles can be prepared by liquid-phase reduction methods with low costs, but the control of size distribution and efficient production process are important issues in these fields. To meet this demand, the synthesis of nanoparticles by microfluidic devices is attracting attention. A microfluidic device is a device with microchannel and laminar flows in the microchannel and diffusion of phase flow in the direction of channel width mix reagents. The synthesis of nanoparticles by the device is a slow process compared to that in turbulent flows. On the other hand, this synthesis can be applied to mass production by numbering up methods using many devices. Therefore, the fabrication process of the device, design of the channel pattern, and operation of the device for the efficient process are important tasks. 

The current Special Issue covers synthesis results of nanoparticles, the fabrication technique, design of microchannel patterns of microfluidic devices, application of nanoparticles, and simulation of fluid flow in microchannels in various microfluidic devices and micromixers.

In this study, a micropowder blasting system with varying processing temperatures was proposed to control the cross-sectional shape of a channel processed on a glass substrate. Based on an analysis of the processing temperature-dependence of the dynamic viscoelastic properties of a commercial mask material for micropowder blasting, a processing temperature control system that can be installed in a micropowder blasting machine was designed. The erosion of the mask during micropowder blasting depended on the loss tangent in dynamic viscoelasticity, and showed a maximum value at a processing temperature of 100 °C. Moreover, we confirmed that the maximum decrease in the width of the processed microchannel was 30 µm (12%) by mask erosion, and this change was large compared with the maximum change in the thickness of the eroded mask. These results clarified that varying the processing temperature using a mask could control the cross-section of the processed line pattern profile on glass, and a small-width channel was realized at a processing temperature of 109 °C.
