In recent years, surface acoustic wave (SAW) devices have demonstrated great potentials and increasing applications in the manipulation of nano- micro-particles including biological cells with advantages label-free, high sensitivity accuracy. this letter, we introduce a novel tilted-angle SAW to optimise pressure inside microchannel for cancer-cell manipulation. The generation radiation force a...

This paper describes a simple technique for patterning channels on elastomeric substrates, at two distinct scales of depth, through the use of controlled fracture. Control of channel depth is achieved by the careful use of different layers of PDMS, where the thickness and material properties of each layer, as well as the position of the layers relative to one another, dictate the depth of the c...

Abstract Recently, there has been much interest in applying the color changes of nano-patterned structures to sensor technology. However, lithographic nano-patterning process is not environmentally friendly, and it difficult fabricate large areas due limitations associated with this approach. In study, we realized a highly tunable structural coloration based on Fabry–Perot interferometer design...

We introduce a new class of photo-electron-beam resists and solvents which are benign to organic electronic materials. We demonstrate that our patterning approach enables the fabrication of unique organic electronic devices, such as all organic thin film transistors, patterned light emitting diode displays and top-contact small channel length thin film transistors. Summary of Research: Organic ...

Theoretical analysis and Computer simulations have proven to be cost-effective and powerful tools in scientific studies of materials, particularly at nano-scale where synthesis of nano-structures, interpretation of their observed character and exploration of new structures are not always straight forward. We present here fundamental principles of techniques used today for computational simulati...

Trichome patterning in Arabidopsis serves as a model system to study how single cells are selected within a field of initially equivalent cells. Current models explain this pattern by an activator-inhibitor feedback loop. Here, we report that also a newly discovered mechanism is involved by which patterning is governed by the removal of the trichome-promoting factor TRANSPARENT TESTA GLABRA1 (T...
