Superhydrophobic poly(methylmethacrylate) (PMMA) surface with nanostructure was prepared effectively via phase separation and selective solvent method. It is proposed that the cooperation of the nanostructure of PMMA surface and the surface group reorientation leads to the superhydrophobicity of PMMA surface. The superhydrophobic PMMA surface with nanostructure was characterized by scanning ele...

The trend of integrating nanostructure to elevate the MEMS capability is becoming a trend in microelectronic sensor field. Critical functional element of sensors in the scale of 10 -6 and 10 -9 m in any dimension being incorporated with appropriate nanostructure as part of the sensor systems through two basic approaches: topdown and bottom up. The techniques and methods of both approaches will ...

Controlling biological molecular processes with light is of high interest in research and biomedicine, as allows precise selective activation a non-invasive non-toxic manner. A process benefitting from control the transport cargo across membranes, which conventionally achieved by membrane-puncturing barrel-shaped nanopores. Yet, there considerable to construct more complex gated pores. Here, we...

The most important experimental methods of studying the mechanical properties cells, as well common rheological models, among which discrete models micro/nanostructure cell and continuous that allow calculating modulus elasticity viscosity in normal pathological conditions are discussed. A review is given with an indication their features differences. new continuum model a multi-layer shell fil...

Introduction Perforation of maxillary sinus mucous membrane is of the most prevalent complication during open sinus lift surgery. Moreover, such complication can usually be managed by an absorbable membrane. As far as absorbable membranes are concerned, decellularized maxillary sinus mucous membranes, which is an extracellular matrix, can be used as a biologic scaffold and insulating membrane ...

Interfacial polymerization techniques offer a versatile route for microcapsule synthesis. We designed a microfluidic process to synthesize monodisperse polyurea microcapsules (PUMCs); the microcapsules are formed by an interfacial polymerization of isocyanate dissolved in the oil and an amine dissolved in water. We measure the mechanical properties of the capsule as well as transport properties...
