Electrochemically deposited metal nanoparticles for enhancing the performance of microfluidic MEMS in biochemical analysis

Abstract: The fabrication and evaluation of the analytical performance of integrated microfluidic MEMS modified with electrochemically deposited metal nanoparticles are described in this paper. The microfluidic MEMS is a hydride system that comprise two layers, poly-dimethylsiloxane (PDMS) and glass, which in turn enclose a micro channels network and a set of 15 micro electrodes, respectively. The mechanism of electrokinetic phenomenon and electrochemical detection were applied for performing injection and separation, and sensing the components of a biochemical mixture, respectively. The technique of electrochemical deposition was employed for depositing nanoparticles of gold, palladium and platinum on the surface of integrated microelectrodes. The nanoparticles-modified micro electrodes were characterised electrochemically and using scanning electron microscope (SEM). Importantly, the nanoparticles-based decoupler has significantly enhanced the analytical performance of the microfluidic MEMS, where detection limits in the low nanomolar range were recorded for the targeted analytes.

Developed greener method based on MW implementation in manufacturing CNFs

Abstract: This study comes as the first trial that uses microwave (MW) in combination with assisted chemical vapour deposition (CVD) to generate homogeneous carbon nanofibers (CNFs) at short period thermal reaction. The outcomes confirmed that these materials are of highly-ordered pyrolitic graphite nature. CNFs were obtained having uniform diameters (80-150 nm) and long fibres (0.82-1.75 μm). SEM and TEM evaluations revealed relatively less damage in fractured surfaces and the TGA exhibited insignificant change of CNFs during thermal decomposition. The 'solid' CNFs showed clear properties as disorder, crystalline, and bent graphitic sheets. The as-prepared CNTs demonstrated good MW-absorption properties with superior performance which could be due to the combination of the dielectric-type absorption and the interference of multi-reflected MW. This enhancement gave 97% purity of the novel manufactured CNFs. Therefore, we recommend our greener nanoproducts for industries as energy, pharmaceutical, cosmetics, textile, sensors, electronics, vehicles, and both of quantum dots (QD) and fluorescent C-dots.

Review of nanomanipulators for nanomanufacturing

Abstract: This paper reviews the state-of-the-art of nanomanipulator concepts, designs and practices in research, prototyping and fabrication of nanodevices. Limitations of existing nanomanipulation systems in use have been examined including the device sizes of orders of magnitude too large for in situ applications and parallel applications in nanomanufacturing. Design strategies, mechanisms and practical solutions have been investigated for nanaomanipulation with multiple degrees of freedom, needed for manufacturing complex nanodevices and nanosystems. Both macro- and micro-scale nanomanipulator designs and practices are examined.

Micro-machining and micro-grinding with tools fabricated by micro electro-discharge machining

Abstract: This paper provides an overview of several approaches to micro-machining by mechanical and electro-discharge means of material removal. Two steps are required in machining micro features. Firstly, a custom-shaped tool is created from suitable stock. In many cases, this is carried out using a small-scale version of wire Electro-Discharge Machining (EDM) in tool materials such as sintered PolyCrystalline Diamond (PCD) or tungsten carbide. Then the micro-tool can be used as a miniature end mill, drill or abrasive wheel. Each of these mechanical machining methods can be combined with EDM to achieve a customisable surface finish and feature accuracy. Trade-offs such as tool wear, Material Removal Rate (MRR) and machining time are discussed in this paper within the context of several examples.

Micro and nano structuring and texturing of polymers using plasma processes: potential manufacturing applications

Abstract: We review our recent work on the deterministic (top down) micro/nano structuring and stochastic (random) micro/nano texturing of polymeric materials for a variety of applications. We create polymeric microfludics/microsystems using plasma processing as well as 'smart' polymer surfaces with controlled wetting and optical properties. First, fabrication of polymeric micro-nanosystems and microfluidics using standard photolithography followed by plasma etching is proposed as an alternative method for polymer microfabrication. Second, plasma induced polymer nanoroughening (nanotexturing) is proposed as an extremely attractive methodology to control the wetting properties of polymers and create superhydrophilic or hydrophobic or robust superhydrophobic polymer surfaces. These surfaces may in addition possess controlled optical properties, such as antireflectance combined with good transmittance. Third, ordered spontaneously formed structures are created on plasma processed polymers. Potential applications are discussed.
