Nanoparticles/Nanopowder For Drug Delivery: Silicon Nanoparticles/Nanopowder!

Drug delivery technology has received considerable attention in the past few years in the field of biomedical nanotechnology. Drug delivery implies that the approaches, technologies, process and systems for transporting a pharmaceutical compound in the body as needed. Drug delivery system is related with the quality, quantity and duration of drug presence. It is also concerned with scientific site of pharmaceutical compounds within the body. That means proper drug delivery system must transport pharmaceutical compounds with proper quantity into the accurate sites of the body. Drug delivery is often approached via a drug's chemical formulation, but it may also involve medical devices or drug-device combination products.
Silicon (Si) is a biomaterial, one of the most frequent elements in the earth’s crust. A range of methods can be applied for the fabrication of porous Si, such as chemical stain etching, chemical vapor etching, laser-induced etching, metal-assisted etching, spark processing and reactive ion (plasma) etching. Porous Silicon nanoparticles/nanopowder can be seen as one of the attractive materials for controlled drug delivery applications. Porous Silicon nanoparticles/nanopowder have been established as excellent candidates for medical applications as drug delivery devices, due to their excellent biocompatibility, biodegradability, and high surface area. Also there are some other several important properties of porous silicon nanoparticles/nanopowder such as controllable pore sizes and volumes, optical properties, usage as a template for organic and biopolymers.
It is possible to make some modifications on porous Si surfaces that can be used to control the amount, identity and in vivo release rate of drug payloads. Furthermore, there are some well-established methods of fabrication for possible users which can be customized to control the pore size, chemical modification of silicon surfaces and the characterization and pore morphology of silicon structures.
Porous Silicon nanoparticles/nanopowder can be used in not only drug delivery, but also microfluidics, microarray biosensors and high-resolution imaging techniques that can provide detailed images of cancerous cells and lesions, thus these nanoparticles/nanopowder are creating systems with incredible synergetic capabilities for therapeutic and diagnosis applications.

Titanium Carbide Powders and Applications

Titanium carbide which has the chemical formula of TiC attracted great interest for many structural applications due to its extremely high melting temperature, high hardness, high chemical resistance and good electrical conductivity. Therefore titanium carbide can be used in cutting tools, grinding wheels, wear-resistant coatings, high temperature heat exchangers, magnetic recording heads, turbine engine seals, and bullet-proof vests, etc. In addition, a promising field of application comprises plasma and flame spraying processes in air, where titanium carbide-based powders show high-phase stability. TiC(Titanium Carbide Powder) (325 mesh, 99,9+%)  can also be used in biomedical implant devices. Materials used for biomedical implant devices must satisfy a variety of property demands, which are often mutually exclusive. Further, different parts of a device demand different material properties. These factors often make it difficult to manufacture a medical device using a...

New Way of Deaf-Mute Communication with 3D Graphene

Image retrieved from: http://blogs.rsc.org/cc/2016/09/01/3d-graphene-adds-dimension-to-deaf%E2%80%93mute-communication/ Chinese scientists have developed wearable electronic device with conductive 3D graphene structure to translate sign language into written text. This technology can be applied by injecting graphene ink from a syringe under printed electronic field. For medical field, such as adhesive patches which determine heart, brain signal and neural activity, wearable and bio-integrated medical devices are very important. Due to noticeable properties of cast graphene, for example a 2D honeycomb lattice, excellent mechanical and electrical behaviors, Graphene has an important material in warble technology. However, it is difficult to preserve advantages of Graphene material in a 3D material which has an information about forces from every angle. Yanlin Song  and co-workers at the University of the Chinese Academy of Sciences, Beijing, and Shenyang Jianzhu University...

Carbon Nanotubes Doped with Graphene Nanopowder and Applications

Carbon nanotubes and graphene are different forms of carbon atom based materials. They have different properties and can be used in various applications. But what happens if we use them as a hybrid structure? The excellent mechanical, physical, and chemical properties of low-dimensional carbon materials like graphene and carbon nanotube have enabled them as promising building blocks for three-dimensional nanoarchitectures. In this regard, extensive interests have been attracted to synthesize graphene and carbon nanotube hybrid structures. Earlier works suggested that  Carbon Nanotubes Doped with Graphene Nanopowder (52 wt% Graphene )  is a promising solution for quick energy dissipation, which could enhance interface thermal conductivity of the ‘building blocks’ for future nanoscale mechanical and electrical devices. In the electricity perspective, it is found that ‘CNT pillared-graphene’ system would extend the excellent electrical conductivity of graphene and nanotube to ...
