Magnetic Responsive Hydrogel Material Delivery System

Magnetic nanoparticles can be used as contrasting agents in MRIs, and as a drug delivery mechanism.

Interest in the design of new drug delivery systems focuses on releasing the drug at a controlled rate and desired time. Magnetic nanoparticles (MNPs) have shown great potential for use in biomedicine due to their ability to get close to biological entities such as cells, viruses, proteins, and genes with heating ability when exposed to a time-varying magnetic field. Superparamagnetic MNPs with proven biocompatibility have attracted attention as drug carriers in hyperthermia therapy, magnetic resonance imaging (MRI) as a contrasting agent, tissue repair, immunoassay, and cell separation procedures.

Boosting Nanowires for Better Batteries and Solar Cells

Stanford University engineers have found a novel method for "decorating" nanowires with chains of tiny particles to increase their electrical and catalytic performance. The technique is simpler and faster than earlier methods and could lead to better lithium-ion batteries, more efficient thin-film solar cells, and improved catalysts that yield new synthetic fuels.

Nanotrees Turn Sunshine into Hydrogen Fuel

University of California, San Diego electrical engineers are building a forest of tiny nanowire trees in order to cleanly capture solar energy and harvest it for hydrogen fuel generation. Nanowires, which are made from abundant natural materials like silicon and zinc oxide, offer a cheap way to deliver hydrogen fuel on a mass scale.

Welding Nanowires With Light

Electrically conductive meshes made of metal nanowires promise exceptional electrical throughput, low cost, and easy processing in applications like video displays, LEDs, and thin-film solar cells. However, in processing, these meshes must be heated or pressed to unite the crisscross pattern of nanowires that form the mesh - damaging them in the process.

Die Extrusion Technology for Medical Tubing Applications

Patent-pending process would allow 1000-plus layers from a single extruder.

Although the concept of nanotechnology (controlling matter on an atomic scale) dates back to 1959, it is only now becoming more commercially realized. It has the potential to challenge the way all products are extruded in almost every type of medical tubular or related industrial product applications.
