Smart magnetic hydrogels were investigated by researchers in Taiwan for the development of a new magnetically induced drug delivery system. By applying magnetic fields, they were able to switch the the drug release profile of the hydrogels between on and off mode.
In a rapidly growing field, electrospun biodegradable polymeric nanofibers are being used in scaffolds for engineering various tissues such as nerves, cartilages or bone. Recent research by scientists in Singapore offers new insights into the nanostructures and mechanical properties of single nanofibers.
It still is a huge challenge to treat neurodegenerative diseases such as Alzheimer, Parkinson or Huntington, which are increasingly affecting our society as the average life-span of our population increases. One of the main obstacles for successful therapy of these disorders is safe and effective drug delivery to the central nervous system.
Gold nanoparticles have shown promise for cancer therapy by virtue of their ability to absorb laser light, heat up and thus kill the tumor. However, in order for the gold nanoparticles to have their therapeutic effect they need to be taken up specifically by tumor cells. Researchers have now used targeted viral vectors as carriers to bring the gold nanoparticles to the location where they need to work.
Coating metallic nanoparticles in boron nitride could lead to new biomaterials for medical research and applications as well as nanoscale electromagnetic high frequency nanoscale electromagnetic devices.
Greatly expanding on previously reported work on platinum nanostructures, researchers at Sandia National Laboratories just released a new paper describing a range of novel platinum nanostructures with potential applications in fuel and solar cells as well as nanotags in biomedicine.
A new method for preparation of a double-layered nanoporous membrane suitable for virus filtration was developed.
Researchers in Switzerland for the first time managed the detection of a protein with inorganic nanopores, opening such possibilities as drug screening on a single molecule level.
