Nanoparticles as potential biomarker harvesters

Nanoparticles can be modified to create selective surfaces for targeted molecular interactions. As the biomarker populations present in blood are more fully characterized, nanoparticle harvesting platforms will have significant potential improve the detection of diseases at an early, more treatable stage.

Using nanofibers to repair the heart

The human heart does not have significant regeneration capabilities and cardiologists look to cell therapy as a promising new method for cardiac repair. Now there is a new delivery system that improves the results of cell therapy. The new system allows greater control of the intramyocardial environment (inside the heart muscle) by delivering growth factors to an injured heart muscle and using peptide nanofibers for prolonged delivery of the injected factor.

Smart magnetic hydrogels for drug release

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.

Controlled drug delivery systems in neurodegenerative diseases

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.

Combining gold nanoparticles with viruses for a combined thermal/gene cancer therapy

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.

Novel platinum nanostructures

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.
