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.
