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.

Contouring measurement methods are important for high quality, high speed and productivity machining in order to achieve the high precision required. Among the most commonly used methods, no measuring techniques have been available with nanometer resolution except for the grating encoder measurement system.

Researchers at Cornell University have developed a novel quantitative nanoparticle-based sensor of chemical concentrations based on organic dye molecules covalently integrated into the matrix of silica nanoparticles. This is the first work that implements an optimized core-shell architecture for such sensor particles.

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.
