Nanotechnology process makes heat-resistant dyes

Optical dyes can be used to control color and light in applications ranging from laser welding to production of sunglasses and plasma TVs. The dyes used for this purpose are often expensive; others are cheap but apt to decompose when exposed to heat. A better set of options - optical dyes that are both economical and stable - is about to hit the market.

Novel porous silicon microfabrication technique increases sensing ability

Researchers have developed a novel method for improving silicon-based sensors used to detect biochemicals and other molecules in liquids. The simplified approach produces micro-scale optical detection devices that cost less to make than other designs, and provide a six-fold increase in sensitivity to target molecules.

Nanotechnology researchers use green tea benefits to fight cancer

Green tea has long been known for its anti-oxidant, anti-cancer, anti-aging and anti-microbial properties. A group of researchers has taken the health benefits of green tea to the next level by using one of its ingredients to develop a drug delivery system, which kills cancer cells more efficiently.

Scrolling nanosheets on demand

Nanoparticles have the potential to revolutionize the medical industry, but they must possess a few critical properties. First, they need to target a specific region, so that they do not scatter throughout the body. They also require some sort of sensing method, so that doctors and researchers can track the particles. Finally, they need to perform their function at the right moment, ideally in response to a stimulus. Scientists are trying to develop new particles with unprecedented properties that still meet these requirements.
