Scientists develop new way to detect threatening nanoparticles in food

Over the last few years, the use of nanomaterials for water treatment, food packaging, pesticides, cosmetics and other industries has increased. For example, farmers have used silver nanoparticles as a pesticide because of their capability to suppress the growth of harmful organisms. However, a growing concern is that these particles could pose a potential health risk to humans and the environment.

Technique for developing more targeted drugs using molecular "robots"

Many drugs such as agents for cancer or autoimmune diseases have nasty side effects because while they kill disease-causing cells, they also affect healthy cells. Now a new study has demonstrated a technique for developing more targeted drugs, by using molecular "robots" to hone in on more specific populations of cells.

Nanofiber scaffolds regulate apoptosis, proliferation in neural stem cells by altering gene expression

The surface characteristics of nanoscaffolds made by nanotechnology are more similar to the three-dimensional topological structure of the extracellular matrix and the effects on the biological behaviors of cells and tissue repair are more beneficial.

Solar-powered sterilization system could be boon for people who lack adequate sanitation

Rice University nanotechnology researchers have unveiled a solar-powered sterilization system that could be a boon for more than 2.5 billion people who lack adequate sanitation. The "solar steam" sterilization system uses nanomaterials to convert as much as 80 percent of the energy in sunlight into germ-killing heat.

Nanotechnology drug kills brain-tumor cells and retards growth of tumor blood vessels

An experimental drug in early development for aggressive brain tumors can cross the blood-brain tumor barrier and kill tumor cells and block the growth of tumor blood vessels, according to a study led by researchers at the Ohio State University Comprehensive Cancer Center - Arthur G. James Cancer Hospital and Richard J. Solove Research Institute (OSUCCC - James).

Gold nanofibers in engineered heart tissue can enhance electrical signalling, find researchers

Heart tissue sustains irreparable damage in the wake of a heart attack. Because cells in the heart cannot multiply and the cardiac muscle contains few stem cells, the tissue is unable to repair itself - it becomes fibrotic and cannot contract properly.

NIDA grants $3.3M to design vaccine conferring immunity to nicotine

A chemical component present in the nightshade family of plants is one of the world's most tenaciously addictive substances. It is the nicotine contained in tobacco and found in high concentrations in cigarettes. Smoking remains a global scourge; in the U.S. it is the leading source of preventable death.

Nano and laser technology packed into small device tests antibiotic treatment in minutes

Researchers at EPFL have built a matchbox-sized device that can test for the presence of bacteria in a couple of minutes, instead of up to several weeks. A nano-lever vibrates in the presence of bacterial activity, while a laser reads the vibration and translates it into an electrical signal that can be easily read-the absence of a signal signifies the absence of bacteria.

Biomolecular interactions of nanoparticles can improve drug development, optical sensors and more

In chemical reactions, left and right can make a big difference. A "left-handed" molecule of a particular chemical composition could be an effective drug, while its mirror-image "right-handed" counterpart could be completely inactive.

Ingestion of nanoparticles at typical environmental levels unlikely to cause overt toxicity

Ingestion of commonly encountered nanoparticles at typical environmental levels is unlikely to cause overt toxicity, according to US researchers. Nevertheless there is insufficient evidence to determine whether chronic exposures could lead to subtle alterations in intestinal immune function, protein profiles, or microbial balance.
