Chemical engineers at the Massachusetts Institute of Technology have designed a new type of drug-delivery nanoparticle that exploits a trait shared by almost all tumors: They are more acidic than healthy tissues. Such particles could target nearly any type of tumor, and can be designed to carry virtually any type of drug.

A class of engineered nanoparticles - gold-centered spheres smaller than viruses - has been shown safe when administered by two alternative routes in a mouse study led by investigators at the Stanford University Medical School. This marks the first step up the ladder of toxicology studies that, within a year and a half, could yield to human trials of the tiny agents for detection of colorectal and possibly other cancers.

Nanotechnology researchers have known for years that RNA, the cousin of DNA, is a promising tool for nanotherapy, but the difficulties of producing long-lasting, therapeutic RNA that remains stable and non-toxic while entering targeted cells have posed challenges for their progress. Now, in two papers published in the journal Molecular Therapy, a team of investigators details their method for producing RNA nanoparticles and testing their safety in the delivery of therapeutics to targeted cells.

Melding nanotechnology and medical research, researchers from Sandia National Laboratories, the University of New Mexico, and the UNM Cancer Research and Treatment Center have produced an effective strategy that uses nanoparticles to treat tumors with a melange of anticancer agents. This strategy relies on using silica nanoparticles honeycombed with cavities that can store large amounts and varieties of drugs loaded inside a lipid-based nanoparticle known as a liposome.

A team of investigators from Stanford University has developed a new biosensor microchip that could significantly speed up the process of drug development. The microchips, packed with highly sensitive magnetic nanosensors, analyze how proteins bind to one another, a critical step for evaluating the effectiveness and possible side effects of a potential medication.

In the computer displays of medical equipment in hospitals and clinics, liquid crystal technologies have already found a major role. But a discovery reported from the University of Wisconsin-Madison suggests that micrometer-sized droplets of liquid crystal, which have been found to change their ordering and optical appearance in response to the presence of very low concentrations of a particular bacterial lipid, might find new uses in a range of biological contexts.

Scientists at the California Institute of Technology (Caltech) have conducted experiments confirming which of three possible mechanisms is responsible for the spontaneous formation of three-dimensional pillar arrays in nanofilms. These protrusions appear suddenly when the surface of a molten nanofilm is exposed to an extreme temperature gradient and self-organize into hexagonal, lamellar, square, or spiral patterns.
