Nanotechnology helps scientists measure the forces that hold proteins together

Rice University physicists have written the next chapter in an innovative approach for studying the forces that shape proteins -- the biochemical workhorses of all living things.

Reversible cell-specific drug delivery with aptamer-functionalized liposomes

For cancer drug developers, finding an agent that kills tumor cells is only part of the equation. The drug must also spare healthy cells, and - ideally - its effects will be reversible, to cut short any potentially dangerous side effects.

Spectrum Pharmaceuticals acquires rights and IP for Renazorb

Spectrum Pharmaceuticals today announced that it has acquired 100% rights to RenaZorb (a family of compounds represented by SPI-014, also known as RZB-014), a lanthanum-based nanotechnology compound with potent and selective phosphate binding properties, for all human and non-human indications.

A new startup at California Nanosystems Institute

UCLA's newly launched on-campus technology incubator at the California NanoSystems Institute (CNSI) has opened lab space to MediSens Wireless, a startup company that develops and manufactures personal body-monitoring systems for medical and health applications.

Research looks at health and environmental effects of exposure to nanoparticles

A new study raises the possibility that flies and other insects that encounter nanomaterial "hot spots," or spills, near manufacturing facilities in the future could pick up and transport nanoparticles on their bodies, transferring the particles to other flies or habitats in the environment.

Boosting agricultural research in the developing world key to food security

Boosting agricultural research in the developing world is the key to ensuring food security for the world's poorest, says Adel el-Beltagy, Chair of the Global Form on Agricultural Research (GFAR), writing in the latest issue of the TWAS Newsletter, published last week.

Carbon nanosensor sniffs out kidney disease

A carbon nanosensor “electronic nose” - first developed by Technion-Israel Institute of Technology researchers to detect cancer from breath samples - has been modified to identify chronic renal failure (CRF).

New microchip technology may accelerate drug discovery for cancer, other diseases

Flasks, beakers and hot plates may soon be a thing of the past in chemistry labs. Instead of handling a few experiments on a bench top, scientists may simply pop a microchip into a computer and instantly run thousands of chemical reactions, with results - literally shrinking the lab down to the size of a thumbnail.

Tiny device to 'sniff out' disease, heart attacks, poison and environmental pollution

Like the sensitive seismographs that can pick up tremors of impending earthquakes long before they strike, a similar invention from Tel Aviv University researchers may change the face of molecular biology.

Lasers and nanotubes offer potential future cancer treatments

By injecting man-made, microscopic tubes into tumors and heating them with a quick, 30-second zap of a laser, scientists have discovered a way to effectively kill kidney tumors in nearly 80 percent of mice. Researchers say that the finding suggests a potential future cancer treatment for humans.

Dynamic, 3D pattern formation within protein-based gel

Modern regenerative medicine is on the lookout for implantable materials that can change as the surrounding tissue does, and two Stanford University researchers have made some new gel materials that do just that. Karin Straley and Professor Sarah Heilshorn have developed a method for preparing protein-based implant materials that can evolve with the changing needs of the host biological system. Not only can their new materials change in different ways at different times, they can do so at different places within the implant materials.

New nano-gene therapy technique could fight late-stage tumors

Tiny particles carrying a killer gene can effectively suppress ovarian tumor growth in mice, according to a team of researchers from MIT and the Lankenau Institute.

Nanoparticles show potential as part of new therapy for advanced ovarian cancer

Nanoparticle delivery of diphtheria toxin-encoding DNA selectively expressed in ovarian cancer cells reduced the burden of ovarian tumors in mice, and researchers expect this therapy could be tested in humans within 18 to 24 months, according to a report in Cancer Research, a journal of the American Association for Cancer Research.

Maternal exposure to nanoparticles related to neurological dysfunction in the mouse

Maternal exposure to nanoparticles of titanium dioxide (TiO2) affects the expression of genes related to the central nervous system in developing mice. Researchers writing in BioMed Central's open access journal Particle and Fibre Toxicology found that mice whose mothers were injected with the nanoparticles while pregnant showed alteration in gene expression related to neurological dysfunction.

Scientists combine two nanoparticles into one tiny package

Nanoparticles are being developed to perform a wide range of medical uses - imaging tumors, carrying drugs, delivering pulses of heat. Rather than settling for just one of these, researchers at the University of Washington have combined two nanoparticles in one tiny package.
