A nanoparticle drug delivery system designed for brain tumor therapy has shown promising tumor cell selectivity in a novel cell culture model devised by University of Nottingham scientists.
The nanoparticles used in this study were prepared from a novel biodegradable polymer poly(glycerol adipate). The polymer has been further modified to enhance incorporation of drugs and make the nanoparticles more effective.
We are approaching an evolutionary event horizon, where the organic and the synthetic, the virtual and the “real”, are merging together into an operational ecology, an existence morphology for which there is no precendent in the history of which we are currently aware, catalyzed by nanotechnology
Researchers from the University of Delaware and Washington University in St. Louis have figured out how to train synthetic polymer molecules to behave–to literally “self-assemble” –and form into long, multicompartment cylinders 1,000 times thinner than a human hair, with potential uses in radiology, signal communication and the delivery of therapeutic drugs in the human body. The discovery, a fundamental new tool for nanotechnology, is reported in the Aug. 3 issue of the prestigious journal ‘Science.’
When it comes to searching out cancer cells, gold may turn out to be a precious metal.
Purdue University researchers have created gold nanoparticles that are capable of identifying marker proteins on breast cancer cells, making the tiny particles a potential tool to better diagnose and treat cancer. The technology would be about three times cheaper than the most common current method and has the potential to provide many times the quantity and quality of data, said Joseph Irudayaraj, an associate professor of agricultural and biological engineering.
The ability to pump liquids at the cellular scale opens up exciting possibilities, such as precisely targeting medicines and regulating flow into and out of cells. But designing this molecular machinery has proven difficult.
Now chemists at the University of Illinois at Chicago have created a theoretical blueprint for assembling a nanoscale propeller with molecule-sized blades.
