A team of researchers from the University of British Columbia have created a magnetic drug implant that could offer an alternative for patients having to take several pills or intravenous injections. This implant is the first of its kind in Canada.
Researchers used small snippets of DNA as “barcodes” to develop a new technique for rapidly screening the capability of nanoparticles to selectively deliver therapeutic genes to particular organs of the body. This new technique succeeded in accelerating the development and use of gene therapies for Parkinson’s disease, cancer and heart disease.
A new technology platform, the Nano MRI Lamp, is capable of tuning the magnetic resonance imaging (MRI) signals "ON" only in the vicinity of the targeted disease. This platform was developed by a research team led by Cheon Jinwoo at the Center for Nanomedicine, within the Institute for Basic Science (IBS).
Tiny, virus-sized elements or nanoparticles created in laboratory conditions are gaining in popularity in the field of biomedicine. This quickly-evolving technology provides hope for several medical applications, both for therapies and diagnosis.
Shiny and smooth - this is how hair is visualized in advertisements for various shampoos. However, in reality, the surface of hair looks far more uneven when viewed by physicists under microscopes. The hair surface looks much more rugged, as it is formed of ratchet-like, saw-tooth scales.
Scientists at EPFL’s Laboratory of Photonic Materials and Fiber Devices, which is operated by Fabien Sorin, have developed a new technique for imprinting nanometric patterns on the outside and inside of polymer fibers. These polymer fibers may be useful in a number of applications, for instance, to produce optical effect, guide nerve regeneration, and ultimately create smart bandages and artificial tissues.
A research team working at the Department of Energy’s Lawrence Berkeley National Laboratory (Berkeley Lab) and the Hebrew University of Jerusalem in Israel confirmed with a unique infrared probe that jagged surfaces and defects found at the edges of nanosized platinum and gold particles are significant hot spots for chemical reactivity.
Topically administered drug formulations (e.g. eye drops) are used to treat most ophthalmic diseases.
Efforts to defeat cancers are often hindered by the mechanical resistance of tumors and collateral damage of standard treatments. However, a group of researchers from the CNRS, the French National Institute of Health and Medical Research (INSERM), Paris Descartes University, and Paris Diderot University have successfully softened malignant tumors by heating them.
Worms that are a millimeter-long and capable of digesting a nanoparticle-laced meal of their favorite bacteria could help to develop a way to see the working of cellular forces within human bodies and also in processes like cancer growth and wound healing.
