Transparent orthodontic brackets by microinjection

...basically twofold: the use, as base material, of a polymer with high mechanical properties but of poor injectability, and the employment of microtechnologies as a means of manufacture, both for the mould itself as well as for the subsequent microinjection moulding of the plastic bracket. It is at this second...

Novel imaging technique shows lymph nodes, metastases in breast cancer without surgery

...netic signal. Some of these elaborate scaffolds of polymer each hold a remarkable 256 ions of gadolinium, a rare-earth metal and common magnetic signal in MRI. Dendrimers give a stronger signal even when adjusted for their high molecular weight, and a crisper image because their bulkiness keeps them from lea...

Researchers invent way to determine optimal conditions for spinal cord nerve regen in lab animals

...affolding consists of several innovations. It uses polymer chemistry to create a biodegradable material that can be molded, through microfabrication techniques, to make implantable, trellis-like scaffolding that both supports and guides new nerve fibers. It does this by providing channels through which the a...

Study: Carbon dioxide may find new use in producing medical implants

...fect Tomasko suspects is due to the tightly packed polymer chains that make up the plastic. "We think the CO2 lubricates the polymer chains so the protein molecules can slip in-between," he said. For the next step in this research, t...

Optical glucose sensor holds promise for diabetics and intensive care patients

...thin-film hydrogel." The hydrogel, a biocompatible polymer similar to that used to make soft contact lenses, is permeable to glucose. The sensing system has two components: a fluorescent dye and a "quencher" that is responsive to glucose. In the absence of glucose, the quencher binds to the dye and prevents ...

Researchers identify key risk factor for cataracts

...rhaps we could replace the vitreous gel with a gel polymer that would keep oxygen away from the lens by replacing the barrier between the retina and the lens," Beebe says. "Those are things we haven't thought about much because, frankly, we didn't know what the vitreous did. Now that we're beginning to get a...
