Polymers with copper show promise for implanted sensors
Developing chemical sensors that can be placed in the bloodstream or under the skin to continuously monitor oxygen, acidity (pH), or glucose levels is a major challenge for analytical chemists and biomedical engineers. The problem is, the body responds to these foreign objects in ways that interfere with their ability to accurately measure blood chemistry. In the bloodstream, clots form on the su...Cancer cells forming blood vessels send their copper to the edge
New information about a link between the growth of blood vessels critical to the spread of cancer and the copper in our bodies has been discovered by researchers from the U.S. Department of Energy's Argonne National Laboratory and the University of Chicago, using a beamline at the Advanced Photon Source. Growing new blood vessels from existing ones ?a process called angiogenesis ?is import...Copper Colorimetric Assay Kit, QuantiChrom from BioAssay Systems
Description:One-step, microplate or cuvet, colorimetric, linear detection range 8 mg/dL to 300 mg/dL. Procedure: 5 min....With copper pricing skyrocketing, fiber-optics is the way to go
Copper is dead. Evidently that mantra, though, is not shared by some analysts on Wa...Higher-Dose Copper IUDs Provide Better Pregnancy Protection
Intrauterine devices that contain higher doses of copper are more effective in preventing pregnancy than IUDs with lower copper doses, according to a new systematic review// of studies. In addition, increasing the copper content does not cause an increase in side effects prompting removal of the device, such as bleeding and pain, the review found. “In general, the comparat...High-Fat, Copper-Rich Diets Associated with Increased Rates of Cognitive Decline
Among older adults whose diets are high in saturated and trans fats, a high intake of copper may be associated with an accelerated rate of decline in thinking, learning// and memory abilities. Although copper, zinc and iron are essential for brain development and function, an imbalance of these metals may play a role in the development of brain plaques associated with Alzheimer’s dise...Copper Alloys Surfaces Touted As Pathogen Killers
Three types of alloy surfaces containing at least 90 per cent copper completely eliminate E. coli O157:H7, according to an ongoing UK study of the pathogen-killing// properties of the metal. The study gives machine makers a range of options when deciding on the mix of metals they use to coat the insides of their cooking surfaces, thus providing processors with a better means of elimin...Cancer Cells Forming Blood Vessels Send Their Copper to the Edge
Researchers have discovered new information about a link between the growth of blood vessels critical to the spread of cancer and the copper in our bodies. // Growing new blood vessels from existing ones — a process called angiogenesis — is important in growth, development and wound healing. But it also enables the spread of tumors throughout the body, so researchers have been scrambli...Solid Copper Malleable Stylette
