    Molecular "Fishing"

    Technologies that permit fast chemical measurement have myriad applications in medicine, the environment and food safety monitoring. However, methods that rely on heat or changes in optical properties often require long sampling times and equipment not suitable for use in the field. Additionally, optical methods can only be used when the testing solution is clear, precluding their use on blood and any other opaque solution. Did you know? To detect the interactions between individual molecules, atomic ...

    Warm Targets

    Anti-cancer drugs are hazardous to cancers, but they are only slightly less so to healthy tissue. For example, the drug doxorubicin may efficiently jam the genetic machinery of rapidly dividing cancer cells, but it is also highly toxic to heart tissue. Such cardiac toxicity limits how much of the drug can be administered to patients. Benefit "The unprecedented rapid release of such large amounts of drug directly into the cancers' blood vessels--triggered only by mild focused heating--seems ...

    Drugs that Deliver

    Chemotherapy often falls short of achieving its full impact because the drugs diffuse in and out of tumors too rapidly. That's because the small size of current chemotherapy drugs which typically have a molecular weight in the 300 to 600 range allow them to be readily excreted through the kidneys before their anti-cancer effects are fully achieved. Did you know? If you balance the ability of drug to penetrate tumors with its staying ...

    Molecular 'Fishing' Technique Paves Way for Advanced Hand-Held Sensing Devices

    A new molecular "fishing" technique developed by researchers at Duke University and Duke's Pratt School of Engineering lays the groundwork for future advances in hand-held sensing devices. Hand-held devices used for medical testing or environmental and food-safety monitoring could quickly and precisely measure concentrations of virtually any chemical substance, including blood proteins, toxic pollutants and dangerous biological agents, in a test solution, according to the researchers. The researchers describe the chemical methodology that would enable such devices ...

    Lubricant's Role in Keeping Joints Limber Comes into Sharper Focus

    Using a method that allows precise measurement of the biomechanical properties of the hip joints in mice, researchers at Duke University's Pratt School of Engineering have found new evidence that an ingredient of joint fluid called lubricin plays a significant role in keeping joints limber. The researchers say the finding offers the strongest evidence yet that treatments designed to increase levels of lubricin in humans may help stall the deterioration of arthritic joints. The team found that ...

    Harnessing Fat to Attack Cancer

    Scientists at Duke University Medical Center and Duke's Pratt School of Engineering have harnessed the much maligned fat particle to serve a higher purpose: battling human cancers. The researchers have engineered microscopic fat bubbles into "smart bombs" by packing them with anticancer drugs and dispatching them on a mission to seek and destroy cancerous tumors. Heating the tumor from the outside with microwave energy attracts the anticancer bombs to the tumor, the scientists said. Within 20 seconds ...

    'Metal Sandwich' May Break Superconductor Record

    Aleksey Kolmogorov and Stefano Curtarolo After an exhaustive data search for new compounds, researchers at Duke University's Pratt School of Engineering have discovered a theoretical "metal sandwich" that is expected to be a good superconductor. Superconductive materials have no resistance to the flow of electric current. The new lithium monoboride (LiB) compound is a "binary alloy" consisting of two layers of boron -- the "bread" of the atomic sandwich -- with lithium metal "filling" in between, the ...

    Switch in Research Focus Inspires Mechanical Engineer Kurt Wulff
