Woven Scaffolds to Improve Cartilage Repair
Using a unique weaving machine of their design, researchers led by Farshid Guilak of Duke University Medical Center and the Pratt School of Engineering have created a three-dimensional fabric "scaffold" that could greatly improve the ability of physicians to repair damaged joints with the patient's own stem cells.
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, mechanical engineering professor Stefan Zauscher's group has found new evidence that an ingredient of joint fluid called lubricin plays a significant role in keeping joints limber.
Molecular 'Fishing' Technique Paves Way for Advanced Hand-Held Sensing Devices
A new molecular "fishing" technique developed by a team of researchers at Pratt's Center for Biologically Inspired Materials and Material Systems 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.
Biomedical Engineers Advance on 'Smart Bladder Pacemaker'
Pratt researcher Warren Grill and his colleagues have moved a step closer to a "smart bladder pacemaker" that might one day restore bladder control in patients with spinal cord injury or neurological disease. The team's latest findings show that a device that taps into the urinary "circuit" in the spinal cord could selectively coordinate the contraction and release of muscles required for maintaining continence.
