Wearable textile bandage releases wound-healing drugs on demand

Multiple approaches have been described for achieving therapeutically-effective wound healing. Biological factors that induce stimulation of cells to trigger and enhance the healing process have been extensively studied, and recently, new approaches for their delivery have been the focus of a vast number of studies. Delivery issues inherent to wound dressings include the need to

Dual component nanofiber/hydrogel scaffold supports therapeutic drug and gene delivery

One of the structurally more attractive features of nanofiber scaffolds is their three-dimensional architecture. Because they are thought to more closely mimic the size and environment of the natural extracellular matrix in the body, they continue to be studied not only as cell support scaffolds, but, a new study has shown, robust drug and gene delivery vehicles. Moreover,
