Wrinkled membranes create novel drug-delivery system
A University of Illinois scientist studying how membranes wrinkle has discovered a novel system for on-demand drug delivery. Sahraoui Chaieb, a professor of mechanical and industrial engineering, has created temperature-sensitive capsules that can release drugs on demand. The capsules, which can range in size from 10 to 100 microns, can be tuned to deliver drugs at different rates. Chaieb...Applied scientists create wrinkled 'skin' on polymers
Applied scientists demonstrated a new method for developing wrinkled hard skins on the surface areas of polymers using a focused ion beam. By controlling the direction and intensity of the ion beam, the researchers literally sculpted patterns on flat areas of polydimethylsiloxane, a silicon-based organic polymer (more commonly known as the primary ingredient in Silly Putty). The technique has pot...Study States Smokers With Wrinkled Faces More Easily Prone To COPD
A new study suggests that middle-aged smokers with heavily wrinkled faces have a five times higher risk of lung disease than their un-wrinkled peers//. The study explains that having wrinkles was associated with a group of conditions known as chronic obstructive pulmonary disease (COPD). A team of researchers from the Royal Devon and Exeter Hospital on 149 people conducted the study,...Research Finds, Risk Of Pulmonary Disease Increases With Wrinkled Smokers
Research published in the Journal Thorax suggests that middle aged smokers with heavily wrinkled face have 5 times more risk of getting chronic obstructive// pulmonary disease (COPD) than others. COPD is an umbrella term for a range of progressive chronic lung diseases, such as emphysema and bronchitis, which block the airways and restrict oxygen flow around the body. In exces...
