Bioengineers at the University of Pennsylvania have created a system to control the flexibility of the substrate surfaces on which cells are grown without changing the surface properties, providing a technique for more controlled lab experiments on cellular mechanobiology, an important step in the scientific effort to understand how cells sense and respond to mechanical forces in their environment. Researchers created a library of micromolded, hexagonally spaced elastomeric micropost arrays,...

PHILADELPHIA -- Veterinary ophthalmology researchers from the University of Pennsylvania have used gene therapy to restore retinal cone function and day vision in two canine models of congenital achromatopsia, also called rod monochromacy or total color blindness. Achromatopsia is a rare autosomal recessive disorder with an estimated prevalence in human beings of about 1 in 30,000 to 50,000. It primarily affects the function of the cone photoreceptors in the retina and serves as a...

Researchers at the University of Pennsylvania, the University of Wisconsin-Madison and IBM Research-Zrich have fabricated an ultra sharp, diamond-like carbon tip possessing such high strength that it is 3,000 times more wear-resistant at the nanoscale than silicon. The end result is a diamond-like carbon material mass-produced at the nanoscale that doesn't wear. The new nano-sized tip, researchers say, wears away at the rate of one atom per micrometer of sliding on a substrate of silicon...

U.S. scientists have formed interconnected carbon nanostructures on graphene substrates in a study that might lead to new carbon-based devices. The researchers from the University of Pennsylvania, Sandia National Laboratories and Rice University said the simple assembly process involves heating few-layer graphene sheets to sublimation using electric current. Curvy nanostructures such as carbon nanotubes and fullerenes have extraordinary properties, the scientists said, but are extremely...
