Mechanical Regulation Effects Stem Cell Development, Adhesion

PHILADELPHIA –- 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 sc

Collaboration Leads to Simpler Method for Building Varieties of Nanocrystal Superlattices

Collaboration Leads to Simpler Method for Building Varieties of Nanocrystal Superlattices

PHILADELPHIA –- Collaboration by chemists, physicists and materials scientists at the University of Pennsylvania has created a simple and inexpensive method to rapidly grow centimeter-scale membranes of binary nanocrystal superlattices, or BNSLs, by crystallizing a mixture of nanocrystals on a liquid surface.

Cellular Workouts Strengthen Endothelial Cells' Grasp

Cellular Workouts Strengthen Endothelial Cells' Grasp

PHILADELPHIA –- University of Pennsylvania bioengineers have demonstrated that the cells that line blood vessels respond to mechanical forces — the microscopic tugging and pulling on cellular structures — by reinforcing and growing their connections, thus creating stronger adhesive interactions between neighboring cells.

New Tissue-Hugging Implant Maps Heart Electrical Activity in Unprecedented Detail

New Tissue-Hugging Implant Maps Heart Electrical Activity in Unprecedented Detail

PHILADELPHIA – A team of cardiologists, materials scientists, and bioengineers have created and tested a new type of implantable device for measuring the heart’s electrical output that they say is a vast improvement over current devices. The new device represents the first use of flexible silicon technology for a medical application.
