Jagged Graphene Edges Can Slice Into Cell Membranes
July 10, 2013
Researchers at Brown University have shown how tiny graphene sheets can be big trouble for cells. Sharp corners and jagged edges on the sheets puncture cell membranes, allowing the sheet to enter the cell and disrupt function. The new understanding of how graphene interacts with cells could lead to safer production of this important nanomaterial.
The National Science Foundation (NSF) is an independent federal agency that supports fundamental research and education across all fields of science and engineering. In fiscal year (FY) 2015, its budget is $7.3 billion. NSF funds reach all 50 states through grants to nearly 2,000 colleges, universities and other institutions. Each year, NSF receives about 48,000 competitive proposals for funding, and makes about 11,000 new funding awards. NSF also awards about $626 million in professional and service contracts yearly.
