PHILADELPHIA, Jan. 16 (UPI) -- U.S. scientists have created carbon nanopipettes thousands of times thinner than human hair that can measure electric current and deliver fluids into cells.
University of Pennsylvania researchers said the tiny carbon-based tool can be used to probe cells with minimal intrusion and inject fluids without damaging or inhibiting cell growth. The nanopipettes might replace glass micropipettes that are fragile at small scales, can cause irreparable cell damage and cannot be simultaneously used as injectors and electrodes, the scientists said.
The carbon-based pipettes -- developed by Professor Haim Bau and colleagues -- range in size from a few tens to a few hundred nanometers and are said to be far stronger and more flexible than traditional glass micropipettes.
