Injections are a useful tool for cell biologists. They allow researchers to administer proteins and chemicals directly to the inside of a single cell. A new technique, developed at Rockefeller University, makes this possible for the first time in cells that were previously considered too hard to be penetrated by traditional methods. By using a micropipette like a saw and combining it with a small electric motor, scientists have now successfully administered fluorescent proteins to yeast cells.
