To study certain aspects of cells, researchers need the ability to take the innards out, manipulate them, and put them back. Options for this kind of work are limited, but researchers describe a 'nanoblade' that can slice through a cell's membrane to insert mitochondria. The researchers have previously used this technology to transfer other materials between cells and hope to commercialize the nanoblade for wider use in bioengineering.
