Scientists have developed a new technique which would help for the study of various intracellular processes and also help in gene delivery. This technique will help to examine the processes that go on inside a single human cell. Carbon nanotubes (CNTs) nanoinjector is the first to penetrate a cell with no membrane damage, even after hour-long, repeated use. This is the first cell injector with temporal and spatial control on the nanometer scale that can deliver a discrete number of molecules and doesn't damage the cell membrane. This nanoinjecter will help in experimental cell biology with its ability to overcome the plasma membrane barrier. The nanoinjector also offers the opportunity for injecting cargo such as DNA, RNA, polymers, bacteria and other particles.

CNT nanoinjector is simply its small size, a CNT needle pierces a hole so small that it is quickly healed by lipid diffusion.
