Drexel University College of Engineering researchers have successfully developed carbon nanotube-tipped pipettes that could become key to cell biology in-situ DNA sequencing and organelle-targeted drug delivery.
According to the researchers, this development makes it possible to perform injections or probe the fluid, not just inside a cell, but in specific regions inside the cell, maybe even specific organelles. The probe has the possibility of transferring fluids through the carbon nanotube (CNT) into and out of the pipette, thereby bridging the gap between existing microscale technologies and nanoscale interactions.
