Nanopipette

Nanopipettes are pipettes in nanometer scale, generally made from quartz capillaries with the help of laser-based pipette puller system.[1] Glass and carbon nanopipettes are most encountered ones in literature. Carbon nanopipettes are nanopipette shaped, hollow carbon layer. The thickness or diameter of nanopipettes can be altered. Glass nanopipettes have a wide range of usage areas like electrophysiological settings, microinjection needles etc.[2] After glass nanopipettes are fabricated and coated with carbon layer in different ways, wet-etching method is applied to get carbon nanopipettes.[3][4] Wet-etching method is done to get rid of glass nanopipettes.[3]
