pipettes
A pipette (sometimes spelled as pipett) is a laboratory tool commonly used in chemistry, biology and medicine to transport a measured volume of liquid, often as a media dispenser. Pipettes come in several designs for various purposes with diffe ...

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. After glass nanopipettes are fabricated and coated with carbon layer in different ways, wet-etching method is applied to get carbon nanopipettes.
[M. Schrlau, E. Falls, B. Ziober and H. Bau, Nanotechnology, 2008, 19, 0151101] Wet-etching method is done to get rid of glass nanopipettes.

Nanopipettes allowed to explore protusions, dendrites and more general the properties of nanostructures, known as nanophysiology.]
