Coating the Outer Surface of Glass Nanopipette with Chlorobenzene-Terminated Polysiloxane

Abstract

A method of outer surface modification of glass nanopipette with chlorobenzene- terminated organopolysiloxane has been developed. Scanning electron microscope images and microscopic Raman spectra revealed the efficacy of the coating. Energy dispersive X-ray spectra showed not only the materials adsorbed on the nanopipette but also the change in stoichiometry of the bulk glass resulting from the fabrication process of the nanopipette with a laser puller. The coating method is easy to treat and can be used for various applications such as the prevention of carbon contamination from the materials during the injection to biomaterials such as living cells.
