Catalog No. : PBL-9045
Product Name : Pyrene-PEG-FITC, MW 10k
Description :

Pyrene-PEG-FITC is one of the many PEGylated pyrene derivatives for the surface functionalization of carbon nanotubes and graphenes via the strong (close to irreversible) pi-pi stacking between the pyrene and the aromatic rings on single wall and multi-walled carbon nanotubes. Pyrene is conjugated to PEG through a very stable amide bond. It is a very simple process that requires just well dispersing CNTs with the PEG-pyrene reagents in either organic solvents or aqueous solutions. The same PEGylated pyrene reagent also works for graphene or any carbon nanoparticle surfaces with curvatures that fit well with the pyrene structure.
