Enzymatic nanolithography of polyaniline nanopatterns by using peroxidase-modified atomic force microscopy tips.
A new enzyme nanolithography strategy for creating conducting polymer nanostructures through the modification of AFM tips with peroxidase is described. Scanning of the modified tip in the presence of aniline and hydrogen peroxide is used for biocatalytic patterning of different polyaniline nanostructures (see figure).
