Fabrication of nanomotors and applications thereof for surface writing

Abstract

A method for surface writing is disclosed. The method includes fabricating a plurality of nanomotors, forming a secondary solution by adding the plurality of nanomotors to a primary solution placed on a substrate, guiding the plurality of nanomotors along a path in the secondary solution, and forming a sol-gel film along the path on a surface of the substrate. Wherein, the primary solution includes a monomer and hydrogen peroxide (H2O2). Fabricating the plurality of nanomotors includes preparing a mesoporous silica template, forming the plurality of nanomotors within the mesoporous silica template, and separating the plurality of nanomotors from the mesoporous silica template. The mesoporous silica template includes a plurality of channels, wherein each channel of the plurality of channels has a diameter less than about 50 nm and a length of less than about 100 nm, and each nanomotor of the plurality of nanomotors is formed within a channel of the plurality of channels.
