Controlled growth of ultranarrow nanowires on functionalized 2D materials

Abstract

A method for preparing a nanowire or nanorod on a patterned monolayer or thin film supported by a 2D material substrate in a nonpolar environment comprises the steps of: functionalizing a supporting 2D material substrate using a patterned monolayer or thin film of a polymerized amphiphiles comprising both hydrophobic and hydrophilic constituents; and then growing a nanowire or nanorod on the functionalized supporting 2D material substrate in a salt solution or suspension, wherein the patterned monolayer or thin film comprises a polymerizable phospholipid with a terminal amine. A gold nanowire or nanorod so prepared has a highly controlled diameter of about 2 nm, and a length of about 100 nm, dependent in part on molecular domain sizes in the monolayer.
