Abstract:
The development of cantilever-free scanning probe techniques has allowed inexpensive, reproducible, and high-throughput patterning of both hard and soft nanomaterials over large areas. Specificallyscanning probe block copolymer lithography (SPBCL) allows one to generate nanoreactors consisting of polymers loaded with metal precursors, which upon thermal treatment can be converted into well-defined nanoparticles. Since one can finely tune both the size and composition of the polymer nanoreactors, nanoparticles of complex compositions can be synthesized with control over size from the 1 to 50 nm length scale. Furthermore, by using 1 million pyramidal pens in a single array, one can probe a wide variety of nanoparticles that systematically vary in size and composition. Nanoparticle libraries made in this manner can be metals, metal oxides, multimetallic alloys, and janus structures. This novel approach lays the foundation for creating new libraries of materials, where scale, in addition to composition becomes an important library parameter.
