Dean's Distinguished Lecture: Chad Mirkin
Multicomponent nanoparticles have many novel chemical and physical properties that are greater than the sum of their parts, which makes them promising for a range of fields including catalysis, magnetics, plasmonics and electronics. Combinatorial screening is a common strategy to establish composition-structure-function relationships. To achieve this goal, scanning probe block copolymer lithography (SPBCL) was developed, a technique that allows one to print attoliter-size nanoreactors on substrates.
When combined with polymer pen lithography (PPL), a high-throughput cantilever-free patterning technique that utilizes an elastomeric pen array with millions of pens, combinatorial libraries of nanoparticles can be made by varying the ink composition across a 1-million-pen array. The synergy between SPBCL and PPL allows an innovative and robust solution to synthesize new nanoparticles over large areas, which enables the rapid screening of the properties of multicomponent nanoparticles. This approach lays the foundation for generating new combinatorial libraries of materials, where scale, in addition to composition, becomes an important library parameter.
