biostudies-literatureUnknown10(67)Alvarez-Fernandez AIn the field of functional nanomaterials, core-satellite nanoclusters have recently elicited great interest due to their unique optoelectronic properties. However, core-satellite synthetic routes to date are hampered by delicate and multistep reaction conditions and no practical method has been reported for the ordering of these structures onto a surface monolayer. Herein we show a reproducible and simplified thin film process to fabricate bimetallic raspberry nanoclusters using block copolymer (BCP) lithography. The fabricated inorganic raspberry nanoclusters consisted of a ∼36 nm alumina core decorated with ∼15 nm Au satellites after infusing multilayer BCP nanopatterns. A series of cylindrical BCPs with different molecular weights allowed us to dial in specific nanodot periodicities (frRSC advances41088-41097https://www.ebi.ac.uk/biostudies/studies/S-EPMC9057902biostudies-literatureLarge area Al₂O₃-Au raspberry-like nanoclusters from iterative block-copolymer self-assembly.PMC9057902Hadziioannou GAlvarez-Fernandez ABarois PFleury GFontaine PPonsinet VCummins CNallet FfalseLarge area Al₂O₃-Au raspberry-like nanoclusters from iterative block-copolymer self-assembly.In the field of functional nanomaterials, core-satellite nanoclusters have recently elicited great interest due to their unique optoelectronic properties.
