Hexagonal polypyrrole nanosheets from interface driven heterogeneous hybridization and self-assembly for photothermal cancer treatment

Abstract

Hexagonal polypyrrole (PPy) nanosheets with highly ordered lateral orientation were developed by the generation and directed self-assembly of dopamine induced FeOOH–PPy heterostructures on nanoscale THF/water interfaces. The size-controlled nanosheets possess attractive photothermal conversion properties, which facilitate efficient photothermal inhibition of cancer cells.
