A generic in situ seed-mediated size-control method in the case of cuprous oxide nanocubes and their antibacterial activities†
Abstract
A broad size range of cuprous oxide (Cu2O) nanocubes from 36 nm to 450 nm are obtained by an in situ seed-mediated approach that simply requires two additions of deionized water. The as-prepared Cu2O nanocubes are found to have strong antibacterial activity towards both Gram-negative and Gram-positive bacteria.
