Abstract
A nanoporous metal can be formed by projecting laser patterns using a spatial light modulator (SLM) onto a gold/silver alloy film immersed in diluted nitric acid solutions. Heat accumulation induced by the photothermal effect enables localized dealloying in dilute nitric acid. NPG micropatterns can be formed at the irradiated spots while the surrounding alloy remains intact.
