Abstract Numerous structures at the nano and microscale manifest distinctive properties with far-reaching implications across diverse fields, including electronics, electricity, medicine, surface engineering. Established methods such as nanoimprint lithography, photolithography, self-assembly play crucial roles in fabrication of nano- microstructures; however, they exhibit limitations generating high-aspect-ratio when utilizing high-viscosity photocurable resins. In response to this inherent challenge, we propose a highly cost-effective approach facilitating direct replication structures, specifically nanowires, through utilization anodized aluminum substrates. This study elucidates streamlined process for multiscale porous surfaces achieved evaporation-induced integration solid nanowires printed resin.
