Abstract Fungal contaminations pose a persistent challenge in the fields of healthcare, agriculture, and industry, primarily due to their environmental adaptability increasing resistance antifungal agents. In this study Aspergillus niger is utilized as model organism. This work evaluates copper, brass, steel surfaces functionalized with ultrashort pulsed laser‐induced periodic surface structures (USP‐DLIP) designed 3 9 µm topographies. spore viability assays show that periodicities on copper achieve 99% reduction viability, indicating increased ion release key factor enhanced effectivity. Scanning electron microscopy (SEM) analysis confirm substantial damage, linked testing measured by inductively coupled plasma triple quadrupole mass spectrometry (ICP‐QQQ) spectrometry. Interestingly, structured reveal trend toward activity despite inert nature. Whereas brass do not significant improvement activity. These findings suggest USP‐DLIP structuring stainless‐steel have considerable potential for applications, although interactions between structures, released ions, fungal spores are highly complex. Yet, offers promising advantages developing advanced materials.
