Tailored Noble Metal Nanoarrays via Nanoxerography

Noble metal nanoarrays have become essential in fields such as bioanalysis, catalysis, and optoelectronics. Their unique properties, often tuned through precise control of the size, morphology, and metal composition, have driven significant advancements. This research introduces atomic force microscopy (AFM)-assisted nanoxerography as a versatile technique for fabricating customizable noble metal nanoarrays. By integrating nanoxerography with in situ growth and annealing, we demonstrated precise control over spot dimensions, structural features, and metal diversity. The nanoscale precision of AFM scanning enables the creation of arbitrary patterns and the hybridization of various materials. The high tunability and efficiency of nanoxerography provide promising avenues for advancing applications of noble metal nanoarrays across diverse scientific application.
