Assembly of gold nanoparticles (AuNPs) using laser-induced preparation of nanostructures has emerged as a promising approach for creating highly ordered and functional nanomaterials. AuNPs are particularly attractive due to their unique optical. In this study, the optical properties of the assembled structures were analyzed using finite element simulations, revealing tunable near-field optical responses. And we demonstrate the use of maskless femtosecond laser two-photon polymerization (2PP) to fabricate polymer templates with tetragonal and hexagonal patterns that can be used to orient and assemble AuNPs into structures with tunable optical properties. This approach creates new avenues for the design of functional nanomaterials with applications in photonics, plasmonics and biosensing.
