We report a robust method to fabricate hierarchical photonic crystal microspheres (HPCs) with tailored multi-scale structures, versatile surface topologies, and tunable optical properties. These produced HPCs consist of well distributed gold nanoparticles (AuNPs) (as 3rd-tier) anchored on close-packed silica (SiO2NPs) nanopatterns (as 2nd-tier), which are assembled by SiO2NPs confined into micrometer spherical templates (1st-tier). These HPCs possess both photonic stop band (PSB) and surface plasmon resonance (SPR) properties. Thus, these microspheres can be applied in biochemical sensors, superwetting and surface enhanced Raman spectroscopy (SERS).
