The controlled preparation and collection of the micelle-scale single hollow particle from colloidal solutions remain a great challenge due to their small size and low density that is beyond the separation capability of centrifugation and filtration. Herein, an effective strategy for the preparation and separation of micelle-scale single hollow polymer sphere (SHPS) from a stable colloid system was presented, and inspired by “net-fishing”, 2D graphene oxide (GO) nanosheets were utilized as the fishing nets to capture such SHPSs from the colloidal solution via electrostatic attraction. As a consequence, SHPSs were enriched on the GO surface. In a control case, they would automatically assemble into monolayer ordered hexagonal honeycomb-like nanoarrays on the entire surface of GO. Moreover, the key factors of the formation of the ordered nanoarrays and the arrangement rules were studied by adjusting parameters such as pH and the mass ratio of SHPS/GO, and the formation mechanism of the ordered nanoarray was also demonstrated with the model study. This strategy provides a new avenue to capture lightweight colloidal particles and thus construct multiple ordered assemblies.
