The hydrophobic property (film-forming ability) of PS spheres was improved by a thermo-rheology treatment before LB assembly, and a large film was obtained. In contrast to the traditional LB technique, no surfactant was needed in this method, which could eliminate the additional contamination of surfactants in the preparation process and provided the products with versa- tile applications in nanosphere lithography (NSL) for biosensor, surface plasmon resonance, and surface enhanced Raman spectroscopy .展开更多
