Popis: We fabricated thin-films made from polydimethylsiloxane (PDMS) with embedded high-index (n~1.9-2.2) microspheres for super-resolution imaging applications. To control the position of microspheres, such films can be translated along the surface of the nanoplasmonic structure to be imaged. Microsphere-assisted imaging, through these matrices, provided lateral resolution of ~{\lambda}/7 in nanoplasmonic dimer arrays with an illuminating wavelength {\lambda}=405 nm. Such thin films can be used as contact optical components to boost the resolution capability of conventional microscopes.
