We　report　a　direct　optical　super-resolution　imaging　approach　with　25　nm　(similar　to　lambda/17)　lateral　resolution　under　488　nm　wavelength　illumination　by　combining　fused　silica　and　polystyrene　microspheres　with　a　conventional　scanning　laser　confocal　microscope　(SLCM).　The　microsphere　deposited　on　the　target　surface　generates　a　nanoscale　central　lobe　illuminating　a　sub-diffraction-limited　cross-section　located　on　the　target　surface.　The　SLCM　confocal　pinhole　isolates　the　reflected　light　from　the　near-field　subdiffractive　cross-section　and　suppresses　the　noises　from　the　side　lobe　and　the　far-field　paraxial　focal　point.　The　structural　detail　of　the　subdiffractive　cross-section　is　therefore　captured,　and　the　2D　target　surface　near　the　bottom　of　microspheres　can　be　imaged　by　intensity-based　point　scanning.
