Movable thin films with embedded high-index microspheres for super-resolution microscopy

TL;DR

This paper introduces a movable PDMS thin film with embedded high-index microspheres, enabling sample scanning for super-resolution microscopy and overcoming the limited field-of-view of traditional microsphere-assisted imaging.

Contribution

The authors develop a movable thin film platform with embedded microspheres, allowing for larger field-of-view in super-resolution microscopy.

Findings

Enhanced field-of-view in microsphere-assisted imaging

Sample scanning capability demonstrated

Potential for broader application in super-resolution microscopy

Abstract

Microsphere-assisted imaging emerged as a surprisingly simple way of achieving optical super-resolution imaging. In this work, we use movable PDMS thin films with embedded high-index barium titanate glass microspheres a sample scanning capability was developed, thus removing the main limitation of this technology based on its small field-of-view.
