High-index microspheres embedded within movable slabs, or microfibers, are used in a novel approach for super-resolution imaging of nanoplasmonic arrays.

From the article:

In summary, we have developed a rigorous analysis of resolution provided by microspheres and microfibers. We have synthesized transparent PDMS slabs that contain hundreds of embedded high-refractive-index barium titanate microspheres. Such slabs, or coverslips, can be considered as a novel optical component for super-resolution microscopy that are usable in two different ways. First, without lubrication, they adhere to various surfaces and provide λ/7 resolution. Second, with liquid lubrication, the slabs become non-sticky and can be translated along a surface so that different spheres align with various objects. In future work we will explore the resolution limits of this technology in resonant nanoplasmonic and living subcellular structures. Various technologies and materials will be used for encapsulating high-index microspheres and microfibers. We will also develop commercial applications of these super-resolution technologies through our spin-off company SupriView.
