Abstract :
Optical imaging of sub-micron features requires high resolution and contrast. Using no imaging lenses, we achieve a numerical aperture of 0.92 over a large field-of-view (FOV) of e.g., >20 mm2. In parallel, we significantly enhance image contrast using self-assembled nanolenses, which form catenoids at the nanoscale, enabling sub-100-nm particle and virus detection over a wide FOV.
