Morphological parameters of biological nanoparticles (BNPs) have strong implications on their fate and functionality in vivo e.g., circulation, biodistribution, and clearance. Although interferometric scattering microscopy modalities have demonstrated the label-free detection of sub-100 nm BNPs including viruses and exosomes; they have an insufficient spatial resolution roughly limited to the illumination wavelength. Here, we introduce computational imaging to interferometric scattering microscopy with asymmetric illumination and demonstrate a two-fold resolution enhancement. We demonstrate high-resolution imaging of nanoparticles across a large field-of-view of 100 µm × 100 µm. This novel imaging platform enables ultrasensitive and label-free morphological visualization of low-index sub-diffraction-limited BNPs in a high-throughput manner at subwavelength resolution.
