Abstract Histology involves the observation of structural features in tissues using a microscope. While diffraction-limited optical microscopes are commonly used in histological investigations, their resolving capabilities are insufficient to visuali

We present a highly spatially sensitive quantitative phase microscopy system integrated with on-chip nanoscopy to visualize 3D morphology of liver sinusoidal endothelial cells (LSECs). We used the system to obtain 3D morphology of LSEC by using chip-

On-chip super-resolution optical microscopy is an emerging field relying on waveguide excitation with visible light. Here, we investigate two commonly used high-refractive index waveguide platforms, tantalum pentoxide (Ta2O5) and silicon nitride (Si3

Total internal reflection fluorescence (TIRF) is commonly used in single molecule localization based super-resolution microscopy as it gives enhanced contrast due to optical sectioning. The conventional approach is to use high numerical aperture micr
