Parameterless detection of liquid–liquid interfaces with sub-micron resolution in single-molecule localization microscopy

Measuring the Shape, Stiffness, and Interface Tension of Droplets with the Scanning Ion Conductance Microscope

“…Optical microscopy such as confocal microscopy or Brewster angle microscopy has been used to image liquid–liquid interfaces, but the resolution is inherently limited by the optical wavelength. Recent super-resolution techniques such as iPAINT are comparably slow and require fluorescent labeling of the interface, potentially modifying the physicochemical properties of the interfaces . Other techniques like X-ray or neutron scattering average over the microscopic surface area and do not provide microscale images.…”
