Abstract
A process for sizing two-dimensional nanostructures includes providing the nanostructures to a liquid-liquid interface, providing probe particles to the liquid-liquid interface, obtaining an image of the nanostructures and the probe particles, and processing the image to ascertain a size property of the nanostructures.
Claims37
A system for sizing two-dimensional nanostructures, the system comprising:
- a housing including at least one biphasic fluid chamber, said chamber having an imaging surface and at least one port positioned along an imaging surface of the chamber proximate to an immiscible boundary formed by disparate fluids confined within the chamber;
- an optical imaging instrument configured to capture an image of contrasted samples contained within the chamber along substantially all of the imaging surface;
- and
- a microprocessor configured to receive and determine characteristics of the contrasted sample.
A process for determining a size property of two-dimensional nanostructures in a sample, the process comprising:
- providing a sample composition comprising two-dimensional nanostructures to a liquid-liquid interface;
- providing probe particles to the liquid-liquid interface;
- capturing an image of the two-dimensional nanostructures and the probe particles at the liquid-liquid interface;
- and
- processing the image to determine the size property.
