Abstract

Provided herein are optical systems and methods for detecting and characterizing particles. Systems and method are provided which increase the sensitivity of an optical particle counter and allow for detection of smaller particles while analyzing a larger fluid volume. The described systems and methods allow for sensitive and accurate detection and size characterization of nanoscale particles (e.g., less than 50 nm, optionally less than 20 nm, optionally less than 10 nm) for large volumes of analyzed fluids.
