Description and Applications

The Exoid Tunable Resistive Pulse Sensing (TRPS) instrument from Izon Science performs measurements on nanoparticle size, number concentration, and surface charges. As a complementary technique to other particle sizing techniques available at ANTEC (DLS and NTA), TRPS measures particle clearance events through a single nanopore by recording the temporal changes in electrical current. This technique is particularly suited for pre-purified extracellular vesicles and synthetic nanoparticles with size ranging from 40 nm to 11 µm. Nanopore modules are available for purchase at a pass-through cost.

This instrument was kindly donated by the Department of Biomedical Engineering at the McCormick School of Engineering.
