ALEXANDRIA, Va., Dec. 2 -- United States Patent no. 12,486,245, issued on Dec. 2, was assigned to THE TRUSTEES OF PRINCETON UNIVERSITY (Princeton, N.J.).

"Sequential multi-step flash nanoprecipitation for the formation of nanoparticles with high core loadings" was invented by Leon Wang (Princeton, N.J.), Kurt Ristroph (Princeton, N.J.) and Robert Prud'homme (Lawrenceville, N.J.).

According to the abstract* released by the U.S. Patent & Trademark Office: "From diagnostic imaging to drug delivery, nanoparticles have found a tremendous variety of uses across fields. Often, when designing these nanoscale constructs, the two most important criteria are particle size and core loading. For example, small particles below 100 nm can have many adva...
