Latest Patents

One of his latest patents is titled "Method for preparing hollow latexes." This invention outlines a process for creating hollow polymer latexes through a one-stage emulsion polymerization. The method involves introducing an effective amount of a first charge of an organic phase to an aqueous phase, where the organic phase contains monomers that are virtually insoluble in the aqueous phase. The polymerization process results in a low molecular weight polymer that phase separates from the organic phase, forming a hollow polymer latex particle.

Another significant patent is "Latex-antigen-antibody complexes for immunoassay." This invention describes a latex particle made from a vinyl aromatic monomer and a vinyl acrylate ester monomer, modified to facilitate protein binding. The resulting latex particles are useful in diagnostic test applications, providing utility in complex protein systems to form latex antigen/antibody complexes.
