Title: Liguo Song: Innovator in Polymer Solutions
Introduction
Liguo Song is a notable inventor based in Williamsville, NY (US), recognized for his contributions to the field of polymer science. He holds two patents that showcase his innovative approach to separation media and polymer solutions.
Latest Patents
One of Liguo Song's latest patents is titled "Quasi-interpenetrating networks used as separation media." This invention relates to a quasi-interpenetrating network of polymer chains, which includes linear polyacrylamide (LPA) chains forming a main frame with a weight average molecular weight ranging from approximately 0.05 million to 25 million g/mole. The radius of gyration of these chains is approximately 10 nm to 350 nm. The LPA and polydimethylacrylamide (PDMA) chains are entangled and interpenetrate one another, resulting in a network with substantially no chemical cross-linking.
Another significant patent is "Polymer solution for separation of charged macromolecules by electrophoresis." This invention provides a polymer solution designed for the efficient separation of charged macromolecules through electrophoresis. The solution comprises a plurality of polymers that are entangled to form an interpenetrating network, which offers greater entanglement times than corresponding homopolymers of the same length. The preferred polymers include PAM and PVP or PDAM and PVP, enabling at least a 500-base read length in one run for single-stranded DNA separation.
