Studies by M.L. Yao and Co-Authors Describe New Findings in Enzymes and Coenzymes (Enzyme-Polymer Hybrid Nanocatalyst Prepared by Microemulsion Polymerization)

By a News Reporter-Staff News Editor at Life Science Weekly -- New research on Enzymes and Coenzymes is the subject of a report. According to news reporting out of Jiangsu, People's Republic of China, by NewsRx editors, research stated, "An inverse microemulsion polymerization was used to encapsulate lipase in polymer nanoparticles."

Our news journalists obtained a quote from the research, "The utilization of a non-ionic surfactant, polyoxyethylene-4-lauryl ether, in combination with sodium bis-2-ethylhexylsulfosuccinate reduced the charge density at the interfacial region of the microemulsion and thus favored the activity of lipase accommodated at the interfacial region of the microemulsion. At the optimized condition, 73.8 and 88.6 % of the original activity for lipase encapsulated in polyacrylamide and poly(N-isopropylacrylamide) (PNIPAM) nanoparticles were obtained."

According to the news editors, the research concluded: "The lipase encapsulated in polyacrylamide nanoparticles exhibited a tenfold increase in the half-life time of enzyme activity at 50 A degrees C. The temperature-responsive property of PNIPAM provided a temperature-controlled activity for the encapsulated lipase."
