Reports on Enzymes and Coenzymes Findings from Hong Kong Polytechnic University Provide New Insights (A General Strategy for Site-Directed Enzyme Immobilization by Using NiO Nanoparticle Decorated Mesoporous Silica)

By a News Reporter-Staff News Editor at Life Science Weekly -- Investigators publish new report on Enzymes and Coenzymes. According to news originating from Hong Kong, People's Republic of China, by NewsRx correspondents, research stated, "Mesoporous materials have recently gained much attention owing to their large surface area, narrow pore size distribution, and superior pore structure. These materials have been demonstrated as excellent solid supports for immobilization of a variety of proteins and enzymes for their potential applications as biocatalysts in the chemical and pharmaceutical industries."

Our news journalists obtained a quote from the research from Hong Kong Polytechnic University, "However, the lack of efficient and reproducible methods for immobilization has limited the activity and recyclability of these biocatalysts. Furthermore, the biocatalysts are usually not robust owing to their rapid denaturation in bulk solvents. To solve these problems, we designed a novel hybrid material system, mesoporous silica immobilized with NiO nanoparticles (SBA-NiO), wherein enzyme immobilization is directed to specific sites on the pore surface of the material. This yielded the biocatalytic species with higher activity than free enzyme in solution."

According to the news editors, the research concluded: "These biocatalytic species are recyclable with minimal loss of activity after several cycles, demonstrating an advantage over free enzymes."
