Sonication assisted assemblage of exotic polymer supported nanostructured bio-hybrid system and prospective application

• Sonication assisted immobilization of porcine pancreatic lipase (PPL).
• Immobilized onto PEG-silver/iron oxide (PEG-Ag/IO) hybrid nanoparticles.
• Assemblage of antibacterial and magnetically recyclable PPL loaded PEG-Ag/IO nanorods.
• Increased activity, thermostability and storage stability of the immobilized PPL.
• Development of detergent compatible (for oil de-staining) system.

This work was focused on sonication mediated immobilization of porcine pancreatic lipase (PPL) onto poly(ethylene glycol) supported silver-iron oxide hybrid nanoparticles (PEG-Ag/IONPs). Selected process parameters of sonication were optimized using response surface methodology. Sonication assisted assemblage of spherical PEG-Ag/IONPs and consequent evolution of nanorods post PPL immobilization were documented. The efficacy of the reported immobilization strategy was attested by the increased thermostability, storage stability and enhanced activity of the biocatalyst, suggestive of plausible structural modulations post immobilization. The commercial prospect of the antibacterial and magnetically recyclable system was vouched by its excellent compatibility with some commercial detergents for oil de-staining.
