Polymeric Nanoparticles Decorated with Monoclonal Antibodies: A New Immobilization Strategy for Increasing Lipase Activity
2021
Recent advances in nanotechnology techniques enable the production of polymeric nanoparticles with specific morphologies and dimensions and, by tailoring their surfaces, one can manipulate their characteristics to suit specific applications. In this work we report an innovative approach for the immobilization of a commercial lipase from Candida rugosa (CRL) which employs nanostructured polymeric carriers conjugated with anti-lipase monoclonal antibodies (MoAbs). MoAbs were chemically conjugated on the surface of polymeric nanoparticles and used to selectively adsorb CRL molecules. Hydrolytic enzymatic assays evidenced that such immobilization technique afforded a significant enhancement of enzymatic activity in comparison to the free enzyme.
