Although the formation mechanism of biogenically metallic nanoparticles is broadly associated to enzyme mediation, major attention has been given to the role of proteins and peptides in oxido-reduction of metallic ions leading to these nanostructures. Among the wide range of biomolecules that can act not only as capping agents but also as non-enzymatic agents to form nanoparticles, disulphide bridge-containing...
We have demonstrated that gold nanoparticles (AuNPs) can effectively associate with enzyme through spontaneous adsorption to afford supramolecular complexes, resulting in a significant increase of its enzymatic activity. In this work, we embarked on a study of the interactions between the different-sized AuNPs and the substrate through quantifying the kinetic parameters (Kcat and KM). The diversity...
Summary form only given. Noble metals nanoparticles can be applied to a wide range of functions such as catalysis, optics and biosensing. Although chemical and physical synthetic routes to noble metal nanoparticles have been extensively developed, another possibility is synthesis by bioreduction of noble metal ions using microorganism. For microbial synthesis of noble metal nanoparticles, we focused...
