Platinum Nanoparticles Encapsulated by Aminopeptidase: A Multifunctional Bioinorganic Nanohybrid Catalyst

Two birds with one stone: When platinum nanoparticles are encapsulated by a bacterial aminopeptidase, the novel hybrid combines platinum-catalyzed hydrogenation and peptidase-catalyzed hydrolysis for multistep synthesis (see picture). This concept of bioinorganic integration can be extended to various enzymes and inorganic materials, allowing for the design and fabrication of novel multifunctional materials.
