Synthesis of Gadolinium-based Nanostructures Through an Enzymatic Liposome-controlled Reaction

Abstract

The success of synthesis of varied nanostructures requires the precise precipitation of materials at particular location. Here, gadolinium carbonate nanocapsules or macroporous structures have been successfully synthesized via interplay control on enzymatic precipitation and liposome templating. The nanostructures reflected the shape of the liposomes, where spherical 560 nm size and porous architectures with large pores of 200–300 nm diameter (corresponding to sections along liposomes) ensembles were formed. The manipulation over location of ureases in the liposome system and the temperature-actuated vesicle permeability were crucial factors in determining the morphology of the final product. This liposome-directed enzymatic precipitation represents a powerful yet facile method for lanthanide-based nanostructures synthesis for promising applications.
