Controlled Nanoparticle Formation by Enzymatic Deshelling of Biopolymer‐Stabilized Nanosuspensions

Formation of biopolymer‐stabilized nanosuspensions followed by dextranase enzyme treatment is demonstrated for the liberation of monodisperse particles of controllable size up to 6 nm (see image). A range of metal oxide nanoparticles stabilized by remnant oligomer at ≈3 wt% are reliably prepared for...

description Formation of biopolymer‐stabilized nanosuspensions followed by dextranase enzyme treatment is demonstrated for the liberation of monodisperse particles of controllable size up to 6 nm (see image). A range of metal oxide nanoparticles stabilized by remnant oligomer at ≈3 wt% are reliably prepared for applications that include catalysis and nanoparticle‐based biosensors.
