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.
