Amphiphilic modification and asymmetric silica encapsulation of hydrophobic Au-Fe3O4 dumbbell nanoparticles.
A facile method is developed for amphiphilic surface modification and asymmetric silica encapsulation of hydrophobic Au-Fe3O4 dumbbell nanoparticles. The obtained asymmetric Janus nanocomposites display tunable wettability, enhanced catalysis and better cell internalization as compared to those with complete silica encapsulation.
