摘要: We report on the synergy between catalytic propulsion and mesoporous silica nanoparticles (MSNPs) for design of Janus nanomotors as active cargo delivery systems with sizes <100 nm (40, 65, 90 nm). The asymmetry is given by electron beam (e-beam) deposition a very thin platinum (2 nm) layer MSNPs. chemically powered present diffusion at low H2O2 fuel concentration (i.e., <3 wt %). Their apparent coefficient enhanced up to 100% compared their Brownian motion. Due architecture small dimensions, they can load molecules in large quantity serve nanocarriers directed chip.
