Abstract

The preparation of nanoparticles and their targeted connection with other functional units is one keychallenge in developing nanoscale devices. Herein, we report an experimental strategy toward thedevelopment of anisotropic nanoparticle architectures. Our approach is based on phase separation ofbinary mixed polymer brushes on gold nanoparticle surfaces leading to Janus-type structures, as revealedby scanning transmission electron microscopy and electron energy-loss spectroscopy and, additionally,corroborated by computer simulation. We show that such structures can be used for the site-selectivefunctionalization with additional nanosized entities.
