Self-assembling of nanocubes and nanoparticles

Today various nano-moieties including nanoparticles, nanocubes, nanosticks, nanoflowers and nanoprimes have been synthesised. It is an interesting challenge to build nanostructures using those nano-moieties as blocks owing to their distinct properties and numerous applications. Herein, we demonstrate a smart way, self-assembling, to arrange nanoparticles and nanocubes into a line, sphere, network, bowl-bottom etc. The obtained anisotropic nanostructures have been employed to enhance the sensor sensitivity and to identify the hot-spot position for surface-enhanced Raman scattering (SERS).
