Of late, many synthesis processes have been studied to develop irregular
nano-morphologies of gold nanostructures for biomedical applications in order
to increase the efficacy of nanoparticle theranostics, tune the plasmonic absorbance
spectra, and increase the sensitivity of biomolecule detection through surface
enhanced Raman spectroscopy. Here we report, a novel, non-seed mediated
versatile single pot synthesis method capable of producing hyperbranched gold
“nano-polyvilli” with more than 50–90 branching nanowires propagating from
a single origin within each structure. The technique was capable of achieving
precise tuning of the branch propagation where the branching could be
controlled by varying the duration of incubation, temperature, and hydrogen
ion concentration.
