Controlled Aggregation of Citrate-Stabilized Gold Nanoparticles into Long-Lived Metastable Clusters

The controlled aggregation of plasmonic nanoparticles remains a critical challenge for achieving temporally stable and reproducible colloidal substrates for surface-enhanced Raman scattering (SERS). Here, we show that the antihistamine drug bilastine induces a concentration-dependent, self-limiting aggregation of citra...
