This work reports a solution-based method for on chip growth of wrinkled gold nanoparticles. During the growth process, time-resolved scattering profiles were measured, which permitted one to collect information regarding the growth kinetics. Finally, using the fabricated substrate, a 30 times stronger SERS enhancement was achieved than a spherical nanoparticle immobilized substrate.
