To form polymer-templated gold nanoparticles, aqueous stock solutions of polymer and gold(III) chloride trihydrate (HAuCl4) solution were prepared, each at 2wt% concentration, and separately adjusted to pH 7. Nanoparticle formation was monitored by UV-vis, with the measurement taken before and after the addition of gold solution, every hour in the following 8 hours, and then at 24 hours and 48 hours after addition.
