The Turkevich method is straightforward and involves the following steps: 1. Dissolve chloroauric acid in water to form a gold precursor solution. 2. Heat the solution to a specific temperature. 3. Add sodium citrate to the heated solution, which acts as both a reducing agent and a stabilizer. 4. The sodium citrate reduces the gold ions to gold atoms, which nucleate to form nanoparticles. 5. The nanoparticles grow until the citrate ions cap them, preventing further growth and stabilizing the solution.
