Researchers at the Hebrew University of Jerusalem found that organic molecules significantly influence the redox potential of gold nanoparticles. This study used experiments and computer simulations to show how different capping agents affect the nanoparticles’ electrochemical properties. The results demonstrated that these molecules can change the electrical behavior of gold nanoparticles by up to 71 millivolts, offering insights into their applications in fields like catalysis, electronics, and drug delivery. The study highlights the importance of capping agents in tuning nanoparticle behavior for specific uses.
