** ** **Following thermal clustering of gold nanoparticles with in situ UV-Vis and how to control their hysteresis behavior** **** **** Hysteresis is an essential attribute of many solid-state devices and biological processes, yet it is often overlooked in colloidal and soft-matter dynamic systems. Herein we show that gold nanoparticles can remain dispersed or aggregated at the same temperature depending on the trajectory of applied stimulus, featuring hysteretic behavior. Aided by real-time analytics and fine tuning of experimental parameters, such as salt concentration, nanoparticle diameter and surface potential, we disentangled kinetic (rate-dependent) and thermodynamic (rate-independent) component of hysteresis in cyclic clustering of nanoparticles. Our findings enrich the repertoire of experimental framework suitable for study life-like features on purely synthetic settings. \---------- Please **REGISTER** for PhD Mid-term Seminar Series on Jun 8, 2020 11:00 AM CEST at: [https://attendee.gotowebinar.com/register/7273286317752548363](https://attendee.gotowebinar.com/register/7273286317752548363) After registering, you will receive a confirmation email containing information about joining the webinar.
