Purification plays a critical role in dictating the observed physico‐chemical and optical properties of nanomaterials. In article number 2000119, Rafik Naccache and co‐workers propose a simple and elegant approach to monitor the purification endpoint towards achieving uniform optical properties of carbon dots. The approach can be easily extended towards the purification of other hydrophilic nanomaterials.
