The interest in carbon-based nanomaterials, such as carbon-nanodots and graphene, has grown exponentially because these materials have unique properties and applications in the medical, electronic, clean energy and several other fields for biochemical sensing, energy conversion, photocatalysis, optoelectronics, etc. Carbon dots were discovered in 2004, yet very little research has been done on the colloidal stability thereof. Nanomaterials such as carbon dots will inescapably make their way to natural waters with an unknown environmental fate. Therefore, it is of great importance to understand the behaviour of carbon dots under the influence of certain environmental conditions such as pH, ionic strength, and in the presence of natural organic matter.
