Abstract (EN): Carbon nanomaterials, for example, carbon, quantum, and graphene dots, owe their chemical and physical properties mostly to the functional chemical groups present at their surface. As such, modulation of those functional groups will allow improvements in carbon nanomaterials, tailoring the desired properties, while at the same time minimizing unwanted features, which are essential for applications in the most diverse scientific areas. Overall, depending on the surface modification of the functional groups, by inserting new ones or replacing others already bonded, it is possible to increase the carbon nanomaterials¿ physical stability by reducing the van der Waals interactions and, thus, agglomeration of the nanomaterials, while also increasing biological compatibility and improving optical properties. This chapter will explore different approaches employed for the engineering of functional groups on those nanomaterials surface, such as covalent bonding and noncovalent adsorption of small molecules and endohedral filling of the nanomaterial empty inner cavity, among others, as well as the impact of such surface modifications on the physical¿chemical properties of the carbon-based nanomaterials. © 2024 Elsevier Ltd.
