Description du projet
Des nanopoints de carbone dérivés de petites molécules pour des applications complexes
Les nanopoints de carbone sont des nanoparticules sphériques qui se composent d’un noyau défini et d’une enveloppe fonctionnelle externe pouvant être conçue de manière rationnelle par des approches chimiques spécifiques. Les scientifiques du projet e‑DOTS, financé par l’UE, souhaitent faire progresser la conception et le processus de production des nanopoints de carbone afin d’étendre leurs applications. Pour ce faire, ils élucideront le mécanisme qui sous‑tend la conversion des petites molécules en nanoparticules et concevront des nanopoints de carbone aux propriétés uniques. Ces nanoparticules conçues trouveront leur application dans des défis technologiques et biologiques tels que la bioimagerie de haute qualité et la catalyse de l’eau.
Objectif
e-DOTS takes advantage of nanoscale and process-intensification principles, information technology and automation/robotics to translate molecular properties to nanoparticles for use in technologically advanced challenges, ranging from high-quality bioimaging to green catalysis in water.
A stringent molecular control over the synthesis and multivalent properties of “carbon nanodots”, 2-5 nm spherical nanoparticles, will allow us to shape a nanofabrication space with engineered functions. The core-shell structure of carbon nanodots, consisting of a confined core and an outer functional shell can be rationally designed by controlled chemical approaches and by a tailored choice of the proper starting materials.
e-DOTS scientific objectives are planned to go beyond the state of the art, with the aim to:
(i) elucidate the mechanism and the structural details in the conversion of small molecules to nanoparticles;
(ii) expand the carbon nanodots preparation process window and allow its automated exploration, directed at ambitious targets;
(iii) design and prepare carbon nanodots with tailored properties – in terms of size, charge, luminescence, chirality, and outer-shell functions – outperforming current technologies in green catalysis and biomedical imaging.
(iv) investigate and ensure the safety profile of carbon nanodots in a safe-by-design approach.
e-DOTS is a highly interdisciplinary project, based on frontier methods that the Prato group has successfully designed for the molecular modification of very diverse carbon nanostructures. Delving into fundamental aspects of carbon nanodots will allow to unfold their full potential in technological and biological applications.
e-DOTS will thus offer unprecedented opportunities to the scientific community, since the specific molecular properties of the reactants can be transferred, combined and enhanced up to the nanoscale, yielding carbon nanodots tailored to function.
