Title : ZnO nanoparticles: Eco-frienldy synthesis, functionalizations and applications


ZnO nanoparticles (NPs) are extensively used for many applications, due to their properties such as wide direct-band-gap, high exciton binding energy, high UVA and UVB optical absorption, piezoelectricity, intrinsic fluorescence as well as their biocompatibility. The achievement of ZnO-NPs using eco-friendly conditions is of outmost importance in the perspective of an ecological transition and circular bioeconomy. Synthetic strategies will be analysed, aiming at tuning the structural, morphological and spectroscopic properties, to mould target application. In this framework, procedures were optimized, using shear precipitation methods in aqueous solutions, and at temperatures as low as 40°C, during synthesis and drying phases, without any additional treatments. Morphology oriented, innovative synthesis of the ZnO-NPs were pursed using non-toxic, newly planned deep eutectic solvents (DES). Further functionalization was carried out to tailor ZnO properties towards specific applications. Silanization procedures were set out to enhance the ZnO fluorescence response and to create a link with chlorinated pesticide for sensing purposes. Detection of penconazole was achieved as decreasing fluorescence signal of APTMS-coated ZnO-NPs as a function of increased concentration, with a LOD of 0.1 ppm. Low temperature one-step coating of ZnO-NPs with mimetic molecules ensured the achievement of integrated systems for soil priming, allowing better growth and well-being of test plants, such as vicia faba.
