Abdelhak Maghchiche, Yes, nanotechnology can be effectively integrated with plant residue valorisation to enhance both the extraction and delivery of bioactive compounds. In the extraction process, nanomaterials such as magnetic nanoparticles and nano-sorbents can selectively bind and isolate valuable phytochemicals, improving both yield and purity. Additionally, nano-assisted techniques like ultrasound- or microwave-assisted extraction can increase efficiency while reducing solvent usage and processing time. For delivery, nanocarriers such as liposomes, polymeric nanoparticles, and nanoemulsions can protect sensitive bioactive compounds, enhance their bioavailability, and allow controlled or targeted release. These approaches are particularly useful for stabilising and delivering poorly soluble or unstable plant-derived compounds. Overall, integrating nanotechnology with plant residue valorisation adds significant value to agricultural waste streams and supports sustainable, circular bioeconomy models in fields like agriculture, food, and pharmaceuticals.
