Eco‐friendly biomolecule‐nanomaterial hybrids as next‐generation agrochemicals for topical delivery

The agrochemical is often applied to enhance the agricultural production. Nanotechnology has advanced agricultural biotechnology in the new "agri-tech revolution." Eco-friendly nanoparticles as carriers can essentially actualize the application of biomolecules as sustainable agrochemicals to increase their biological performance and reduce deterioration of the ecosystem. Particularly, these nanocarrier-biomolecule hybrids will be ideal for topical applications to enhance the crop yield and quality. This review summarizes the current efforts in developing nanoparticles as carriers of biomolecules for topical delivery. First, the applicable biomolecules for plant growth regulation and the pathogen control are briefly introduced. The criteria and strategies for research and industrial development of nanocarrier-biomolecule hybrids are then proposed, which better involves both researchers and manufacturers in the beginning for an efficient R&D process. The review further discusses several typical nanoparticle-biomolecule hybrids as the candidates of next-generation agrochemicals with advanced scientific merits and high perspectives of industrialization as the conclusion.
