Organophosphorus pesticides are the most extensively utilized agrichemicals in the world. They play a crucial role in regulating crop growth, immunizing against pests, and improving yields, while their unregulated residues exert serious detrimental effects on both the environment and human health. Many efforts have been made in the world to monitor organophosphorus pesticides and solve the issues caused by them.

Lithium metal batteries (LMBs) are distinguished by their elevated energy densities which represent themselves as the formidable contenders for the forthcoming generation of energy storage technologies. Nonetheless, their cycling efficiency is hindered owing to unregulated growth of lithium dendrites and unstable solid electrolyte interphase (SEI). This raises serious safety concerns while rendering LMBs unfeasible for real-world implementation.

Chitosan, a biopolymer derived from chitin, offers significant potential for regulated anticancer drug administration and tissue regeneration growth factors, owing to its biocompatibility, low toxicity, biodegradability, and little immunogenicity. Moreover, its structure can be extensively modified, for example, to create scaffolds, hydrogels, nanoparticles, and membranes, allowing it to be engineered precisely to achieve specific outcomes However, the therapeutic utilisation of chitosan is impeded by significant challenges, such as its inadequate hemocompatibility, durability, and uniformity in commercial manufacturing. Additionally, there is insufficient research offering a thorough examination of the capabilities, limitations, and challenges related to chitosan as carriers for anticancer drugs and growth factors.

Lithium metal batteries (LMBs), with high energy densities, are strong contenders for the next generation of energy storage systems. Nevertheless, the unregulated growth of lithium dendrites and the unstable solid electrolyte interphase (SEI) significantly hamper their cycling efficiency and raise serious safety concerns, rendering LMBs unfeasible for real-world implementation. Covalent organic frameworks (COFs) and their derivatives have emerged as multifunctional materials with significant potential for addressing the inherent problems of the anode electrode of the lithium metal.
