• (CNTs) by growing dendrimers on their surface. First, CNTs were pre-functionalized with maleic acid (MA) via Diels–Alder reaction in presence of a deep eutectic solvent under ultrasonication. Subsequently, dendrimers of varying length were grown by the repeated reaction of ethylene diamine and MA. Raman

• morphology, yield and monodispersity. The introduction of a deep eutectic solvent as a cost-effective and green solvent was reviewed, where the usage of these solvents enabled the extraction and formation of desired nanostructures. The work also records the advantages and disadvantages of wet chemical

• reduction methods which use surfactants, and explores the in vitro and in vivo cytotoxicity of the synthesized anisotropic nanoparticles. A portion of the work looks into the possible integration of nanotechnology in deep eutectic solvent extractions and also the use of carrageenan as a safe stabilizing

After encapsulation with graphene sheets the cathode had a discharge capacity of 215 mAh·g−1 at 2C after 2000 cycles. In another chemical method, S NPs were precipitated on rGO from a deep eutectic solvent
