Designing multifunctional nanomaterials involves a combination of synthesis techniques and engineering approaches. Researchers use methods like sol-gel process, chemical vapor deposition, and electrospinning to create these materials. The design process often involves selecting appropriate nanocomponents and integrating them to achieve the desired multifunctionality. For example, a nanomaterial intended for cancer therapy might combine a drug-loaded nanoparticle with a targeting ligand and an imaging agent.
