Stimuli can induce various responses in nanomaterials, including:
1. Structural Changes: Nanomaterials can undergo morphological transformations when exposed to specific stimuli. For example, temperature changes can cause phase transitions in materials like shape-memory alloys. 2. Chemical Reactions: Stimuli such as light or pH can trigger chemical reactions that alter the composition or functionality of nanoparticles. 3. Optical Properties: Light stimuli can change the optical properties of nanomaterials, making them useful for applications in photonics and sensing. 4. Magnetic Properties: Magnetic fields can align magnetic nanoparticles, enhancing their utility in magnetic resonance imaging (MRI) and other biomedical applications.
