Self degrading nanomaterials are designed to break down through various mechanisms, including:
1. Hydrolysis: Water molecules break the chemical bonds in the nanomaterial, leading to its degradation. This is common in polymers like polylactic acid (PLA). 2. Enzymatic Action: Enzymes naturally present in the body or environment can catalyze the breakdown of the nanomaterial. 3. Photodegradation: Exposure to light, particularly UV radiation, can trigger the breakdown of certain nanomaterials. 4. Redox Reactions: Oxidation-reduction reactions can lead to the degradation of metals and other materials.
