Several factors can contribute to the instability of nanomaterials:
Environmental Conditions: Factors such as temperature, humidity, and exposure to light can cause nanomaterials to degrade or change over time. Chemical Interactions: Nanomaterials can react with chemicals in their environment, leading to changes in their composition or structure. For example, oxidation can alter the properties of metallic nanoparticles. Mechanical Stress: Physical forces such as pressure, bending, or stretching can cause nanomaterials to deform or break. Aggregation: Nanoparticles tend to aggregate or clump together, which can affect their size distribution and properties.
