Various types of animal models are used depending on the research question and the type of nanomaterial being studied. Commonly used models include:
Rodents (e.g., mice and rats): These are widely used for preliminary studies due to their small size, ease of handling, and well-characterized genetics. Non-human primates: These are used in more advanced stages of research due to their closer physiological and genetic similarities to humans. Zebrafish: These are increasingly popular due to their transparent embryos, which allow for real-time imaging of nanomaterials. Canines and felines: Used in specific studies related to veterinary applications of nanotechnology.
