Developing non-toxic nanomaterials involves several key steps:
1. Material Selection: Choosing inherently non-toxic materials such as those mentioned above. 2. Surface Modification: Functionalizing surfaces to enhance biocompatibility and reduce toxicity. For example, coating nanoparticles with polyethylene glycol (PEG) can reduce protein adsorption and immune recognition. 3. Size and Shape Control: Engineering nanoparticles with specific sizes and shapes to optimize their interaction with biological systems and minimize toxicity.
