The development of personalized coatings involves several steps: 1. Material Selection: Choosing the appropriate base material (e.g., glass, plastic) that will be coated. 2. Functionalization: Applying chemical or biological molecules to the surface to achieve desired properties, such as hydrophilicity or specific binding sites for antibodies. 3. Testing and Optimization: Conducting rigorous testing to ensure the coating performs as expected under various conditions and refining the formulation as needed.
