There are several methods to achieve targeted delivery in catalysis:
1. Encapsulation: Catalysts can be encapsulated within nanoparticles or microparticles, which can then be directed to the reaction site. These encapsulating materials can be engineered to release the catalyst under specific conditions. 2. Surface Functionalization: Catalysts can be attached to surfaces that are designed to interact with specific reactants or reaction environments. 3. Carrier Systems: Use of carrier molecules or systems that can transport the catalyst to the desired location. Examples include micelles, dendrimers, and polymer-based carriers. 4. Magnetic Targeting: Magnetic nanoparticles can be used to transport the catalyst to the reaction site using an external magnetic field.
