Multimodal resins combine multiple interaction mechanisms, such as hydrophobic, ionic, and hydrogen bonding, to provide versatile and selective binding capabilities. 

These resins are designed to enhance the purification and separation of complex biomolecules by leveraging different modes of interaction, allowing for more efficient and robust processes in protein and antibody purification.

 Their multifunctional nature makes them particularly useful in challenging applications where single-mode resins may fall short.
