摘要
Phospholipids, as fundamental building blocks of the cell membrane, play important roles for molecule transportation, cell recognition, etc. However, due to the structural diversity and amphipathic nature, there are few methods for the specific recognition of lipids as compared to other biomolecules such as proteins and glycans. Herein, we developed a molecular imprinting strategy for controllable imprinting toward the polar head of phospholipid exposed on the surface of cellular membranes for recognition. Phosphatidylserine, as unique lipid on the outer membrane leaflet of exosome and also hallmark for cell apoptosis, was imprinted with the developed method. The phosphatidylserine imprinted materials showed high efficiency and specific targeting capability not only for apoptotic cell imaging but also for the isolation of exosomes. Collectively, the synthesized molecularly imprinted materials have great potential for selective plasma membrane recognition for targeted drug delivery and biomarker discovery.
