This invention relates to a three-dimensional
scaffold based on
chirality and peptides for selective
cell adhesion, its preparation method, and its applications, relating to the field of medical products. The three-dimensional
scaffold is a stacked, three-dimensional ordered structure, with each layer comprising several ordered
polyelectrolyte multilayer membrane soft carriers arranged at an angle between adjacent
layers. Each layer of the
polyelectrolyte multilayer membrane is formed by alternating deposition of positively charged chiral molecules grafted with specific recognition groups and negatively charged supramolecular polyelectrolytes on the soft carriers, followed by modification with peptides. The two peptides in adjacent
polyelectrolyte multilayer membranes are different and are used to promote the specific adhesion of different cells. The three-dimensional
scaffold provided by this invention has specific adhesion properties, thereby avoiding excessive
cell proliferation in incorrect locations and helping to prevent problems such as re-injury and
stenosis of artificial blood vessels.
