title: The procoagulant properties of hyaluronic acid-collagen (I)/chitosan complex film.
abstract: Biomaterial-induced human platelet activation remains one of the most crucial factors to determine the procoagulant properties of the biomaterial. In this experiment, a new type of biomacromolecule complex film (hyaluronic acid-collagen (I)/chitosan, HCC) was prepared using the electrostatic self-assembly method. Then the procoagulant properties of this complex film were characterized. Based on the nano-resolution of atomic force microscopy, the platelet-derived microparticles (PMPs) that present the activation of platelets were clearly visualized on the membrane surface of platelets for the first time, and the measurement indicated that the size of PMPs is around 50-110 nm. Furthermore, the results of AFM measurement were confirmed by flow cytometry analysis. The expression of CD62P (P-selectin) dramatically increased after the platelet-rich plasma interacted with the biomaterial solution. From the results, we could draw the conclusion that this biomacromolecule complex film has promising procoagulant properties, and has the potential to be practically used as procoagulant material.
