The physical properties of a series of composite gels, including the critical micelle concentration (CMC), particle sizes, zeta potential, rheological behavior, morphology of composite gels, and sol gel transition, were characterized in vitro.
The use of composite gels improved the adherence of cells.
Synchronously, tetracycline hydrochloride (TH) was encapsulated into GMs to enhance bioactivity of composite gel scaffolds.
Therefore, it was obvious that sol-gel-sol transition behavior of composite hydrogel depended on the composition of the PECE and Pluronic F127 hydrogel.
Only Pluronic F127, a composition of composite hydrogel, was remained in the HK micelles, which would not affect in vitro release behavior of composite hydrogel.
The biocompatibility of the composite gels was validated by hemolysis test.
The fracture behaviors of composite materials exhibit similar trends.
The presence of fibrin in composite gels was confirmed by immunogold staining of the composite fibrin/collagen gels.
The presence of fibrin in the composite gels was confirmed by immunogold staining of the fibrin/Col I gels.
To evaluate the rheological properties of the composite gel, the storage modulus (G′), loss modulus (G″), and shear recovery capability of the gel were characterized using oscillatory rheology.
