Therefore, crosslinking is essential to prepare the mentioned scaffolds. ɣ -Glycidoxypropyltrimethoxysilane (GPTMS) was added to polymeric solutions as a cross-linker agent and then freeze-dried. Scanning electron microscopy (SEM) micrographs indicated that the average pore size of the G-GPTMS and HEC-GPTMS was 54 and 120 µm, respectively. According to the dynamic rheology measurements (DMA), both solutions were flowable in which, the loss modulus was higher than the storage one in HEC-GPTMS and G-GPTMS did not have storage modulus. These loose structures might be depending on the formation of water molecules during sol-gel reaction. Moreover, HEC-GPTMS revealed shear thinning behavior and G-GPTMS showed shear thickening behavior. The G-GPTMS sample showed lower swelling ratio and degradation degrees as compared to HEC-GPTMS scaffold. But due to hydrophilicity and macroporous structures, both scaffolds showed 1700% swelling ratio.Tissues and Biomaterial Research Group (TBRG)-USERNJournal of Tissues and Materials2645-34873320200901The Effect of Conductive Biomaterials on the Tissues Engineering12254210.22034/jtm.2020.122542ENJournal Article20210115Tissues and Biomaterial Research Group (TBRG)-USERNJournal of Tissues and Materials2645-34873320200901Recent Advances on the Organ-on-Chip Devices: Focus review12254310.22034/jtm.2020.122543ENJournal Article20210115
