In this study, an electro-spun co-polymer PLGA/PCL blend was fabricated using various percentages of PLGA in the blend PLGA/PCL solutions. The PLGA/PCL ratios used to fabricate the electrospun fibrous mats were reflected in the FT-IR (Fourier Transform Infrared Spectroscopy) data. Experimental results from the MTT assay showed that the biocompatibility of the electro-spun co-polymer increased at increasing percentages of PLGA. In vitro cells adhesion and proliferation of fibroblast cells on electro-spun mats were characterized by SEM morphology. In addition, we found that increasing PLGA concentrations affected the mechanical properties of electro-spun membranes and increased the biocompatibility of PLGA/PCL electro-spun fibrous mats.
在这项研究中,使用不同比例的 PLGA 制备了一种电纺共聚物 PLGA/PCL 共混物的 PLGA/PCL 共混物溶液。用于制造电纺纤维垫的 PLGA/PCL 比在 FT-IR(傅里叶变换红外光谱)数据中得到反映。MTT 测定的实验结果表明,随着 PLGA 百分比的增加,电纺共聚物的生物相容性增加。通过 SEM 形态学对成纤维细胞在电纺垫上的细胞粘附和增殖进行了研究。此外,我们发现增加 PLGA 浓度会影响电纺膜的机械性能并提高 PLGA/PCL 电纺纤维垫的生物相容性。
