摘要

通过将Celgard-2400膜暴露于氨血浆中,将氨基添加到膜表面。用衰减全反射傅立叶变换红外光谱仪和俄歇电子能谱仪检测了表面上存在的氨基。通过这些氨基,白蛋白附着在细胞膜上。在一些实验中,附着的白蛋白通过与戊二醛交联进一步稳定。研究了生理盐水和血浆洗涤对白化膜的影响。我们观察到,在最初的白蛋白洗脱后,附着白蛋白的浓度趋于平稳。保留在膜上的白蛋白的量在275到357微克/平方厘米之间变化。

Albuminated polymer surfaces for biomedical application.

Amino groups were added on to the surfaces of Celgard-2400 membranes by exposing them to an ammonia plasma. The presence of amino groups on the surfaces was detected by an attenuated total reflection Fourier Transform infrared spectrometer and by the Auger electron spectrometer. Through these amino groups, albumin was attached to the membranes. In some experiments, the attached albumin was further stabilized by cross-linking with glutaraldehyde. The effect of washing the albuminated membranes with saline and with plasma was investigated. It was observed that after the initial wash-out of albumin, the concentration of attached albumin tends to level off. The amount of albumin retained on the membranes varied between 275 to 357 micrograms/cm2.
