Freestanding protein films are interesting for many applications ranging from microencapsulation to tissue engineering. Here, the authors use interfacial rheology to characterize the adsorption kinetics and the rheology of spider-silk films formed at an oil water interface. The high surface activity of the engineered spider-silk proteins results in a fast formation of highly stable films, which can be modified by the addition of phosphate ions to the solution.
自支撑蛋白质薄膜在许多应用中都很有趣，从微封装到组织工程。在这里，作者利用界面流变学来描述蜘蛛丝蛋白在油水界面吸附的动力学和流变特性。工程化蜘蛛丝蛋白具有很高的表面活性，导致其能够快速形成高度稳定的薄膜，并且可以通过向溶液中添加磷酸根离子来对其进行修饰。
