在当前的研究中，提出了一种详细测定受贻贝启发的聚合物薄膜划痕愈合效率的新方法。为此，将传感器分子纳入基于可逆组氨酸锌相互作用的自修复聚合物网络中。监测传感器分子的荧光，通过共焦激光扫描显微镜（CLSM）对愈合效率进行详细的深度和时间分辨测定。最后，这个概念代表了一种用于确定聚合物薄膜划痕自修复效率的有效且详细的方法，并且也可以应用于其他基于可逆动态键的划痕自修复系统。
Within the current study, a novel approach for the detailed determination of the scratch healing efficiency in mussel-inspired polymer films is presented. For this purpose, a sensor molecule was incorporated into a self-healing polymer network based on reversible zinc histidine interactions. The fluorescence of the sensor molecule was monitored enabling a detailed depth- and time-resolved determination of the healing efficiency by means of confocal laser scanning microscopy (CLSM). Finally, this concept represents an efficient and detailed approach for the determination of the scratch self healing efficiency in polymer films and can also be applied for other scratch self-healing systems, which are based on reversible dynamic bonds.
