AMROBS ll-metal replicas of biological (and technical) surfaces - A deeper look into the verfication of the method

The research presented in this work deals with the topic of testing the reproducibility of the all-metal replicas of biological (and technical) surfaces (AMROBS) approach [1]. These replicas display replication accuracies down to the microscale, while presenting durable and conductive elements for easy surface testing and modifications. Already established techniques like silicone casting, TOLLENS reaction and copper electroplating are combined to achieve these highly accurate all-metal replicas. Scanning electron microscopy and white-light interferometry are used for analysis. The goal of this work is to test a variety of different surface morphologies in regards to reproducibility by comparing the all-metal replicas to their original counterparts. In the end of this work, the verified methodology is applied to complex biological samples, which will allow for even more sophisticated applications of the AMROBS approach.
