Electrochemical Monitoring of Metallic Materials' Surfaces with Biofilm Formation

摘要

Biofilms formed on materials by bacterial activity cause many engineering problems. It ranges from those at hospitals to toilets and kitchen at homes in various ways. To solve those problems, it is very important to analyze the phenomenon precisely and also to monitor the formation and growth process. To achieve the purpose, we have had many proposals for biofilm sensors so far. However, there are not so many proposals for rapid, easy and industrial biofilm sensors. In this research, we established the electrochemical system to monitor biofilm formation and growth to measure the equilibrium (static) potential and also dynamic polarization curves of metallic materials. And we discussed on how we should apply the results to evaluate biofilms on metallic materials.
