A Polymer brush is a surface coating consisting of polymers tethered to a surface, where the tethered polymer chains completely fill up the space available. It is well known that the polymer burst surface of materials could repel bacteria, water molecules etc. However, biofilms might change the beneficial property. Then the characteristics might be lost. Actually, we confirmed that some materials having water repellent surfaces often lose their water repellency with biofilm formation. In this experiment, we focused on the two kinds of bacteria, E.coli and S. epidermis, since they are representative bacteria in our human bodies. In addition, they are gram negative and gram positive bacteria, respectively. Using these bacteria, we observed the effect of polymer brush on biofilm formation by the bacteria. The evaluation methods for biofilms were mainly Raman spectroscopy and staining by crystal violet.
