Grafting of aryldiazonium cations bearing a p-mannoside functionality over microbial fuel cell (MFC) anode materials was performed to investigate the ability of aryl-glycoside layers to regulate colonisation by biocatalytic biofilms. Covalent attachment was achieved via spontaneous reactions and via electrochemically-assisted grafting using potential step experiments. The effect of different functionalisation protocols on MFC performance is discussed in terms of changes in wettability, roughness and electrochemical response of modified electrodes. Water contact angle measurements (WCA) show that aryl-mannoside grafting yields a significant increase in hydrophilic character. Surface roughness determinations via atomic force microscopy (AFM) suggest a more disordered glycan adlayer when electrografting is used to facilitate chemisorption. MFCs were used as living sensors to successfully test the coated electrodes: the response of the MFCs in terms of start-up time was accelerated when compared to that of MFC equipped with non-modified electrodes, this suggests a faster development of a mature biofilm community resulting from aryldiazonium modifications, as confirmed by cyclic voltammetry of MFC anodes. These results therefore indicate that modification with glycans offers a bioinspired route to accelerating biofilm colonisation without any adverse effects on final MFC outputs.

带有p的芳基重氮阳离子的接枝进行了微生物燃料电池（MFC）阳极材料上的甘露糖苷功能研究，以研究芳基糖苷层通过生物催化生物膜调节定居的能力。共价连接是通过自发反应和使用潜在步骤实验通过电化学辅助接枝实现的。根据润湿性，粗糙度和修饰电极的电化学响应的变化，讨论了不同功能化方案对MFC性能的影响。水接触角测量（WCA）表明，芳基甘露糖苷接枝可显着提高亲水性。通过原子力显微镜（AFM）进行的表面粗糙度测定表明，当使用电接枝促进化学吸附时，聚糖的无序层更加混乱。MFCs被用作生活传感器，以成功测试涂覆电极：与配备非修饰电极的MFC相比，MFCs在启动时间方面的响应速度加快，这表明成熟的生物膜群落发展更快如MFC阳极的循环伏安法所证实的，是由芳基重氮修饰产生的。因此，这些结果表明，用聚糖修饰提供了一种生物启发的途径来加速生物膜的定殖，而对最终的MFC输出没有任何不利影响。如MFC阳极的循环伏安法所证实的。因此，这些结果表明，用聚糖修饰提供了一种生物启发的途径来加速生物膜的定殖，而对最终的MFC输出没有任何不利影响。如MFC阳极的循环伏安法所证实的。因此，这些结果表明，用聚糖修饰提供了一种生物启发的途径来加速生物膜的定殖，而对最终的MFC输出没有任何不利影响。
