“…Microscopic observations show that biofilms can have complex structures such as voids, cavities and channels, where nutrients can flow [12]. In spite of these complex structures, a wide number of studies in the literature consider diffusion as the main mass transport through the biofilm [13][14][15][16][17][18].…”

Biofilms on metal surface in an aqueous environment is a complex electrochemical system. The heterogeneous electrochemical characteristics of biofilm/metal interface and local electrochemical techniques used for this purpose are discussed in this work. The techniques presented in this work include microelectrode, scanning vibrating electrode, the wire beam electrode method, and scanning electrochemical microscopy. Two potentially useful techniques, localized electrochemical impedance spectroscopy and scanning Kelvin probe force microscopy, are also discussed. The advantages and limitations of these techniques are summarized. A new approach: numerical simulation of micro-electrochemical heterogeneity of biofilm covered metals is introduced.

Biofilms are a self‐organized, self‐structured community of microorganisms that are enclosed in a self‐produced polymeric matrix. Due to the intrinsic complexity of biofilms, their artificial preparation has remained a challenge despite practical usefulness as reservoirs for biocatalysts. Herein, autonomously generated artificial biofilms termed BIOMOSAIC (BioInspired, Oxygen‐induced Microbial Organization through Self‐Assembly at the air/liquid Interface as a Catalyst) films are reported. Similar to bacterial homing, a large number of cells are spontaneously recruited and immobilized into the film, which is autonomously generated at air/liquid interfaces by simple mixing of phenolic polyamine and tyrosinase‐expressing Pseudomonas fluorescens. BIOMOSAIC films are self‐regenerated, portable, reusable, and freestanding. They are multifunctional depending on types of gene expressions from the cells, catalyzing various reactions such as l‐DOPA production, dephosphorylation, and lipid hydrolysis. Furthermore, BIOMOSAIC film exhibits effective crude oil degradation properties, indicating that it can be a new self‐producing and self‐sustaining platform for bioremediation.
