“…Electroactive biofilm formation is a cyclic process that occurs through five stages, including reversible attachment (initial contact stage I), irreversible attachment (cell adhesion stage II), biofilm maturation (biofilm growth stage III and stable maturation stage IV), and dispersion (stage V). 322 Although the engineering strategies discussed above are capable of enhancing biofilm formation at a single stage, it remains unknown whether the full-cycle of biofilm regulation is more conducive to biofilm formation. A recent study by Tang et al tried to address this issue by engineering the full-cycle biofilm formation processes.…”

“…Several outstanding reviews have brought attention to the crucial role of solar energy flow within biohybrid systems and have established a scientific foundation based on previous discoveries. Notably, Yang and Reisner et al, pioneers of the semiartificial photosynthesis concept, have underscored the significance of investigating the interaction of the semiconductor-cell interface. ,,,− Numerous noteworthy reviews on microbial electrochemistry have also delved into the transport of energy from the material (i.e., electrode) to the cell, followed by the subsequent conversion from electrical to chemical energy. − However, a systematic analysis and comprehensive review of this intricate and transient energy flow process are still lacking. Indeed, the energy flow mechanism in NMHS remains akin to a “ Black Box ” as illustrated in Figure , though its inputs (e.g., incident light and chemical substrates) and outputs (e.g., chemical products and quantum yields) can be easily monitored and analyzed, the relationship between the two and its internal workings, i.e., the mechanisms underlying the characters and functionalities of NMHS, remain predominantly unclear and challenging to delineate.…”

Nanomaterial-microorganism hybrid systems (NMHSs), integrating semiconductor nanomaterials with microorganisms, present a promising platform for broadband solar energy harvesting, high-efficiency carbon reduction, and sustainable chemical production. While studies underscore its potential in diverse solar-to-chemical energy conversions, prevailing NMHSs grapple with suboptimal energy conversion efficiency. Such limitations stem predominantly from an insufficient systematic exploration of the mechanisms dictating solar energy flow. This review provides a systematic overview of the notable advancements in this nascent field, with a particular focus on the discussion of three pivotal steps of energy flow: solar energy capture, cross-membrane energy transport, and energy conversion into chemicals. While key challenges faced in each stage are independently identified and discussed, viable solutions are correspondingly postulated. In view of the interplay of the three steps in affecting the overall efficiency of solar-to-chemical energy conversion, subsequent discussions thus take an integrative and systematic viewpoint to comprehend, analyze and improve the solar energy flow in the current NMHSs of different configurations, and highlighting the contemporary techniques that can be employed to investigate various aspects of energy flow within NMHSs. Finally, a concluding section summarizes opportunities for future research, providing a roadmap for the continued development and optimization of NMHSs.

“…Biofilm growth can also improve EET between microorganisms and electrodes. Optimizing growth conditions, surface modification, and biofilm engineering approaches are methods to improve the formation of biofilm [11,12]. Another method of improving EET is to optimize the material of the electrode.…”

Extracellular electron transfer (EET) is a biological mechanism that plays a crucial role in various bioelectrochemical systems (BESs) and has substantial implications for renewable energy production. By utilizing the metabolic capacities of exoelectrogens, BESs offer a viable and environmentally friendly approach to electricity generation and chemical production; however, the diminished effectiveness of EET remains a hindrance to their optimal application in practical contexts. This paper examines the various strategies that have the potential to be employed to enhance the efficiency of EET systems and explores the potential for the integration of BESs technology with contemporary technologies, resulting in the development of an enhanced and sustainable system. It also examines how quorum sensing, electrode modifications, electron shuttles, and mediators can aid in improving EET performance. Many technological innovations, such as additive manufacturing, the science of nanotechnology, the technique of genetic engineering, computational intelligence, and other combinations of technologies that can be used to augment the efficacy of BESs are also discussed. Our findings will help readers understand how BESs, though an evolving technology, can play an important role in addressing our environmental concerns. Technical constraints are identified, and future directions in the field of EET are suggested.
