Electrochemical biosensors and biofuel cells are finding an ever-increasing practical application due to several advantages. Biosensors are miniature measuring devices, which can be used for on-the-spot analyses, with small assay times and sample volumes. Biofuel cells have dual benefits of environmental cleanup and electric energy generation. Application of nanomaterials in biosensor and biofuel-cell devices increases their functioning efficiency and expands spheres of use. This review discusses the potential of nanomaterials in improving the basic parameters of bioelectrochemical systems, including the sensitivity increase, detection lower-limit decrease, detection-range change, lifetime increase, substrate-specificity control. In most cases, the consideration of the role of nanomaterials links a certain type of nanomaterial with its effect on the bioelectrochemical device upon the whole. The review aims at assessing the effects of nanomaterials on particular analytical parameters of a biosensor/biofuel-cell bioelectrochemical device.

The 3D bioprinting of aquatic photosynthetic organisms holds potential for applications in biosensing, wastewater treatment, and biofuel production. While algae cells can be immobilized in bioprinted cell-friendly matrices, there is a knowledge gap regarding the thresholds of hydrodynamic shear stress that affect the cells' functionality and viability during bioprinting. This study examines the effect of hydrodynamic shear stress on the fate of cells.

Microbial fuel cells (MFCs) are one of the contributors to the novel sustainable energy generation from organic waste. However, the application of MFCs is limited due to the slow charge transfer between cells and electrodes. This problem can be solved by modifying cells with conductive polymers, such as polypyrrole (PPy).

Recent studies on bioelectrochemical system (BES) denitrification focus predominantly on removal efficiency and electrode materials, yet a comprehensive understanding of electron transfer mechanisms and process coupling remains lacking. This research critically reviews the key microbial populations, Shewanella and Geobacter, and their dynamic electron transfer pathways. It reveals how electrodes, electron shuttles, and microbial communities establish three-dimensional extracellular electron transfer (EET) networks via cytochromes, nanowires and redox shuttle molecular.

There is an urgent need to investigate the distinct performance and mechanism of traditional constructed wetland (CW), microbial fuel cells-constructed wetland (MFC-CW) and direct-enchanced constructed wetland (ECCW) for antibiotics removal. To address this issues, three kinds of CWs were bulit and distinct performance and mechanism for levofloxacin (LVFX) removal was expored in this study. MFCCW, ECCW achieved high LVFX removal efficiencies compared with traditional constructed wetland (96.
