Special Issue Information

Dear Colleagues,

Pollutant monitoring plays a pivotal role in addressing pressing global environmental challenges, including soil degradation, water pollution, and air contamination. Recent breakthroughs in optical sensors, electrochemical sensors, micro/nanosensors, wearable devices, MEMS/NEMS, and biosensors have significantly enhanced the precision and efficiency of environmental parameter detection, opening new avenues for advanced pollution control.

To advance knowledge in this critical field, we are pleased to announce a Special Issue entitled “Micro/Nano-Biosensors for Environmental Applications”. This Special Issue aims to establish a high-impact interdisciplinary platform for discussions of the latest advances, key challenges, and future trends in micro- and nanosensing technologies for environmental monitoring. By compiling cutting-edge research from leading experts worldwide, this collection will foster in-depth discussions and knowledge exchange among researchers and industry professionals.

We warmly invite submissions of original research articles, comprehensive reviews, and case studies, covering (but not limited to) the following topics: MEMS-based sensing systems, nanomaterial-enhanced sensors, and emerging sensing technologies for pollutant monitoring. Your contributions will not only enrich the scientific discourse but also provide valuable insights to the global research community, driving innovation in pollution detection and mitigation technologies.

This study presents a low-cost, small-scale single-chamber microbial fuel cell (MFC) toxicity biosensor fabricated on a printed circuit board (PCB) and a 3D-printed chamber with a volume of 120 μL. The anode consists of a screen-printed carbon electrode on the PCB, while the air cathode is a carbon paper electrode. To address poor adhesion of microorganisms to the smooth anode surface, femtosecond laser processing was used to fabricate a micropore array with 40 μm pores on the electrode. This method can create micropores on the anode surface without damaging the screen-printed electrodes, the PCB substrate, or the pads. These micropores increase the anode’s surface area and hydrophilicity, allowing more microbial coatings to firmly adhere to its surface. In this study, the MFC utilised Rhizobium rosettiformans W3, extracted from activated sludge at a wastewater treatment plant, as the anode microorganism. Its aerobic nature simplifies the design of MFCs, enabling a single-chamber structure and miniaturisation. Using formaldehyde solution as a toxicity sample to test the biosensor’s performance, a 0.1% concentration significantly reduced the sensor’s output power. Full article
