“…As we all know, hydrogen peroxide (H 2 O 2 ) is a small molecule with oxidation and reduction properties. [1][2][3][4] It can be used as disinfectant and also used in environmental protection, food industry, [5,6] fuel cells and clinical diagnosis. The concentration of H 2 O 2 in vivo is an important biological parameter for monitoring and maintaining physiological balance.…”

A new type of enzyme-free electrochemical sensor with BÀ Ag nanomaterials as electrocatalyst was designed. The obtained nanomaterials were characterized by transmission electron microscopy (TEM), energy dispersive spectroscopy (EDS) and powder X-ray diffraction (XRD). The results show that B was successfully doped onto the surface of Ag, which reduces the particle size of Ag nanoparticles and expands the crystal plane spacing of Ag, therefore making Ag display larger specific surface area and faster electron transfer rate. The new enzymefree electrochemical sensor based on BÀ Ag shows high electrocatalytic activity for the H 2 O 2 reduction and exhibits excellent sensing performance for the electrochemical detection of H 2 O 2 with a wide range from 0.01 mM to 5.55 mM, a high sensitivity of 68.3 μA⋅mM À 1 cm À 2 and a low detection limit of 0.04 μM. This study demonstrated BÀ Ag is a promising sensing material for electrochemical enzyme-free sensors.

“…The ability to qualitatively and quantitatively detect the presence of chemicals is one of the foundations of modern society. Chemical sensing and detection methods have found countless applications, with monitoring of technological processes [ 1 , 2 ], controlling product quality [ 3 ], monitoring the environment [ 4 ], diagnostics and health management [ 5 ], as well as constituting an element of early warning systems [ 6 ] being the most significant fields of their use. Although numerous parameters are used to describe the performance of the multitude of existing detection methods, the key parameter for most applications is the limit of detection (LoD), as it describes the lowest concentration of the intended analyte that can be observed via the selected detection method.…”

The detection of chemicals is a fundamental issue of modern civilisation, however existing methods do not always achieve the desired sensitivity. Preconcentrators, which are devices that allow increasing the concentration of the intended analyte via e.g., adsorption/desorption, are one of the solutions for increasing the sensitivity of chemical detection. The increased detection sensitivity granted by preconcentration can be used to miniaturise detection instruments, granting them portability. The primary goal of this review is to report on and briefly explain the most relevant recent developments related to the design and applications of preconcentrators. The key design elements of preconcentrators and the emerging area of liquid-phase preconcentrators are briefly discussed, with the most significant applications of these devices being highlighted.

“…Microbial electrochemical technologies (MET) promise great innovation in different fields, such as environmental pollution remediation, low power generation, biosensing, synthesis of new products and medicine. [1][2][3][4][5][6][7][8][9][10][11][12] However, the transfer from laboratory experimentation to field application is still challenging. Mostly, but not exhaustively, these technologies take advantage of a synergistic combination of well-known electrochemical and microbiological processes, needed to be mastered requires expertise of rarely a common background.…”

In memory of Dr. Alessandra ColomboA cross-laboratory study on microbial fuel cells (MFC) which involved different institutions around the world is presented. The study aims to assess the development of autochthone microbial pools enriched from domestic wastewater, cultivated in identical single-chamber MFCs, operated in the same way, thereby approaching the idea of developing common standards for MFCs. The MFCs are inoculated with domestic wastewater in different geographic locations. The acclimation stage and, consequently, the startup time are longer or shorter depending on the inoculum, but all MFCs reach similar maximum power outputs (55 � 22 μW cm À 2 ) and COD removal efficiencies (87 � 9 %), despite the diversity of the bacterial communities. It is inferred that the MFC performance starts when the syntrophic interaction of fermentative and electrogenic bacteria stabilizes under anaerobic conditions at the anode. The generated power is mostly limited by electrolytic conductivity, electrode overpotentials, and an unbalanced external resistance. The enriched microbial consortia, although composed of different bacterial groups, share similar functions both on the anode and the cathode of the different MFCs, resulting in similar electrochemical output.
