Here we present a molecularly imprinted polymer (MIP)-based electrochemical sensor using a laser-induced graphene (LIG) electrode modified with poly(3,4-ethylenedioxythiophene) (PEDOT) for selective and sensitive lactate detection.

The flexible sensor maintained stable performance under mechanical stress and exhibited good operational stability. Using square wave voltammetry, the LIG-MIP biosensor demonstrated a wide detection range of 0.1–1000 μM with a high sensitivity of 27.68 μA/log μM, and a low detection limit of 0.033 μM. Selectivity toward lactate was confirmed in the presence of potent interferents in lactate analysis. The stability and reproducibility were evaluated and validated in artificial saliva.

Indeed, microbial electrosynthesis has already been proved as a suitable strategy for polyhydroxybutyrate production under photoautotrophic conditions. In contrast with classical biofilm-based electromicrobiology studies, fluid-like electrodes can tune planktonic microbial metabolism to enhance biodegradation rates in brewery wastewater. In this work we have explored polyhydroxybutyrate production in a mixed community enriched from brewery wastewater using a photo-microbial electrochemical moving bed reactor (photoME-MBR). The bioelectrochemical reactor was operated under cathodic conditions (−0.8 V vs Ag/AgCl) with acetate as carbon source as a mean to evaluate i) PHB production and ii) bioelectrochemical performance. We observed how a cathodic polarization of the moving electrode played a key role on PHB production stimulating both direct microbial electron uptake from the conductive bed and electrochemically produced hydrogen in the vicinity of the current collector. Overall, the polarized reactor outperformed the non-polarized reactor by four-fold regarding PHB production rate. In addition, microbial communities analysis revealed <em>Rhodopseudomonas</em> sp. and <em>Bradyrhizobium</em> sp. as main genera in combination with other electroactive genera like <em>Geosporobacter</em> sp.

We studied how the packet repetition rate, pulse width, and packet number influence remote focusing of electroporation and its suppression near electrodes. Cell monolayers were electroporated by packets of 300-, 600-, or 900-ns pulses from four needle electrodes arranged in a square with 15.3-mm diagonals. Electroporative dye uptake peaked at the center of the square and decreased laterally following Lorentzian distribution. Higher packet rates, longer pulses, and a smaller number of packets sharpened the central peak, reducing its full width at half maximum (FWHM) to 1.1 mm, which was 7.3 % of the diagonal and just 2.3 % of the electrode array area. At 0.2 MHz, electroporation near electrodes was 40-fold weaker than at the center, despite a 4-fold stronger electric field.

Unlike most conventional multi-target methods requiring complex probe labeling and prone to signal cross-talk, a novel multifunctional sensor incorporating host-guest chemistry in electrochemical assays was developed to detect protein, nucleic acid, and small molecule with a single electrode in this work. This sensor operates in three distinct modes: protein detection, nucleic acid detection, and small molecule detection. In the protein detection mode, the methylene blue (MB)-labeled probe recognized the thrombin and formed a probe/thrombin complex, inducing fewer probes to be captured by the <em>β-</em>cyclodextrin (<em>β</em>-CD) and enabling a measurable electrochemical signal change. In the nucleic acid detection mode, the <em>p53</em> gene interacted with the corresponding probe and formed a rigid double-stranded DNA (dsDNA) structure, reducing the electron transfer rate constant (<em>k</em><sub>s</sub>) and inhibiting MB signal transmission. In the small molecule detection mode, cholesterol competitively bonded with the host molecules and removed MB from the <em>β</em>-CD cavity, leading to an electrochemical signal decrease. Under optimized detection conditions, this sensor displayed an effective analytical performance for thrombin, <em>p53</em> gene, and cholesterol, achieving low detection limits of 61.7 pM, 7.3 nM, and 14.3 μM, respectively. Importantly, this platform enables rapid regeneration in the nucleic acid detection mode and reliable operation in complex samples, outperforming previous multi-target detecting methods in reusability, anti-interference capacity, and ease of construction.
