Gold-platinum nanowires are proposed as electrocatalysts for a real-time nonenzymatic impedancimetric detection of glucose. The electrochemical behavior the obtained platform toward electrocatalytic oxidation glucose, including proposal mechanism, is shown.
The rapidly emerging field of organic bioelectronics exploits the functional versatility conducting polymers to transduce biological recognition events into electronic signals. For majority biosensors or biomedical devices, immobilization a biorecognition element is critical step improve biotic/abiotic interface. In this work, simple strategy described construct large‐area all‐plastic poly(3,4‐ethylenedioxythiophene) (PEDOT) electrodes displaying carbohydrate biorecognizable motifs. First,...
The 1st International Online Conference on Bioengineering (IOCBE 2024) was held online from 16 to 18 October 2024. With a theme of in Generative AI World, the conference featured presentations distinguished scholars at nexus engineering and clinics, food, industry, innovations bioengineering education. organized around six topics related themes: Regenerative Tissue Engineering; Biomechanics Sports Medicine; Biomedical Biomaterials; Nano-Biotechnology; Biosignal Processing; Biochemical...
We present a glucose biosensor based on ZnO nanowire self-sustained films grown compacted graphite flakes by the vapor transport method. Nanowire/graphite were fragmented in water, filtered to form colloidal suspension, subsequently functionalized with oxidase and finally transferred metal electrode (Pt). The obtained devices evaluated using scanning electron microscopy, energy-dispersive x-ray spectroscopy, cyclic voltammetry chronoamperometry. electrochemical responses of determined buffer...
American tegumentary leishmaniasis (ATL) is an endemic neglected tropical disease (NTD), its conventional treatment toxic, slow, and invasive. Rapid diagnosis crucial for the clinical management of suspected patients, so development use low-cost, miniaturised portable devices could be key.
We measured impedance in a cell containing culture broth inoculated with E. coli, before and during bacterial growth. The electrode interface components (Ri, Xi) the medium component Rm were separated by making use of Warburg's model frequency dependent properties. Measurements carried out at different frequencies (from 18 Hz to kHz) constant current bridge as growth proceeded. It was found that: Growth curves for Ri Xi showed similar temporal pattern within range 18-100 Hz. Dispersion not...

A low-cost, portable microfluidic platform for preparing monodisperse magnetoliposomal suspensions that does not require extrusion steps.
A polymer piezoelectric micropump fabricated with conventional machining methods that can be embedded in laminated microfluidic chips.
Abstract A staple‐based electrochemical platform is proposed for the first time as a simple and low‐cost detection system paper‐based devices. The system, which incorporates small disposable stainless‐steel staples electrodes, combined with paper strip. staple acting working electrode modified carbon ink. was carefully optimized ferrocene carboxylic acid. As proof‐of‐concept, it employed enzymatic [horseradish peroxidase (HRP)‐based] immunoelectroanalytical of human tissue...
Honey and pollen from Tetragonisca fiebrigi Scaptotrigona jujuyensis, stingless bees northern Argentina, presented a particular microbiological profile associated enzymatic activities. The cultured bacteria were mostly Bacillus spp. (44%) Escherichia (31%). phylogenetic analysis showed taxonomic distribution according to the type of bee that was similar in both species. Microbial activities studied using hierarchical clustering. main bacterium responsible for enzyme production. Isolates with...
