The combination of two-dimensional materials and metal nanoparticles (MNPs) allows the fabrication novel nanocomposites with unique physical/chemical properties exploitable in high-performance smart devices biosensing strategies. Current methods to obtain graphene-based films decorated noble MNPs are cumbersome, poorly reproducible, difficult scale up. Herein, we propose a straightforward, versatile, surfactant-free, single-step technique produce reduced graphene oxide (rGO) conductive...
Graphene-based materials are of interest in electrochemical biosensing due to their unique properties, such as high surface areas, and biocompatibility. However, the scalable production graphene electrodes remains a challenge; it is typically slow, expensive, inefficient. Herein, we reported simple, fast, maskless method for large-scale, low-cost reduced oxide electrode fabrication; using direct writing (laser scribing inkjet printing) coupled with stamp-transferring method. In this process,...
An electroanalytical lab-on-a-strip device for the direct extra-virgin olive oil (EVOO) antioxidant capacity evaluation is proposed. The lab-made composed of a CO2 laser nanodecorated sensor combined with cutter-plotter molded paper-strip designed EVOOs sampling and extraction. Satisfactory performance towards most representative o-diphenols i.e., hydroxytyrosol (HY) oleuropein (OL) were achieved; good sensitivity (LODHY = 2 µM; LODOL 0.6 µM), extended linear ranges (HY: 10-250 OL: 2.5-50...
In this work, a rapid and simple gold nanoparticle (AuNPs)-based colorimetric assay meets new type of synthesis AuNPs in organic medium requiring no sample extraction. The extraction-free approach strategically involves the use dimethyl sulfoxide (DMSO) acting as an solvent for simultaneous analyte solubilization stabilization. Moreover, DMSO works cryogenic protector avoiding solidification at temperatures used to block synthesis. addition, chemical function stabilizers endogenous fatty...
In this work, a nanostructured conductive film possessing nanozyme features was straightforwardly produced via laser-assembling and integrated into complete nitrocellulose sensors; the cellulosic substrate allows to host live cells, while activity ensures enzyme-free real-time detection of hydrogen peroxide (H
In this work a peptide based gas sensor array of ZnO nanoparticles (ZnONPs) has been realized. Four different pentapeptides molecularly modelled for alcohols and esters having cysteine as common spacer have immobilized onto ZnONPs. ZnONPs morphologically spectroscopically characterized. Modified then deposited quartz crystal microbalances (QCMs) used sensors with nitrogen carrier gas. Analysis the pure compounds demonstrated nice fitting modelling real data. The had very low sensitivity to...
Monitoring synthetic colorants in foods is important due to their potential toxicity and pathogenicity. We propose here a new simple method for the extraction determination of erythrosine B (ERT-B) food samples. A composite polydopamine-based molecularly imprinted polymers coating magnetic nanoparticles (Fe3O4@PDA@MIP) was synthesized using green approach exploited dispersive solid-phase (MDSPE) ERT-B. Fe3O4@PDA@MIP provides rapid ERT-B, exhibiting good reusability preconcentration ability....
A novel breathable electrochemical enzyme-free sensor made from laser-induced carbon nanofibers embedding Ni nanocatalysts (Ni-LCNFs) is proposed for the capture and detection of biomarkers in breath aerosol. The permeable Ni-LCNF electrodes were fabricated on filter paper where a hydrophobic wax barrier was created to confine device's working area. device tested with aerosolized glucose, which collected porous electrode. After subsequent drying step, 0.1 M NaOH dropped onto device,...
Abstract The effect of the oxidation degree multiwalled carbon nanotubes (MWCNTs) for detection NADH was evaluated in this paper. MWCNTs were oxidized by microwave‐assisted sulfonitic treatment at different times (5, 10, 15, and 30 min) deposited onto a graphite screen printed electrodes. Oxidized characterized electrochemical performance evaluated. best sensor terms sensitivity stability obtained after 15 minutes (SPE/CNT15). A significant reduction potential recorded compared with...
