Herein, we depict that the consequential nickel/nickel oxidereduced graphene oxide (Ni/NiO-rGO) hybrid materials synthesized by sol-gel approach can give as competent electrocatalyst for oxidative determination of ethanol in alkaline condition. Ni/ NiO-rGO based electrochemical sensor shows rapid and highly sensitive linear sweep voltametric (LSV) response to ethanol at an ultra-low oxidation potential of 0.33 V vs. SCE. Moreover, the electrochemical sensor demonstrates highly stable (current and potential) also with low charge transfer resistance confirmed from chronoamperometic (i-t) and electrochemical impedance spectroscopic (EIS) data respectively towards ethanol oxidation at Ni/NiO-rGO hybrid interface confirms its acitivity over individuals i. e. Ni/NiO nanoparticles and rGO. Moreover, linear increase in current density upto 100 μM concentration of ethanol and for the scan rates in the range of 10-100 mV/s with positive shift in potential confirms ethanol oxidation is diffusion controlled process.

“…An example of such a sensor is the ethanol sensor, which finds applications in industrial processes to monitor chemical reactions, in biomedical instruments for evaluating food and beverage quality, and for the detection of bacteria and fungi [6][7][8][9][10]. While many sensors are designed to analyze ethanol gas [6,7,10,11]; there is also a need for sensors capable of detecting ethanol dissolved in aqueous media, particularly for assessing in situ ethanol concentrations in drinks, fuel, water, blood, urine or saliva samples [12,13].…”

In this work, we report a non‐enzymatic and metal‐free ethanol sensor based on 3D PLA‐graphene electrodes. We evaluated the optimal activation treatment for PLA‐graphene to achieve a sensor for monitoring ethanol levels in saliva samples, following the legal limits for drivers in various countries. The analytical performance of the sensor was determined through amperometric measurements, demonstrating a linear detection ranging supporting electrolyte (0.990−19.3 mmol L ‐1) and artificial saliva sample (0.990−17.4 mmol L ‐1), with respective limits of detection of 0.135 and 0.239 mmol L ‐1. The 3D‐printed sensor exhibited excellent repeatability and reproducibility. This method was effectively employed for ethanol detection, highlighting its potential as an alternative approach for assessing ethanol levels in drivers while considering diverse legal regulations across different countries.

The devices with non-invasive characteristics have aroused people’s wide concern based on sweat analysis, such as providing real-time and accurate test of ethanol concentration. Unfortunately, these devices show limited selectivity, sensitivity, and stability owing to the existing planar electrodes with sluggish mass transport and inefficient active site utilization. The Au NW-gel bioelectrode exhibited good and quick linear current responses toward a broad range of ethanol concentration from 0.01 to 0.5 M. It was validated to an appreciable stability and selectivity to ethanol detection in the existences of sodium chloride, lactic acid, and urea. The abnormal concentration of ethanol in human’s biofluids is the index of unhealthy conditions from internal diseases. Herein, we introduce the application of gold nanowire aerogel (Au NW-gel) in detecting the concentration of ethanol in simulated human sweat. A preparation method based on substrate-assisted growth method is introduced. The length of Au NW synthesized by the substrate-assisted growth method is 10–20 μm. Au NW-gel has an ultralow density and high gold content, which can reduce the internal resistance of the electrode sufficiently. The pore structure of aerogel can accelerate the mass transfer process and make the Au NW-gel have excellent performance. The linear relationship between peak current and ethanol concentration in simulated sweat is established, and the retention capability of the biosensor is more than 83%. Furthermore, a simulation model is developed to validate the robust mass transfer and electrochemical performance of the porous electrode. The Au NW-gel-based electrode provides an effective pathway for detecting the ethanol content in sweat precisely.
