“…According to literature, ethanol sensors are commonly fabricated using materials such as graphene oxide [22,23], carbon nanotubes [10], and various metals including Fe [11], Ti [24], In [25], and mainly Zn [6,7,12,23,26]. Enzymatic methods are often used to measure ethanol concentration in human saliva, but they tend to reveal some instability under ambient conditions [17].…”

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.

“…Over the last few decades, the use of various active materials including semiconducting metal oxides and nitrides, polymers, ionic membranes, and salts has been extensively explored for chemoresistive gas sensing devices [9,10]. The most popular groups are the semiconducting metal oxides and nitrides, as they provide an array of advantages such as low-power-consumption, flexibility, as well as simple architecture [11][12][13][14]. However, their high operating temperatures (>250 • C) and extreme sensitivity to humidity [11][12][13]15] hinder their fundamental application as high-performance acetone and/or ethanol sensing devices.…”

However, their high operating temperatures (>250 • C) and extreme sensitivity to humidity [11][12][13]15] hinder their fundamental application as high-performance acetone and/or ethanol sensing devices. Recently, the successful development and implementation of graphene-based VOCs sensors brought growing attention towards other members of the layered twodimensional (2D) materials family, such as transition metal dichalcogenides (TMDs) and hexagonal boron nitride (hBN) nanosheets [13,[16][17][18][19][20].…”

The application of BaF2-modified hBN flakes as rapid response and recovery as well as sensitive chemoresistive sensing device materials for detection of acetone and/or ethanol is presented in this study. Modification of the hBN flakes was achieved by using the modified polymer derived ceramics (PDCs) process through the use of 0–10 wt% BaF2 and 5 wt% Li3N. Upon exposure to individual acetone and ethanol vapours, room temperature sensing studies revealed high LoD values (−144–460 ppmacetone and −134–543 ppmethanol) with extremely compromised sensitivities of −0.042–0.72 × 10−2 ppm−1acetone and −0.045–0.19 × 10−2 ppm−1ethanol for the structurally improved 5–10 wt% BaF2-modified hBN flakes. Moreover, enhanced sensing for 0–2.5 wt% BaF2-modified hBN flakes, as shown by the low LoDs (−43–86 ppmacetone and −30–62 ppmethanol) and the high sensitivities (−1.8–2.1 × 10−2 ppm−1acetone and −1.5–1.6 × 10−2 ppm−1ethanol), was attributed to the presence of defects subsequently providing an abundance of adsorption sites. Overall, the study demonstrated the importance of structural properties of hBN flakes on their surface chemistry towards room temperature selective and sensitive detection of VOCs.
