Article Synopsis
- Alcohol poses significant health risks, including mental health issues like depression and anxiety, highlighting the need for monitoring alcohol levels in biological samples to promote health.
- Researchers created a new electrochemical sensor for detecting ethanol in saliva, utilizing stabilized gold nanoparticles (Sp-AuNPs) to enhance sensitivity and performance.
- The sensor demonstrated a high detection accuracy (99.6% recovery rate) for ethanol in saliva, making it a promising tool for precise alcohol monitoring.
Nicotine is the one of the major addictive substances; the overdose of nicotine (NIC) consumption causes increasing heart rate, blood pressure, stroke, lung cancer, and respiratory illnesses. In this study, we have developed a precise and sensitive electrochemical sensor for nicotine detection in saliva samples. It was built on a glassy carbon electrode (GCE) modified with graphene (Gr), iron (III) phthalocyanine-4,4',4″,4'''-tetrasulfonic acid (Fe(III)Pc), and gold nanoparticles (AuNPs/Fe(III)Pc/Gr/GCE).

- High concentrations of nicotine are risky for adults, prompting the development of a sensor using a composite material (MXene/Pd(OH)/C) to detect nicotine levels in human sweat.
- The MXene/PHC composite-modified electrode displayed improved sensitivity and selectivity towards nicotine oxidation, achieving a detection limit of 27 nM.
- Testing in real human sweat samples from a smoker yielded a 97% recovery rate of nicotine, indicating the sensor’s effectiveness for accurate nicotine measurement.
