“…However, the detection of hydrazine at DCD-modified SPCE* exhibited an increased current response with a lower overpotential of ∼0.3 V (curve D). As observed, hydrazine is easily involved in the hydrogen-bonding formation (NH···N), onto the DCD-SPCE* surface, − and consequently then triggering the onset potential for sensitive detection of hydrazine through the ECE mechanism. − …”

A new technique for sensing nanomolar concentrations of hydrazine in water samples is reported. A screen-printed carbon electrode (SPCE) altered using an amine-azo functional group encompassing poly(dicyandiamide) is used in this study. The modified electrode exhibits an enhanced activity toward hydrazine detection at a lower overpotential and broad linear scale between 20 nM and 1 mM, with an accurate sensitivity value of 0.1 nA μm–1 cm–2. To the best of our knowledge, poly(dicyandiamide)-modified electrodes exhibit one of the lowest limits of detection for any metal-free electrode that detects 6.7 nM (S/N = 3) of hydrazine. The method established sufficient selectivity and better recoveries. Finally, the poly(dicyandiamide)-modified SPCE* is highly suitable for electrochemical determination of hydrazine in water samples from tap and lake.

“…Clenbuterol (CLB), as a member of β 2 adrenergic agonists, can decrease fat accumulation, promote lipolysis, improve protein synthesis, and significantly increase the leanness of carcasses. , It was once widely used as a growth promoter and feed additive in the livestock industry. , At present, CLB has been banned for use as a growth promoter in livestock in many countries because it can accumulate in the body through the food chain and cause various health problems including fatigue, dizziness, palpitation, metabolic disorders, and muscular tremors. − Unfortunately, there are still many cases of illegal use of CLB as a feed additive in feeding farm animals. Therefore, sensitive and specific detection of CLB residues in sold meat products is of great significance for ensuring food safety and human health.…”

In view of the potential harm caused by illegal feeding of clenbuterol (CLB) in the livestock industry, herein, a novel ratiometric fluorescent probe based on graphene quantum dots (GQDs)@[Ru(bpy) 3 ] 2+ was elaborately constructed for CLB detection. In this probe, GQDs acted as response signals, and their fluorescence was remarkably quenched by CLB through the diazotization-coupling reaction. As for [Ru(bpy) 3 ] 2+ as a reference signal, its fluorescence was hardly affected. The intensity ratio of two fluorophores showed good linearity with CLB concentration in the range of 0.05−40 μM, accompanied by visualization of fluorescence variation from yellow to red. The detection limit was as low as 0.029 μM. Particularly, the probe was successfully used to detect CLB in pork and beef samples with satisfactory recoveries. To our knowledge, this is the first report on a ratiometric fluorescent probe for the detection of CLB, which possesses broad application prospects in food safety risk monitoring.
