Photoelectrochemical (PEC) sensors have demonstrated significant potential in agricultural detection due to their high sensitivity, rapid response, and low cost. While significant research efforts have been dedicated to optimizing photoelectrode architectures and designing efficient photoactive materials for agricultural detection, there remains a lack of systematic discussion on the mechanistic interplay between light–energy conversion and target recognition in photoelectrochemical (PEC) sensors. This review comprehensively summarizes recent advances in PEC agricultural sensors, focusing on three core design rationales: (1) enhancing light absorption (doping, nanostructures), (2) optimizing charge transport (surface plasmon resonance effect, quantum dot sensitization, 2D materials/metal–organic frameworks (MOFs)), and (3) developing specific recognition elements. PEC sensors achieve target detection by converting light energy into electrical signals through photoelectrodes and integrating specific recognition elements (e.g., enzymes, antibodies, aptamers, or molecularly imprinted polymers). Furthermore, the article summarizes typical application scenarios of PEC sensors in agricultural detection (e.g., soil component analysis, pesticide residue detection, and antibiotic and mycotoxin monitoring) and provides insights into future developments. These advancements offer crucial theoretical references and technical support for precision monitoring in smart agriculture.

The use of Azospirillum brasilense has been widely disseminated as a strategy to increase agricultural productivity, but its use in conjunction with other products is still not well studied. A promising compound for this purpose is nicotinamide, which positively influences the morphophysiological characteristics of plants and may result in biostimulant effects, in addition to enhancing the characteristics of inoculation with the bacteria. This study aimed to evaluate the effect of the foliar application of Azospirillum brasilense and nicotinamide as biostimulants on corn plants. The treatments consisted of T1: control, T2: foliar application of nicotinamide (200 mg L–), T3: foliar application of Azospirillum brasilense (2 mL L–), and T4: combined application of nicotinamide and A. brasilense. Gas exchange characteristics, vegetative growth, mass accumulation, and distribution were evaluated. It was found that applying these compounds increased the gas exchange capacity of the plants and improved growth and the accumulation of dry mass, mainly related to the root. There was also a correlation between root development and gas exchange capacity. The application of nicotinamide provides gains related to root development, positively impacting gas exchange characteristics. In addition, its combined use with Azospirillum brasilense results in a synergistic effect, producing more compact plants and increasing stem thickness and efficiency in terms of gas exchange.
利用巴西氮螺旋菌作为一种提高农业生产力的策略已广泛传播，但其与其他产品的结合使用仍未得到很好的研究。烟酰胺是一种很有前景的化合物，它对植物的形态生理特性有积极的影响，除了增强细菌接种特性外，还可能产生生物刺激作用。本研究旨在评价玉米叶片施用氮螺旋菌和烟酰胺作为生物刺激素的效果。处理为T1：对照，T2：烟酰胺叶面施用（200 mg L -）， T3：巴西氮螺旋菌叶面施用（2 mL L -）， T4：烟酰胺与巴西螺旋菌联合施用。评估了气体交换特征、营养生长、质量积累和分布。结果表明，施用这些化合物增加了植物的气体交换能力，促进了植物的生长和干物质的积累，主要与根系有关。根系发育与气体交换能力之间也存在相关性。烟酰胺的应用提供了与根系发育相关的增益，积极影响气体交换特性。此外，它与巴西氮螺旋菌结合使用，产生协同效应，产生更致密的植株，增加茎粗和气体交换效率。
