The hormone abscisic acid (ABA) is crucial in the regulation of many physiological processes in plants, particularly in stress response and developmental control. Recent developments in detection methods utilizing opto-electronic sensors have enabled a more profound comprehension of the processes linked to plant hormones, namely ABA. The present work investigates the potential uses of opto-electronic sensors produced from tailored perovskite materials for the targeted detection of ABA. Modified perovskite substrates, which are characterized by their large surface area, intense Raman scattering, and great sensitivity, provide a distinct advantage in differentiating ABA from other interfering substances present in intricate plant media. Notwithstanding the advancements in these sophisticated detection methods, there is still a significant lack of knowledge on how the distinct opto-electronic characteristics of high-purity perovskite crystals impact their ability to detect ABA. This work aims to close this gap by a thorough investigation of the production, modification, and use of sensors based on perovskite materials. This study also intends to give a thorough analysis comparing the performance of perovskite substrates with traditional substrates, with a specific focus on important characteristics including efficiency, specificity, and sensitivity. Furthermore, the objective of this study is to evaluate the capacity of perovskite substrates to surpass the constraints of conventional detection techniques, namely in terms of sensitivity and interference from competing matrix components. The objective of this work is to make novel contributions to the design and optimization of opto-electronic sensors based on perovskite materials, with the goal of achieving more accurate and dependable detection of ABA. Consequently, this could facilitate the advancement of specialized diagnostic instruments for monitoring plant hormones, so enabling the use of enhanced agricultural techniques and effective stress management in plants.
脱落酸（ABA）激素在植物许多生理过程的调节中至关重要，尤其是在应激反应和发育控制方面。利用光电传感器的检测方法的最新进展，使人们能够更深入地理解与植物激素（即ABA）相关的过程。本研究探讨了由定制钙钛矿材料制成的光电传感器在靶向检测ABA方面的潜在用途。改性钙钛矿底物具有大表面积、强烈的拉曼散射和高灵敏度等特性，在区分ABA与复杂植物介质中存在的其他干扰物质方面具有明显优势。尽管这些先进检测方法取得了进展，但对于高纯度钙钛矿晶体独特的光电特性如何影响其检测ABA的能力，仍存在重大知识空白。这项工作旨在通过对基于钙钛矿材料的传感器的生产、改性和使用进行全面研究来填补这一空白。本研究还打算进行全面分析，比较钙钛矿底物与传统底物的性能，特别关注效率、特异性和灵敏度等重要特性。此外，本研究的目的是评估钙钛矿底物超越传统检测技术限制的能力，即在灵敏度和来自竞争基质成分的干扰方面。这项工作的目标是为基于钙钛矿材料的光电传感器的设计和优化做出新贡献，以实现对ABA更准确、可靠的检测。因此，这可以促进用于监测植物激素的专用诊断仪器的发展，从而实现更先进的农业技术和植物有效的应激管理。
