Abstract

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.
