The development of tools to quickly identify the fate of damaged trees after a stress event such as a wildfire is of great importance. In this context, an innovative approach to assess irreversible physiological damage in trees could help to support the planning of management decisions for disturbed sites to restore biodiversity, protect the environment and understand the adaptations of ecosystem functionality. The vitality of trees can be estimated by several physiological indicators, such as cambium activity and the amount of starch and soluble sugars, while the accumulation of ethanol in the cambial cells and phloem is considered an alarm sign of cell death. However, their determination requires time-consuming laboratory protocols, making the approach impractical in the field. Biosensors hold considerable promise for substantially advancing this field. The general objective of this review is to define a system for quantifying the plant vitality in forest areas exposed to fire. This review describes recent electrochemical biosensors that can detect plant molecules, focusing on biosensors for glucose, fructose, and ethanol as indicators of tree vitality.
开发快速识别野火等应激事件后受损树木命运的工具非常重要。在这种情况下，评估树木不可逆生理损伤的创新方法可以帮助支持受干扰地点的管理决策规划，以恢复生物多样性、保护环境并了解生态系统功能的适应性。可以通过几种生理指标来估计树木的活力，例如形成层活动以及淀粉和可溶性糖的含量，而在形成层细胞和韧皮部中积累乙醇则被认为是细胞死亡的警报信号。然而，它们的测定需要耗时的实验室方案，因此在野外不切实际。生物传感器在极大地推进这一领域方面具有相当大的潜力。本综述的总体目标是定义一种用于量化暴露于火灾的森林区域中植物活力的系统。本综述描述了最近可以检测植物分子的电化学生物传感器，重点介绍了用于葡萄糖、果糖和乙醇的生物传感器，这些生物传感器是树木活力的指标。
