摘要
时钟反应是一种独特的非线性化学现象,其特点是体系在经历一段可控的、近乎恒定的“诱导期”后,某一物理化学性质(如颜色、pH值或电势)会发生急剧且突然的变化。基于这一特性,时钟反应已被开发成为一种高灵敏度、高选择性且简便快捷的分析工具。它将难以直接测量的浓度信息转化为易于精确测量的时间信号,兼具高灵敏度、强抗干扰性和操作简便的优点。未来的研究将致力于开发新的反应体系以拓展检测范围,提高在复杂实际样品中的选择性,并与微流控芯片、智能手机传感平台等技术结合,推动其在环境监测、食品安全和生物医学诊断等领域的实际应用。
A clock reaction is a unique nonlinear chemical phenomenon characterized by a controllable and nearly constant"induction period",after which a specific physicochemical property(such as color,pH,or electrical potential)undergoes an abrupt and sudden change.Leveraging this characteristic,clock reactions have been developed into highly sensitive,selective,and rapid analytical tools.They transform difficult-to-measure concentration information into easily and precisely quantifiable time signals,offering advantages such as high sensitivity,strong anti-interference capability,and operational simplicity.Future research will focus on developing new reaction systems to broaden detection scopes,improving selectivity in complex real-world samples,and integrating with technologies like microfluidic chips and smartphone-based sensing platforms.These efforts aim to promote their practical applications in fields such as environmental monitoring,food safety,and biomedical diagnostics.
