摘要	An ultrasensitive dual optical method for measuring antioxidant concentration and total antioxidant capacity is provided. Using the process, the detection limit for vitamin C is as low as 7 nM. The method is based on a hybrid of single walled carbon nanotubes (SWNT) with hydrogen-peroxide. The method provides is a robust, cheap, fast, and reusable optical sensing method for antioxidant and total antioxidant capacity measurement in foods and plasma. The method can also be developed as a miniature assay for both in vitro and in vivo detection.
其他摘要	提供了一种用于测量抗氧化剂浓度和总抗氧化能力的超灵敏双光学方法。使用该过程，维生素C的检测限低至7 nM。该方法基于单壁碳纳米管（SWNT）与过氧化氢的混合物。该方法提供了一种稳健，廉价，快速且可重复使用的光学传感方法，用于食品和血浆中的抗氧化剂和总抗氧化剂容量测量。该方法还可以开发为用于体外和体内检测的微型测定法。
