New Handheld Strip Analyzer for On-Site Rapid Detection of Paralytic Shellfish Poisoning Based on a Smartphone
摘要
Abstract
Saxitoxin( STX) are common marine toxins which can affect human health through food chain by accumu-lating in shellfishes. It is urgently required to have a convenient method for on-site detection of marine toxins to a-void the poisoning incidents that have occurred frequently. In this work,a handheld analysis meter system coopera-ting with competitive immunoassay strips is designed for rapid detection of STX. The smartphone is used as light de-tector,for image acquisition and data processing by a specific application. The 3D-printed portable accessory of sm-artphone is fixed for test strip. The method is simple and fast,with a detection limit of STX of 5.2 ng/mL,respec-tively. It can provide quantitative analysis of STX in the range of 5.2 ng/mL~100 ng/mL. Based on the smartphone system and biochemical analysis,it will be promising tool for on-site rapid detection for paralytic shellfish poisoning.关键词
