信号放大技术在食品安全检测领域的应用

Application of Signal Amplification Technology in the Area of Food Safety Detection

食品安全是保障人类健康、提高人类生活品质的基础,同时因我国当前所处经济社会发展的阶段性,食品安全问题在中国日益凸显。目前,食品安全检测领域主要面临检测方法不多、快检技术不成熟,尤其是缺乏超痕量的检测分析技术导致的检测灵敏度不高等问题。信号放大技术为这些问题提供了可能的解决途径,将信号放大技术与传统检测方法相结合,实现食品中重金属、生物/化学毒素、微生物及违法添加剂等方面的痕量检测正逐渐引起人们的重视。本文从四种主要的信号放大技术与该技术在食品安全检测中的研究现状、发展趋势两方面进行了概述,并展望了信号放大技术在食品安全检测领域的研究重点和未来的发展前景。

Food safety is the foundation of safeguarding human health and improving the quality of human life.At the same time,because of the phased development of our economy and society,food safety issues are increasingly exposed in China. At present,there are many problems in the area of food safety detection,including few detection methods, immature rapid detection methods, especially the absence of ultratrace analytical techniques leading to low detection sensitivity. Signal amplification technology provides a possible w ay to solve those problems. The combination of signal amplification technology and traditional detection methods is gradually attracting more attention because of its applications in the trace detection of heavy metal,biotoxin/chemical toxins,microorganism and illegal additives in foodstuffs. This review introduces four kinds of signalamplification technology and the applications and development tendency in the area of food safety detection. The emphasis and prospect of the development of signal amplification technology in this area are put forw ard.
