上转换荧光技术在食品安全检测中的应用

Up-converting phosphor technology and its application in the field of food safety detection

上转换荧光技术是基于上转磷光体的新型检测技术,因其独特优越性,成为标记检测技术中新的研究热点。本文综述了上转换荧光技术的研究机制、国内外实际应用和发展状况等。发现该技术在大肠杆菌、布鲁氏菌、链球菌等食品安全检测中应用效果极佳,但当前技术仍有一定缺陷,亟需通过改进合成工艺、表面修饰等方法完善,进一步推进其在食品安全检测领域的应用。

The up-converting phosphor technology (UPT) based on up-converting phosphor (UCP) is a new kind of detection technology and because of its unique features it has become the topic of much new research in mark detection technology. This article mainly reviewed the mechanism, application and developmental situation of UPT. It was found that UPT had a favorable effect on Escherichia coli, brucella and streptococcus in the field of food safety detection, but the current technology still had some certain defects. Through the improvement of synthesis technology and surface modification methods, the UPT could be enhanced and its application in the field of food safety detection could be more useful.
