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。
Upconversion fluorescence technology is a new type of detection technology based on up-conversion phosphors. Due to its unique superiority, upconversion fluorescence has become a new research hotspot in the marker detection technology. This review summarizes the research mechanism of up-conversion fluorescence technology, its application and development at home and abroad. It has been found that this technique is very effective in the food safety testing of Escherichia coli, Brucella, Streptococcus, etc. However, the current technology still has some defects and it is urgently needed to improve it by means of improving the synthesis process and surface modification, Application of safety testing.
