通过溶剂提取紫甘蓝中的花青苷色素(CabAn),在该色素化学结构的基础上,利用其质子化互变异构形成pH响应变色的特点,设计其与羟胺盐组合为超分子探针,通过甲醛与羟胺盐反应释放质子,而该质子则与花青苷的青绿色醌式体结合转化为紫红色吡... 通过溶剂提取紫甘蓝中的花青苷色素(CabAn),在该色素化学结构的基础上,利用其质子化互变异构形成pH响应变色的特点,设计其与羟胺盐组合为超分子探针,通过甲醛与羟胺盐反应释放质子,而该质子则与花青苷的青绿色醌式体结合转化为紫红色吡喃鎓式,从而实现甲醛变色功能,并将超分子探针溶于琼脂制备成智能凝胶(CabAn_HA@Agar),按照国际照明委员会基于CIELab颜色空间定义色差的方法来测量计算甲醛浓度。 展开更多

What is already known about this topic?Acquired immunodeficiency syndrome(AIDS)represents a significant public health challenge globally,not only inflicting harm on the health of individuals but also placing a considerable economic strain on society.What is added by this report?This study represents the inaugural report on the potential reduction in economic burden attributable to human immunodeficiency virus(HIV)prevention strategies in Tianjin.Between 2011 and 2022,it is estimated that effective measures could prevent 2,965 new HIV infections and avert 658 deaths,resulting in an economic benefit of approximately 14.437 billion Chinese Yuan.What are the implications for public health practice?The findings of this study offer valuable evidence to inform the development of localized HIV prevention and control strategies,as well as to guide public health policymaking. 展开更多
