Ratiometric fluorescent nanoprobe based on CdTe/SiO2/folic acid/silver nanoparticles core-shell-satellite assembly for determination of 6-mercaptopurine

Hollow structure molecularly imprinted ratiometric fluorescence sensor for the selective and sensitive detection of dopamine

“…Recently, ratiometric fluorescence sensors have become particularly attractive due to their excellent characteristics, which could overcome the problems of a single-emission fluorescence sensor. [9][10][11] A ratiometric fluorescence sensor could avoid interference from some factors and eliminate error by using the ratio of two fluorescence peaks. Thus, a ratiometric fluorescence sensor has better potential for quick detection by eye or smartphone due to its obvious difference in terms of color change.…”
