Fig. 2From: Ultrasensitive thrombin sensing platform based on three-way junction initiated dual signal amplificationAssembly of capture probe and feasibility of the sensing system. a Fluorescence intensities of the FAM labeled capture probe before and after assembly; b fluorescent spectrum of the approach when DNA polymerase, Nb.BbvCI, and ThT existed or not. Control refers to the result when thrombin was absent in the systemBack to article page
