Detection of an ultralow concentration mRNA is important in the prognosis gene-related diseases. In this study, a DNA-conjugated amphiphilic aggregation-induced emission probe (TPE-R-DNA) was synthesized for cancer tissue imaging and analysis based on exonuclease III-aided target recycling technique. TPE-R-DNA comprise two components: hydrophobic component that serves as "turn-on" long wavelength fluorescence agent (TPE-R-N3); hydrophilic single DNA strand (Alk-DNA) which acts specific...
A plasmon resonance sensor (SPR) based on D-shape photonic crystal fiber (PCF) is proposed to realize the simultaneous measurement of refractive index (RI) and temperature.
