Abstract:
The inflammatory microenvironment involves changes in pH and protein phosphorylation state and is closely related to the occurrence and development of atherosclerosis (AS). Herein, we constructed a dual‐detection fluorescence nanosensor PCN‐NP‐HPZ based on post modification of MOFs, which realized the simultaneous detection and imaging of pH and phosphorylation through the pH‐sensitive group piperazine and the Zr IV node of the MOFs. The sensors were used to monitor changes in blood pH and phosphate levels at different time stages during atherosclerotic plaque formation. Two‐photon fluorescence imaging was also performed in the vascular endothelium. Blood tests combined with two‐photon fluorescence images indicated that in the early stage of AS, blood and tissue pH levels were lower than that of the normal mice, while phosphate and tissue phosphorylation levels were higher than that of the normal mice. The present study provides a new analysis method for the assessment of early atherosclerotic disease.
