摘要

The actin depolymerizing factor (ADF)/cofilin protein family has been reported to be associated with ischemia induced renal disorders. Here we examine if cofilin-1 is associated with acute kidney injury (AKI). We exploited a 96-well based fiber-optic biosensor that uses conjugated gold nanoparticles and a sandwich immunoassay to detect the urine cofilin-1 level of AKI patients. The mean urine cofilin-1 level of the AKI patients was two-fold higher than that of healthy adults. The receiver operating characteristic (ROC) curve showed that cofilin-1 is a potential biomarker for discriminating AKI patients from healthy adults for intensive care patients.
