Target-controlled gating liposome “off–on” cascade amplification for sensitive and accurate detection of phospholipase D in breast cancer cells with a low-background signal

Abstract

Here we developed a simple, sensitive and accurate PLD detection method based on a target-controlled gating liposome (TCGL) “off–on” cascade amplified strategy and personal glucose meters (PGMs). It showed excellent sensitivity with a detection limit of 0.005 U L⁻¹ and well performed PLD activity analysis in breast cancer cells and inhibitor drug screening.
