Provided herein is a drug delivery (DD) system for ratiometric luminescence determination of drug release degree in drug delivery monitoring, which includes a drug, a switchable reporter and non-switchable reporter providing two distinguishable signals for detection; or a single switchable reporter providing two distinguishable signals for detection, and a cleavable linker connecting a drug to a switchable reporter, as well as a method for ratiometric luminescence determination of drug release in a target in vivo or in vitro), which is effected by administering the DD system provided herein that is capable of releasing a drug from the DD system, measuring two luminescent signals provided by the switchable reporter and the non-switchable reporter, or the single switchable reporter, determining the ratio between these two luminescence signals, and determining the drug release degree through the ratio between the two luminescence signals.
本文提供了一种药物递送(DD)系统,用于药物递送监测中药物释放程度的比例荧光测定,该系统包括一种药物、一种可切换的报告物和一种不可切换的报告物,用于提供两种可区分的信号以进行检测;或者一种单一可切换的报告物,用于提供两种可区分的信号以进行检测,以及一种可切割的连接剂,连接药物和可切换的报告物,以及一种比例荧光测定方法,用于在目标(体内或体外)中测定药物释放,通过给予本文提供的能够从DD系统中释放药物的DD系统,测量可切换的报告物和不可切换的报告物提供的两个发光信号,或者单一可切换的报告物,确定这两个发光信号之间的比例,并通过这两个发光信号之间的比例确定药物释放程度。
