关键词: A logic AND gate Activatable Microwave thermal therapy Real-time imaging Theranostics

摘要:
In vivo monitoring of treatment response is of great significance for tumor therapy in clinical trials, but it remains a formidable challenge. Herein, we demonstrate a logic AND gate theranostic nanoagent that responds to the coexistence of endogenous and exogenous stimuli, namely HAuCl4@1-Tetradecanol@Gd-based metal-organic framework@SiO2 nanocomposites (APGS NCs). Upon microwave (MW) irradiation, HAuCl4 in the inner part of APGS NCs reacts with the tumor-associated glutathione (GSH). Subsequently, it transforms into an active luminescent form of Au@1-Tetradecanol@Gd-MOF@SiO2 nanocomposites (AuPGS NCs). The intensity of generated fluorescence is correlated with the tumor thermal-injury status. Thus, the generation of AuPGS NCs with high intensity fluorescence under the co-activation of MW and GSH can visualize the treatment effects during MW thermal therapy and instantly modulate the irradiation time and range for optimal outcomes. Hence, this logic gate controlled APGS NCs makes MW thermal therapy eliminate tumor cells completely. This research offers an effective strategy for the design and preparation of activatable theranostic nanoagents for precise tumor imaging and therapy.Copyright © 2023 Elsevier Ltd.
