An electrochemiluminescent sensor based on ZnPTC@MoS2 nanocomposite for sensitive determination of trilobatin.

In this work, a sensitive electrochemiluminescence (ECL) sensing platform was developed for the determination of trilobatin (Tri) using a ZnPTC@MoS2-modified glassy carbon electrode. In this sensing interface, ZnPTC acts as both an intrinsically ECL-active metal-organic framework and a structural scaffold, while MoS2 n...

Triple-ligand engineered gold nanoclusters with aggregation-induced emission for a high-sensitivity arginase activity electrochemiluminescence biosensor.

Sensitive and accurate monitoring of arginase activity is significant for clinical diagnosis. Herein, a dual-enhanced aggregation-induced electrochemiluminescence (ECL) biosensor was constructed based on triple-ligand-protected gold nanoclusters (AuNCs), sequentially coating 6-aza-2-thiothymine-capped AuNCs with L-argi...

An electrochemiluminescent aptasensor based on porphyrin-based covalent organic framework for the sensitive detection of kanamycin.

Herein, an electrochemiluminescent (ECL) aptasensor based on porphyrin-based covalent organic framework (TP-COF) was constructed for the ultrasensitive detection of kanamycin (KANA). The ordered porous channels and porphyrin-centered π-conjugated framework of TP-COF optimize the interfacial microenvironment and acceler...
