A high sensitivity luminescent sensor for the stress biomarker cortisol using four-fold interpenetrated europium–organic frameworks integrated with logic gates

Abstract

A four-fold interpenetrated Ln-MOF (<bold>MHT-1</bold>) exhibits the excellent luminescence response to the stress biomarker cortisol, in which an intelligent logic gate based on <bold>MHT-1</bold> offers a simple approach to detect cortisol with the naked eye.
