Metal–Organic Framework-Functionalized Paper-Based Electrochemical Biosensor for Ultrasensitive Exosome Assay

Analytical Chemistry, 2021
The exosome has emerged as a promising noninvasive biomarker for the early diagnosis of cancer. Therefore, it is highly desirable to develop simple, inexpensive, and user-friendly biosensors for convenient, sensitive, and quantitative exosome assay. Herein, we developed a simple and cost-efficient electrochemical biosensor by combining a metal-organic ...

Copper-based metal–organic xerogels on paper for chemiluminescence detection of dopamine

Analytical Methods, 2020
Copper(ii)-containing metal–organic xerogels (Cu-MOXs), was produced and Cu-MOXs can catalyze the chemiluminescence of luminol–H2O2 system. Dopamine can be detected with the inhibition effect on Cu-MOXs–luminol–H2O2 system.
