BSA stabilized tetraphenylethylene nanocrystals as aggregation-induced enhanced electrochemiluminescence emitters for ultrasensitive microRNA assay

Abstract

On the basis of BSA stabilized tetraphenylethylene nanocrystals (BSA-TPE NCs) as aggregation-induced enhanced electrochemiluminescence (ECL) emitters with high ECL efficiency and good biocompatibility, as well as molecular recognition between β-CD and ferrocene, an ultrasensitive and versatile ECL biosensing platform was constructed to achieve microRNA detection in cancer cells.
