Glucose level determination in single cells in their satiety and starvation states using an enzymatic functional glass nanopore

Abstract

A cytochrome c (Cyt c)-modified glass nanopore sensing platform was constructed to sensitively detect glucose in single cells based on changes in the ionic current rectification (ICR) of the system. A difference in glucose content between single H8 and HeLa cells in their satiety or starvation states was clearly able to be detected using this method.
