Chem Commun (Camb). 2015 Jan 28;51(8):1472-4. doi: 10.1039/c4cc08860c.

Abstract

In this work, a sensitive electrochemical aptasensor for the detection of thrombin (TB) is developed and demonstrated based on the co-catalysis of hemin/G-quadruplex, platinum nanoparticles (PtNPs) and flower-like MnO2 nanosphere functionalized multi-walled carbon nanotubes (MWCNT-MnO2).
