Label-free ultrasensitive detection of telomerase activity via multiple telomeric hemin/G-quadruplex triggered polyaniline deposition and a DNA tetrahedron-structure regulated signal

Author affiliations

Abstract

Label-free detection of telomerase activity was done by using telomeric hemin/G-quadruplex triggered polyaniline deposition, not only on themselves but also on the DNA tetrahedron-structure (DTS). DTS size has a great impact on telomerase accessibility, reactivity and detection sensitivity. The method has been used to evaluate bladder cancer development.
