New anthracene–tetrathiafulvalene derivative-encapsulated SWNT nanocomposite and its application for biosensing

A novel anthracene–tetrathiafulvalene derivative has been synthesized and immobilized on single-walled carbon nanotubes through non-covalent sidewall functionalization. In this study, a novel anthracene–tetrathiafulvalene derivative has been synthesized and immobilized on single-walled carbon nanotu...

Description
Summary:A novel anthracene–tetrathiafulvalene derivative has been synthesized and immobilized on single-walled carbon nanotubes through non-covalent sidewall functionalization. In this study, a novel anthracene–tetrathiafulvalene derivative has been synthesized and immobilized on single-walled carbon nanotubes through non-covalent sidewall functionalization. The new anthracene–tetrathiafulvalene (TTF) derivative-encapsulated SWNT nanocomposites were characterized using SEM, TEM, and Raman spectra and were utilized for biomolecular recognition. Our observations demonstrate that the new anthracene–TTF derivative-encapsulated SWNT nanocomposites can readily facilitate the biosensing and sensitive detection of DNA, which could be further explored for promising applications in bioelectronics and biosensors.
