One-step synthesis of fluorescently labelled, single-walled carbon nanotubes

Abstract

Single-walled carbon nanotubes (SWNTs) can be labelled with functional moieties that endow them with a number of unique characteristics, which can be applicable to biomedical applications such as imaging. Herein we describe a facile, one-step esterification process to functionalize SWNT with fluorescein.

Solution processed, vertically stacked hetero-structured diodes based on liquid-exfoliated WS2 nanosheets: from electrode-limited to bulk-limited behavior

“…The absorption peaks for I-SWNTs and S-SWNTs can be observed at around 700 nm and 1022 nm, corresponding to M 11 metallic and S 22 semiconducting characteristic peaks 35 respectively, with no obvious dependence on dispersing medium.…”

Hybrid, dual visible and near-infrared fluorescence emission of (6,5) single-walled carbon nanotubes modified with fluorescein through aryl diazonium salt chemistry

“…With that in mind, we plan to explore more deeply the area of fluorophore-SWCNTs interactions in the future. Our approach for direct attachment of fluorescein to SWCNTs is unique among others [53][54][55], as not only fluorescent properties of fluorescein are well-preserved, but more importantly, SWCNTs are not a simple carrier of the functional molecule but effectively benefit from its attachment.…”
