•A general and effective method to functionalize pristine SWNTs.•Microwave radiation greatly facilitated reaction kinetics.•Carbohydrate–SWNT conjugates showed good bioaffinity and binding selectivity.
Carbohydrate–functionalized single-walled carbon nanotubes (SWNTs) were synthesized using microwave-assisted reaction of perfluorophenyl azide with the nanotubes. The results showed that microwave radiation provides a rapid and effective means to covalently attach carbohydrates to SWNTs, producing carbohydrate–SWNT conjugates for biorecognition. The carbohydrate–functionalized SWNTs were furthermore shown to interact specifically with cognate carbohydrate-specific proteins (lectins), resulting in predicted recognition patterns. The carbohydrate-presenting SWNTs constitute a new platform for sensitive protein- or cell recognition, which pave the way for glycoconjugated carbon nanomaterials in biorecognition applications.
