Fabrication of hybridized single-walled carbon nanotube (SWNT) device based on novel sensing material N-4-Hexafluoroisopropanolphenyl-1-pyrenebutyramide (HFIPP) via facile approach has been reported for the first time. Considered that strong hydrogen-bonding can be formed between HFIPP and dimethyl methylphosphonate (DMMP) (simulant of...
