Single-walled　carbon　nanotube　(SWNT)　was　functionalized　with　N-n-octadecyl-D-maltonamide　(NOMA),　a　simple　sugar-containing　amphipathic　compound,　by　a　method　of　noncovalent　adsorption　to　form　a　NOMA-SWNT　nanocomposite.　The　spectroscopic　and　morphology　results　show　that　NOMA　could　be　rapidly　and　effectively　adsorbed　on　the　surface　of　SWNT　without　changing　the　native　structure　of　NOMA　and　the　structure　properties　of　SWNT.　Moreover,　it　was　shown　that　the　dispersion　ability　of　SWNT　in　aqueous　solution　had　a　significant　improvement　after　coating　with　NOMA.　Field　effect　transistor(FET)　devices　with　a　NOMA-SWNT　bundle　as　the　conducting　channel　have　been　developed　to　detect　maltose-Concanavalin　A(Con　A)　interaction.　Obvious　changes　in　the　Carbon　nanotube　field　effect　transistor(CNTFET)　characteristics　have　been　detected　after　NOMA　functionalization　and　after　Con　A　adsorption　to　the　NOMA　coating　layer,　which　demenstrates　the　possobility　of　noncovalent　glycosylated　functionalization　of　SWNTs　with　simple　molecue　NOMA　and　sugar-lectin　recognition　detection　by　CNTFET.　The　presented　method　for　functionalization　of　SWNT　had　several　advantages,　Such　as　rapid　and　facile　CNT　functionalization,　good　hydrophilicity　and　biocompatibility,　versatile　detection　of　receptor　via　various　glycoligand　molecule,　etc.,　and　could　be　used　for　bio-functionalized　materials,　detection　of　carbohydrate-protein　interactions　and　diagnose　processes　of　deleterious　disease.
