The stability of suspensions of multiwalled carbon nanotubes in organic solvents in the presence of triton X-165

Laser desorption/ionization mass spectrometric analysis of folic acid, vancomycin and Triton® X‐100 on variously functionalized carbon nanotubes

“…In contrast, functionalized CNTs produce only a few signals in the low‐mass region; therefore, the amount of the analyte that has to be applied on them in LDI experiments is much lower than on sinapinic acid. Moreover, higher signals of Triton ® X‐100 in LDI experiments with functionalized CNTs as assisting surfaces can be attributed to well‐known interactions between CNTs and surfactants . Triton ® X‐100 molecules wrap around CNTs, which allows effective transfer of the energy from CNTs to the analyte in the laser desorption process.…”
