Autor: Larissa Moreira Ferreira, Faruk Jose Nome Aguilera, Iolanda Cruz Vieira, Franciane D. Souza

Publikováno v: Canadian Journal of Chemistry. 95:113-119

A new sensor was developed for the analysis of phenolic compounds by coating the surface of a glassy carbon electrode (GCE) with rhodium nanoparticles stabilized in 3-(1-tetradecyl-3-imidazolium) propanesulfonate (ImS3-14), a zwitterionic surfactant.

Publikováno v: Langmuir. 31:3587-3595

This paper presents the physicochemical properties of micellar aggregates formed from a series of zwitterionic surfactants of the type 3-(1-alkyl-3-imidazolio)propane-sulfonate (ImS3-n), with n = 10, 12, 14, and 16. The ImS3-n dipolar ionic surfactan

The chameleon effect in zwitterionic micelles: Binding of anions and cations and use as nanoparticle stabilizing agents

Autor: Haidi D. Fiedler, Franciane D. Souza, Faruk Nome, Emma E. Drinkel

Publikováno v: Current Opinion in Colloid & Interface Science. 18:26-34

Zwitterionic surfactants are relatively overlooked and some of their properties resemble those of ionic and non-ionic surfactants, but others are unique. There is unimpeachable evidence that aqueous solutions of zwitterionic micelles interact specifi

Gold nanoparticles dispersed in zwitterionic surfactant for peroxidase immobilization in biosensor construction

Autor: Iolanda Cruz Vieira, Bruno S. Souza, Faruk Nome, Suellen Cadorin Fernandes, Franciane D. Souza

Publikováno v: Sensors and Actuators B: Chemical. 173:483-490

In this study, peroxidase from alfalfa sprout extract (Medicago sativa) was immobilized on a gold electrode, using a solution of the zwitterionic surfactant 3-(1-tetradecyl-3-imidazolio)propanesulfonate (ImS3-14) containing well-dispersed gold nanopa

Publikováno v: Analytical chemistry. 85(21)

A selective method is proposed for the determination of palladium, gold, and sulfur in catalytic systems, by direct liquid analysis using energy dispersive X-ray fluorescence (EDXRF), under an atmosphere of helium or air. This method allows a nondest

Addition of salts, especially perchlorates, to zwitterionic micelles of SB3-14, C(14)H(29)NMe(2)(+)(CH(2))(3)SO(3)(-), induces anionic character and uptake of H(3)O(+) by SB3-14 micelles. Thus, the addition of alkali metal perchlorates accelerates th
