González-Segura, Karina; Cañete Rosales, Paulina; Del Rio, Rodrigo; Yáñez, Claudia; Ferreyra, Nancy F.; Rivas, Gustavo A.; Bollo Dragnic, Soledad (2012)The electrochemical response of a glassy carbon electrode modified with carbon nanotubes (CNT) dispersed in two solvents, water and DMF, and two polymers, chitosan and Nafion is reported. The films were homogeneous when ...

Luque, Guillermina L.; Ferreyra, Nancy F.; Granero, Adrián; Bollo Dragnic, Soledad; Rivas, Gustavo A. (2011)This work reports the electrochemical response of the complex between dsDNA and PEI formed in solution and at the surface of glassy carbon electrodes (GCE) modified with a dispersion of multi-walled carbon nanotubes in ...

Arias, Paulina; Ferreyra, Nancy F.; Rivas, Gustavo A.; Bollo Dragnic, Soledad (Elsevier, 2009)In this work we report the optimization of a chitosan (CHI) and carbon nanotubes (CNT) modified electrode, CNT-CHI, to study the dsDNA interaction with methylene blue (MB), a well-known DNA intercalator. The analytical ...

Sandoval Altamirano, Catalina; Sánchez, Susana A.; Ferreyra, Nancy F.; Günther Sapunar, Germán (Elsevier, 2017)The specificity of carbohydrate-protein interaction is a key factor in many biological processes and it isthe foundation of technologies using glycoliposomes in drug delivery. The incorporation of glycolipidsin vesicles ...
