Primo, Emiliano N.; Cañete Rosales, Paulina; Bollo Dragnic, Soledad; Rubianes, María D.; Rivas, Gustavo A. (2013)We report for the first time the use of double stranded calf-thymus DNA (dsDNA) to successfully disperse bamboo-like multi-walled carbon nanotubes (bCNT). The dispersion and the modified electrodes were studied by different ...

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 ...

Cañete Rosales, Paulina; Ortega, Valeria; Álvarez Lueje, Alejandro; Bollo Dragnic, Soledad; González, Mónica; Ansón, Alejandro; Martínez, María Teresa (Elsevier, 2012)The influence of chemical oxidation on the electrochemical behavior against hydrogen peroxide of long and short multi-walled carbon nanotubes (MWCNT) has been investigated. Different degrees of oxidation with a sulfo-nitric ...
