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 ...

Primo, Emiliano N.; Bollo Dragnic, Soledad; Rubianes, María D.; Rivas, Gustavo A. (Pergamon-Elsevier Science LTD, 2018)This work is focused on the critical analysis of the non-covalent modification of a thiolated-gold surface with different grapheneous materials and the covalent attachment of bovine serum albumin (BSA) as a model protein. ...

Primo, Emiliano N.; Kogan Bocian, Marcelo; Verdejo, Hugo E.; Bollo Dragnic, Soledad; Rubianes, María D.; Rivas, Gustavo A. (American Chemical Society, 2018)© 2018 American Chemical Society. We report the first optical biosensor for the novel and important cardiac biomarker, galectin-3 (Gal3), using the anti-Gal3 antibody as a biorecognition element and surface plasmon resonance ...
