Bracamonte, María V.; Yáñez Soto, Claudia; Bollo Dragnic, Soledad; Rivas, Gustavo A.; Ferreyra, Nancy F. (Elsevier, 2014)In this work, we characterize the electrochemical behavior of a new ferrocenyl-modified, hyperbranched poly(ethylenimine) (HBPei-Fc). The effects of the ionic strength, pH and the nature of the anion of the supporting ...

Caballero, J.; Zamora Figueroa, Claudia Carolina; Aguayo, D.; Yáñez Soto, Claudia; González, F. D. (AMER CHEMICAL SOC, 2008-08-21)The interaction of progesterone with beta-cyclodextrin (beta-CD) was studied by differential pulse polarography. The aim of the present work was to study the effect of beta-CD on the electrochemical behavior of progesterone ...
