PEREZ-CORDOVES, Ana Isa; BALBIN-TAMAYO, Abel Ibrahim; MARDINI-FARIAS, Pércio Augusto  e  COSTA-MOREIRA, Josino. Study of Polypyrrole Electropolymerization in the Presence of a Chiral Acid. Rev Cub Quim [online]. 2017, vol.29, n.1, pp. 39-53. ISSN 2224-5421.

In this paper we address the study of the modification of electrodes with polypyrrole and a chiral inductor for use on the recognition of chiral drugs, that can bring the selectivity and sensitivity required for the use of simpler approaches of analysis for the detection of chiral drugs in complex samples with detection limits compared to the very elaborate procedures and complex instrumentation of employment and high maintenance costs and acquisition that predominate today. The techniques used for research were cyclic voltamperometry and crhonoculombimetry. Acid Canphorsulfonic (CSA) was used as chiral inductor. The results showed that in the case of pyrrol/CSA study system shows two peaks suggesting different electropolimerization form by the presence of CSA. Also electroactive area was calculated by determining the electrode is greater than the geometric area, thus demonstrating that the modified surface has a higher electroactivity.
