Electrocatalytic determination of NADH by means of electrodes modified with MWCNTs and nitroaromatic compounds

Contreras, G.; Barrientos, C; Moscoso, R.; Álvarez Lueje, Alejandro; Squella Serrano, Juan (Elsevier, 2020)

In this work, we have both synthesized and studied 4-phenylbutyl-3,5-dinitrobenzoate (3,5-DNBPh) as a potential precursor of an electrocatalytic mediator for the oxidation of NADH, with the di-nitro compound immobilized ...

Electrochemistry and reactivity against superoxide anion radicals of hydroxycoumarins and its derivatives

Barrientos, C; Navarrete Encina, P.; Squella Serrano, Juan (Electrochemical Soc Inc, 2020)

The present studies reveal superoxide radical anion reactivity against synthesized coumarins. Free radicals play an important role in many diseases and they have a protective function also. Therefore, we must keep a balance ...

New voltammetric method useful for water insoluble or weakly soluble compounds: application to pKa determination ...

Barrientos, C; Navarrete-Encina, P.A.; Carbajo, J.; Squella Serrano, Juan (Springer, 2018)

Here, we reveal a different way of doing the voltammetric experiments that considers the electroactive species packaged in the electrodic phase instead of dissolved in solution. In this way, it is possible to obtain ...
