Disposable CNFs electrodes were fabricated after filtering CNFs through polytetrafluoroethylene filters (PTFE), using directly as electrodes these filters with the CNFs film. The electrochemical behaviour of CNFs/PTFE electrodes were tested with ferrocenemethanol and tris(2,2′-bypyridyl)dichlororuthenium(II) (Ru(bipy)32+). As a proof of concept of the analytical usefulness of the CNFs/PFTE electrodes, the study of vitamin B12 was carried out. Multivariate calibrate has been successfully used to determine vitamin B12 in a complex medium with vitamins B1 and B6 as interferents. 2018-09-12T11:39:55Z 2018-09-12T11:39:55Z 2016-04 info:eu-repo/semantics/article 1040-0397 http://hdl.handle.net/10259/4938 eng Electroanalysis. 2016, V. 28, n. 4, p. 890-897 https://doi.org/10.1002/elan.201500576 info:eu-repo/grantAgreement/JCyL/BU349-U13 info:eu-repo/grantAgreement/JCyL/GR71 info:eu-repo/grantAgreement/MINECO/CTQ2014-55583-R info:eu-repo/grantAgreement/MINECO/CTQ2014-61914-EXP info:eu-repo/semantics/openAccess Wiley
