Journal ArticleDOI
Extracellular electrical recording of pH-triggered bursts in C6 glioma cell populations
Paulo R. F. Rocha,Maria C. R. Medeiros,Ulrike Kintzel,Johannes Vogt,Inês M. Araújo,Ana L. G. Mestre,Volker Mailänder,Volker Mailänder,Paul Schlett,Melanie Dröge,Leonid Schneider,Fabio Biscarini,Dago M. de Leeuw,Dago M. de Leeuw,Henrique L. Gomes +14 more
TL;DR: This model of pH-triggered bursting was unambiguously supported by deliberate, external acidification of the cell culture medium and was likely to directly perturb, in vivo, the functionality of the healthy neuronal network in the vicinity of the tumor bulk and may contribute to seizures in glioma patients.
Journal ArticleDOI
An electrical method to measure low-frequency collective and synchronized cell activity using extracellular electrodes
Maria C. R. Medeiros,Ana L. G. Mestre,Pedro M. C. Inácio,Sanaz Asgarif,Inês M. Araújo,Peter C. Hubbard,Zélia Velez,M. Leonor Cancela,Paulo R. F. Rocha,Dago M. de Leeuw,Fabio Biscarini,Henrique L. Gomes +11 more
TL;DR: An electrical method to measure extracellular bioelectrical activity in vitro using the Helmholtz capacitive double-layer established at the electrode surface that is an ideal tool to measure in vitro slow and temporally synchronized events that are often involved in long range intracellular signaling.
Journal ArticleDOI
Bioelectrical Signal Detection Using Conducting Polymer Electrodes and the Displacement Current Method
Pedro M. C. Inácio,Ana L. G. Mestre,Maria C. R. Medeiros,Sanaz Asgarifar,Youssef Elamine,Joana Canudo,João M.A. Santos,José Bragança,Jorge Morgado,Fabio Biscarini,Henrique L. Gomes +10 more
TL;DR: In this article, the displacement current method combined with high capacitive polymer-based electrodes is proposed to measure clusters of cells and whole organs, which has great potential in fundamental studies of drug discovery and safety pharmacology.
Journal ArticleDOI
Ultra-low noise PEDOT:PSS electrodes on bacterial cellulose: A sensor to access bioelectrical signals in non-electrogenic cells
Pedro M. C. Inácio,Maria C. R. Medeiros,Tiago Carvalho,Rute C. Félix,Ana L. G. Mestre,Peter C. Hubbard,Quirina Ferreira,Jorge Morgado,Ana Charas,Carmen S. R. Freire,Fabio Biscarini,Fabio Biscarini,Deborah M. Power,Henrique L. Gomes +13 more
TL;DR: In this article, the authors demonstrate that the coating of cellulose nanofibers with conducting PEDOT:PSS ink allows the fabrication of a nanostructured surface that establishes a low electrical double-layer resistance with liquid solutions.
Journal ArticleDOI
Ultrasensitive gold micro-structured electrodes enabling the detection of extra-cellular long-lasting potentials in astrocytes populations
Ana L. G. Mestre,Mónica Cerquido,Pedro M. C. Inácio,Sanaz Asgarifar,Ana Sofia Lourenço,Maria Lurdes Santos Cristiano,Paulo Aguiar,Maria C. R. Medeiros,Inês M. Araújo,João Ventura,Henrique L. Gomes +10 more
TL;DR: The electrodes and the methodology developed here can be used as an ultrasensitive electrophysiological tool to reveal the synchronization dynamics of ultra-slow ionic signalling between non-electrogenic cells.
