31 p, 1.9 MB Use of nanomaterials for impedimetric DNA sensors : a review / Bonanni, Alessandra (Universitat Autònoma de Barcelona. Grup Sensors i Biosensors) ; Valle Zafra, Manuel del (Universitat Autònoma de Barcelona. Departament de Química)
This review presents the state of the art of DNA sensors (or genosensors) that utilize electrochemical impedance spectroscopy as the transduction technique. As issue of current interest, it is centered on the use of nanomaterials to develop or to improve performance of these specific biosensors. [...]

23 p, 6.5 MB DNA polymorphism sensitive impedimetric detection on gold-nanoislands modified electrodes / Bonanni, Alessandra (Nanyang Technological University. School of Physical and Mathematical Sciences) ; Pividori, María Isabel (Universitat Autònoma de Barcelona. Departament de Química) ; Valle Zafra, Manuel del (Universitat Autònoma de Barcelona. Grup de Sensors i Biosensors)
Nanocomposite materials are being increasingly used in biosensing applications as they can significantly improve biosensor performance. Here we report the use of a novel impedimetric genosensor based on gold nanoparticles graphite–epoxy nanocomposite (nanoAu–GEC) for the detection of triple base mutation deletion in a cystic-fibrosis (CF) related human DNA sequence. [...]
