NanoBioelectronics and Biosensors

Group Leader: Arben Merkoçi

Main Research Lines

  • Catalytic/carrier nanomaterials: nanoparticles as electrocatalysts, nanoparticles as biomolecule carriers, and nanowires/nanotubes for non-enzymatic/enzyme mimic sensors

  • Nanomicrofluidics and lab-on-a-chip technologies

  • Paper- and nanopaper-based nanobiosensors

  • Nanochannels: nanoporous membranes as electrical sensing platforms

  • Graphene: biosensors based on graphene-related materials

Nanobiosensors and Bioanalytical Applications

In 2021 the group has continued working on two large ongoing European projects. The first one, MICROB-PREDICT (Microbiome-based biomarkers to predict decompensation of liver cirrhosis and treatment response) aims to develop personalised strategies to prevent and treat decompensated cirrhosis and acute-on-chronic liver failure by investigating the human gut microbiome. The second one, CORE 3, is part of the Graphene Flagship project and focuses on the development of graphene-based sensors. A new European project was started in 2021, EMERGE (Emerging Printed Electronics Research Infrastructure), as well as two national projects: NANOANAEMIA (Multiplexed nanobiosensor for the instantaneous diagnosis and classification of anaemia at the point of care) and PAPYRUS (Polymerase Amplification combined into a Paper-based electrochemical lateral flow arraY for antimicrobial Resistance qUantification).

Arben Merkoçi

ICREA Research Professor

ICREA Research Professor and leader of the ICN2 Nanobioelectronics and Biosensors Group, Arben Merkoçi obtained his PhD at the University of Tirana (Albania) in ion selective electrodes. Since 1992 he has carried out research as postdoctoral fellow and research professor at the Polytechnic University of Budapest (Hungary), University of Ioannina (Greece), Università degli Studi di Padova (Italy), Universitat Politècnica de Catalunya, Universitat Autònoma de Barcelona and New Mexico State University (USA). His research is focused on the integration of biological molecules and other species with micro- and nanostructures to design novel (bio)sensors. He is member of the Academy of Sciences of Albania and director and coordinator of NANOALB (, the regional network of nanoscience and nanotechnology.

Prof. Merkoçi is Co-Editor in Chief of Biosensors and Bioelectronics, the principal international journal devoted to research, design development and application of biosensors and bioelectronics, member of editorial board of Electroanalysis, Microchimica Acta and other journals.

Prof. Merkoçi has published 332 articles (H-index / citations: Google Scholar 85 / 26466; WOS 74 / 19971) and supervised 44 PhD theses. He is also involved in teaching PhD courses in the field of nanomaterial-based biosensors in several Spanish and international centres. He has been a member of the commission for establishing the new Nanoscience and Nanotechnology undergraduate academic curriculum at the UAB, the first one in Spain, which started during the academic year 2010-2011. He is a member of the Academics Working Group of BIST and coordinator of the Nanodiagnostics module of the Nanotechnology Master at the UAB.
