30 p, 6.1 MB Addressing the theoretical and experimental aspects of low-dimensional-materials-based fet immunosensors : a review / Martins, Ernane (Institut Català de Nanociència i Nanotecnologia) ; Pinotti, Luis Francisco (Universidade Estadual de Campinas. Faculdade de Engenharia Elétrica e de Computação) ; De Carvalho Castro Silva, Cecilia (MackGraphe - Graphene and Nanomaterials Research Center) ; Reily Rocha, Alexandre (Universidade Estadual Paulista Júlio de Mesquita Filho. Instituto de Física Teórica)
Electrochemical immunosensors (EI) have been widely investigated in the last several years. Among them, immunosensors based on low-dimensional materials (LDM) stand out, as they could provide a substantial gain in fabricating point-of-care devices, paving the way for fast, precise, and sensitive diagnosis of numerous severe illnesses. [...]

15 p, 3.2 MB Composite Electrodes Based on Carbon Materials Decorated with Hg Nanoparticles for the Simultaneous Detection of Cd(II), Pb(II) and Cu(II) / López Fernández, Laia (Universitat Autònoma de Barcelona. Departament de Química) ; Bastos Arrieta, Julio (Universitat de Barcelona) ; Palet i Ballús, Cristina (Universitat Autònoma de Barcelona. Departament de Química) ; Baeza Labat, Maria del Mar (Universitat Autònoma de Barcelona. Departament de Química)
Monitoring water quality has become a goal to prevent issues related to human health and environmental conditions. In this sense, the concentration of metal ions in water sources is screened, as these are considered persistent contaminants. [...]
