Voltammetric detection of As(III) with Porphyridium cruentum based modified carbon paste electrode biosensor

Electrochemical determination of inorganic mercury and arsenic—A review

“…For As(III), the first ever microbial biomass based carbon paste electrode had been reported by our research group recently. This biologically modified electrode employed red micro algal specie (Porphyridium cruentum) and achieved a detection limit of 2.5 µg/L for As(III) detection (Zaib et al 2014). The interaction of metal ions with the modified carbon paste electrode and the simplification of the process is shown in Figure 4.…”

Molecular imprinting method for fabricating novel glucose sensor: Polyvinyl acetate electrode reinforced by MnO2/CuO loaded on graphene oxide nanoparticles

“…Because of their selectivity, MIPs are very attracted in electrochemistry to improve the electrode response to target molecules Hu et al, 2015;Tiwari & Prasad, 2015;Toro et al, 2015). Due to advantages of chemically modified carbon paste electrodes, such as simplicity, easy fabrication, low cost, renewable surface, physical and chemical stability, they have been extensively applied in various electrochemical research, such as sensors preparation (Gholivand et al, 2015;Zaib et al, 2014). These advantages make MIPs more attractive than natural biological receptors.…”

Electroanalytical Detection of Cr(VI) and Cr(III) Ions Using a Novel Microbial Sensor

“…Carbon paste electrode modified using a red algae, Porphyridium cruentum , was used for the voltammetric detection of As(III) ions in contaminated water, that gave a lowest detection limit of about 3.3x10 −8 M . CPE modified using Bacillus sp ., was employed to detect gold (Au(III)) and copper (Cu(II)) using the stripping voltammetric technique . In another work, Pseudomonas aeruginosa modified CPE was used to detect lead (Pb(II)) ions using cyclic voltammetry and differential pulse anodic stripping voltammetric techniques for which a LLOD of 6x10 −7 M of Pb(II) was achieved .…”
