“…The results obtained are shown in Figure 1. The results correspond to those presented in other specific research studies, the differences being due to the particularity of the electrode (e.g., surface area, support material) and to the voltammetric technique (potential range, scan rate) [53,60].…”

“…Cobalt Phthalocyanine, an organic semiconductor ensuring sensor stability and sensitivity is another modifier used in the development of CMEs [44][45][46][47]. Due to its chemical composition, Prussian Blue has very good electrochemical properties, being most frequently used in the manufacture of electrochemical (bio)sensors detecting hydrogen peroxide [48][49][50][51][52][53][54][55][56]. These electroactive materials could be used for the development of novel electrochemical sensors for different analysts of great importance such is Phe.…”

This paper describes the sensitive properties of screen-printed carbon electrodes (SPCE) modified by using three different electroactive chemical compounds: Meldola’s Blue, Cobalt Phthalocyanine and Prussian Blue, respectively. It was demonstrated that the Prussian Blue (PB) modified SPCE presented electrochemical signals with the highest performances in terms of electrochemical process kinetics and sensitivity in all the solutions analyzed. PB-SPCE was demonstrated to detect Phe through the influence it exerts on the redox processes of PB. The PB-SPCE calibration have shown a linearity range of 0.33–14.5 µM, a detection limit (LOD) of 1.23 × 10−8 M and the standard deviation relative to 3%. The PB-SPCE sensor was used to determine Phe by means of calibration and standard addition techniques on pure samples, on simple pharmaceutical samples or on multicomponent pharmaceutical samples. Direct determination of the concentration of 4 × 10−6–5 × 10−5 M Phe in KCl solution showed that the analytical recovery falls in the range of 99.75–100.28%, and relative standard deviations in the range of 2.28–3.02%. The sensors were successfully applied to determine the Phe in pharmaceuticals. The validation of the method was performed by using the FTIR, and by comparing the results obtained by PB-SPCE in the analysis of three pharmaceutical products of different concentrations with those indicated by the producer.

New faces of porous Prussian blue: interfacial assembly of integrated hetero-structures for sensing applications

et al. 2015

View full text Add to dashboard Cite

Prussian blue (PB), the oldest synthetic coordination compound, is a classic and fascinating transition metal coordination material. Prussian blue is based on a three-dimensional (3-D) cubic polymeric porous network consisting of alternating ferric and ferrous ions, which provides facile assembly as well as precise interaction with active sites at functional interfaces. A fundamental understanding of the assembly mechanism of PB hetero-interfaces is essential to enable the full potential applications of PB crystals, including chemical sensing, catalysis, gas storage, drug delivery and electronic displays. Developing controlled assembly methods towards functionally integrated hetero-interfaces with adjustable sizes and morphology of PB crystals is necessary. A key point in the functional interface and device integration of PB nanocrystals is the fabrication of hetero-interfaces in a well-defined and oriented fashion on given substrates. This review will bring together these key aspects of the hetero-interfaces of PB nanocrystals, ranging from structure and properties, interfacial assembly strategies, to integrated hetero-structures for diverse sensing.

“…The nanostructured Prussian blue (PB), known as an artificial peroxidase, has been extensively used for H 2 O 2 detection and was a fundamental material for possible mass production of glucose biosensors [10−13], due to its excellent catalysis for H 2 O 2 reduction at low potentials compared to noble metal, and a relatively cheap and stable electro-catalyst compared to enzyme [10, 13−15]. However, the current response decreases quickly in neutral and alkaline solutions [12]. The operational stability of PB seems to be dependent on the structure regularity of PB film.…”

The Prussian blue/ionic liquid-polyaniline/multiwall carbon nanotubes (PB/IL-PANI/ MWNTs) composite film was fabricated by using cyclic voltammetry. The ion liquid acting as a lubricating agent, could enhance the electron delocalization degree and reduce the structural defects of the polyaniline. The surface morphology of the composite film revealed that the PB nanoparticles have smaller size than that in pure PB film. Due to the introduction of ion liquid, the PB/IL-PANI/MWNTs composite film showed wonderful synergistic effect which can remarkably enhance sensitivity, expand linear range and broaden acidic adaptability for hydrogen peroxide detection. The composite film demonstrated good stability in neutral solution contrast to pure PB film, with a linear range from 2.5 µmol/L to 0.5 mmol/L and a high sensitivity of 736.8 µA•(mmol/L) −1 •cm −2 for H 2 O 2 detection. Based on the composite film, an amperometric glucose biosensor was then fabricated by immobilizing glucose oxidase. Under the optimal conditions, the biosensor also exhibits excellent response to glucose with the linear range from 12.5 µmol/L to 1.75 mmol/L and a high sensitivity of 94.79 µA•(mmol/L) −1 •cm −2 for H 2 O 2. The detection limit was estimated 1.1 µmol/L. The resulting biosensor was applied to detect the blood sugar in human serum samples without any pretreatment, and the results were comparatively in agreement with the clinical assay.
