Prussian Blue based screen printed biosensors with improved characteristics of long-term lifetime and pH stability.
The promising advantages of Prussian Blue (PB) as catalyst and of the thick film screen printing technology have been combined to assemble sensors with improved characteristics for the amperometric determination of H(2)O(2). PB-modified screen printed electrodes were applied to detect H(2)O(2) at an applied potential of -0.05 V versus the internal screen printed Ag pseudoreference electrode, sh...
متن کاملDevelopment of a Hydrogen Peroxide Sensor Based on Screen-Printed Electrodes Modified with Inkjet-Printed Prussian Blue Nanoparticles
A sensor for the simple and sensitive measurement of hydrogen peroxide has been developed which is based on screen printed electrodes (SPEs) modified with Prussian blue nanoparticles (PBNPs) deposited using piezoelectric inkjet printing. PBNP-modified SPEs were characterized using physical and electrochemical techniques to optimize the PBNP layer thickness and electroanalytical conditions for o...
متن کاملAcetylcholinesterase sensor based on screen-printed carbon electrode modified with prussian blue.
Acetylcholinesterase (ChE) sensor based on Prussian blue (PB) modified electrode was developed and tested for the detection of organophosphorus and carbamic pesticides. The signal of the sensor was generated in PB mediated oxidation of thiocholine recorded at +200 mv in DC mode. ChE from electric eel was immobilized by cross-linking with glutaraldehyde in the presence of bovine serum albumin (B...
متن کاملElectrochromic device with Prussian blue and HPC-based electrolyte
Given the importance of the development of electrochromic devices (ECDs) for technological applications small devices with Prussian blue (PB)/hydroxypropyl cellulose (HPC) electrolyte/CeO2TiO2 configuration were assembled and characterized. The films of PB were obtained galvanostaticaly by applying 0.45 mA for 300 s. The cyclic voltammetry, in 1 mol L 1 KCl solution, of these films showed a red...
متن کاملElectrochemical Affinity Biosensors Based on Disposable Screen-Printed Electrodes for Detection of Food Allergens
Food allergens are proteins from nuts and tree nuts, fish, shellfish, wheat, soy, eggs or milk which trigger severe adverse reactions in the human body, involving IgE-type antibodies. Sensitive detection of allergens in a large variety of food matrices has become increasingly important considering the emergence of functional foods and new food manufacturing technologies. For example, proteins s...
