Screen-printed biosensor chips with Prussian blue nanocubes for the detection of physiological analytes
نویسندگان
چکیده
A Prussian blue (PB) biosensor chip with the nanocubic crystals was fabricated in batch by a screen printing technique for the general detection of various physiological substances. Through a low-speed chemical synthesis approach, the nanostructure of PB slurry was well controlled to be a 100 nm nanocube by the synthesis temperature and reactant concentration. Then, PB slurry was screen-printed as the work-

Facile synthesis of Prussian blue nanocubes/silver nanowires network as a water-based ink for the direct screen-printed flexible biosensor chips.
The large-scale fabrication of nanocomposite based biosensors is always a challenge in the technology commercialization from laboratory to industry. In order to address this issue, we have designed a facile chemical method of fabricated nanocomposite ink applied to the screen-printed biosensor chip. This ink can be derived in the water through the in-situ growth of Prussian blue nanocubes (PBNC...
متن کاملA probe for NADH and H2O2 amperometric detection at low applied potential for oxidase and dehydrogenase based biosensor applications.
Modified screen-printed electrodes for amperometric detection of H(2)O(2) and nicotinamide adenine dinucleotide (NADH) at low applied potential are presented in this paper. The sensors are obtained by modifying the working electrode surface with Prussian Blue, a well known electrochemical mediator for H(2)O(2) reduction. The coupling of this sensor with phenazine methosulfate (PMS) in the worki...

In the present paper, a comparative study using Co-phthalocyanine and Prussian Blue-modified screen-printed electrodes, has been performed. Both the electrodes have demonstrated an easiness of preparation together with high sensitivity towards thicoholine (LOD=5 x 10(-7) and 5 x 10(-6) M for Co-phthalocyanine and Prussian Blue, respectively) with high potentialities for pesticide measurement. P...
متن کاملAmperometric biosensor based on Prussian Blue nanoparticle-modified screen-printed electrode for estimation of glucose-6-phosphate.
Glucose-6-phosphate (G6P) plays an important role in carbohydrate metabolism of all living organisms. Compared with the conventional analytical methods available for estimation of G6P, the biosensors having relative simplicity, specificity, low cost, and fast response time are a promising alternative. We have reported a G6P biosensor based on screen-printed electrode using Prussian Blue (PB) na...
متن کاملPrussian blue nanocubes decorated three-dimensional silver nanowires network for high-performance electrochemical biosensing
High sensitivity and selectivity play critical roles in practical applications of glucose biosensors. In this study, we reported a novel glucose biosensor based on three-dimensional (3D) structured biosensing film, which consisted of silver nanowires (AgNWs) network and Prussian blue nanocubes (PBNCs). 3D AgNWs network was successfully built on the electrode surface with assistance of self-asse...
