Hydrogen sulfide detection by poly(methylene blue) modified highly oriented pyrolytic graphite electrode

AISI 304 Stainless Steel as a Transducer Substrate in Electrochemical Biosensors for Medical Applications

“…evance. For this purpose, the corrosion resistance of the material was analyzed in four media where biosensors are commonly employed at their work condition: Tris buffer, which is used to prepare biological solutions and to store sensors in appropriate conditions of salt concentration and pH [12][13][14]; an electrolyte containing potassium chloride, which is an aqueous solution commonly used in the literature due to its good conductivity to perform electrochemical measurements [15,16]; Hanks' solution, which is a synthetic solution that simulates body conditions and it is one option constantly considered in corrosion studies of environmental body influence [17][18][19][20]; and a ( ) ( )…”

Construction of Poly(methylene blue)/Copper Nanowires Modified Electrode for High-Performance Luteolin Sensing

“…The obtained polymer film by this technique shows high stability and electrical conductivity, and its thickness can be controlled by scanning cycles. 23,24 At present, electroactive polymer films of dyes have been introduced in the fabrication of modified electrodes considering their high electron transfer efficiency and low cost. [25][26][27] Methylene blue (MB) acts as an attractive water-soluble phenothiazine-based cationic dye, possessing a highly conjugated ringshaped structure with electron-rich sulfur and nitrogen atoms.…”
