A highly performed nonenzymatic glucose sensor using surfactant template assisted platinum nanoparticles

In this work, we have successfully developed an enzyme free glucose sensor with highly performed electrodes, which was decorated with surfactant assisted platinum nanoparticles (PtNPs) on rectangular shaped thin Au film electrode. The PtNPs have been used for their outstanding catalytic activity for the redox reaction of H

. Diblock copolymer surfactant template was used to deposit platinum nanoparticles on the working and counter electrodes, simultaneously. Optimal potential was investigated and applied for the uniform distribution of PtNPs. The fabricated biosensor showed good electrocatalytic performance in terms of high sensitivity of 0.32 μA/mM, fast response of 5 s, and wide linear range from 0.0625 to 22 mM.
