Electrochemical biosensing based on noble metal nanoparticles

Disposable Biosensors for Clinical Diagnosis

“…measurable signal. [13][14][15] Various analytes of environmental, medical, biological, pharmaceutical, or industrial interest can be monitored using an electrochemical biosensor, which provides a measure of the analyte concentration by detecting the current generated in the oxidation or reduction of the redox species. 16 In electrochemical biosensors, the biological material is directly immobilized on a electrode by adsorption, covalent bonding, or encapsulation within a coating layer of a permeable conductive polymer or cross-linked reagent.…”

Bienzymatic glucose biosensor based on direct electrochemistry of cytochrome c on gold nanoparticles/polyaniline nanospheres composite

“…Recently, nanomaterials are widely used to realize the direct electrochemistry of Cyt c, as they have large surface area, good biocompatibility and/or conductivity, which can facilitate the electron transfer between enzyme and the underlying electrodes [7][8][9][10]. In particular, conducting polymer, which are a new type of nanomaterials, have been extensively studied for the fabrication of new classes of advanced materials because of their remarkable electronic and biocompatible properties combined with high chemical stability.…”

Application of Electrochemical Methods in Biosensing Technologies

“…Noble metal nanoparticles (NPs) due to great conductivity, biocompatibility, high surfaceto-volume ratio and modification possibilities by hybridization, sol-gel, self-assembly monolayer (SAM) and others methods are very popular and available on the market [16]. Currently, nanomaterials are essential in bio-devices due to enhanced sensitivity and detection limits [17].…”

“…Currently, nanomaterials are essential in bio-devices due to enhanced sensitivity and detection limits [17]. Well-known are AuNPs, AgNPs, PtNPs, and their alloys Au-Ag, Au-Pt, Ag-Pt [16] …”
