Uric acid biosensor based on chemiluminescence detection using a nano-micro hybrid matrix

Iron nanoparticles decorated multi-wall carbon nanotubes modified carbon paste electrode as an electrochemical sensor for the simultaneous determination of uric acid in the presence of ascorbic acid, dopamine and l-tyrosine

“…As reported in the literature [71], the UA oxidation involved two electrons and hence the number 11 of protons taking part in the reaction is also suggested to be two. Scheme 1 represents the electrochemical oxidation mechanism of UA at FeMWCNTs/MCPE.…”

“…Though there are several diverse methods for the determination of UA such as chemiluminescence [11], ion exchange column chromatography [12], enzymatic [13], high performance liquid chromatography [14], spectrophotometry [15] and spectrofluorometry [16], these techniques have certain disadvantages such as their being often time consuming, expensive and complex. Electrochemical methods for UA determination have certain advantages such as simple, short detection time, reproducibility and ease of handling [17][18][19][20][21].…”

An electrochemical biosensor based on nanoporous stainless steel modified by gold and palladium nanoparticles for simultaneous determination of levodopa and uric acid

“…And there are many methods to detect the level of UA such as HPLC [17][18][19][20], spectrophotometry [21,22], chemiluminescence [23][24][25], surface-enhanced Raman scattering (SERS).…”

Fabrication of inorganic hydroxyapatite nanoparticles and organic biomolecules-dual encapsulated alginate microspheres

“…Chaudhari et al encapsulated pentacene-loaded peroxalate nanoparticles and Uricase into alginate microparticles for biosensor. 20 They claimed that the coencapsulation of Uricase and NIR dye to alginate microparticles would avoid complicated loading processes. Coradin and Livage utilized silica nanoparticles to immobilize enzyme, and the enzymeloaded silica nanoparticles were further mixed with alginate, forming a composite consisting of silica nanoparticles and alginate microparticles.…”
