Voltammetric sensor based on ordered mesoporous carbon for folic acid determination

Facile one-step direct electrodeposition of bismuth nanowires on glassy carbon electrode for selective determination of folic acid

“…The peak at -0.480 V is due to the reduction of folic acid to 5, 8-dihydrofolic acid [36]. (Table 1).…”

“…chemically modified electrodes have been used for the quantification of FA which include carbon nanotubes [1,32,33], carbon paste [34,35], ordered mesoporous carbon [36,37], calixarene [38], lead film electrode [39], nanostructured α-Fe 2 O 3 [40], phosphomolybdicpolypyrrole film [41] and 2-mercaptobenzothiazole self-assembled gold electrode [42]. All these modified electrodes are used for the determination of FA based on its oxidation reaction.…”

“…This is because of high surface-to-volume ratio of BiNWs along with uniform pore size of surfaces facilitating fast electron transfer kinetics of FA electro-reduction. Recently, Yang et al[20] and Ershad et al[36] observed reduction of FA at -0.670 V and -0.700 V on mesoporous carbon and polyaniline/MWCNT modified electrode respectively. However, compared to the present case of BiNWs/GC, these potentials are nearly -0.05 V and -0.08 V higher than those reported in literature, respectively.…”

Folic acid determination using electrochemical sensors

“…Due to the good characteristics of OMC, FA exhibited an enhanced EC response and lower reduction potential in the neutral solution. They observed that the peak current changes were linear with FA concentration changes in the range of 5.0 × 10 −10 to 1.0 × 10 −7 M with a lower detection limit of 6.0 × 10 −11 M.[ 17 ] Ojani et al . prepared poly (O-anisidine) (POA) modified carbon paste electrode (POA/MCPE) with electropolymerization of O-aminophenol on CPE in the presence of sodium dodecyl sulfate.…”

Electrochemical Studies of Paracetamoland Folic Acid in the Presence of Epinephrineat Poly (Eosin) Modified Electrode: A Voltammetric Study

“…amino} benzoyl]-L-glutamic acid, often regarded as a part of vitamin B complex, possesses the considerable biological importance for general human health, especially during periods of rapid cell division and growth [25,26]. Deficiency of folic acid is a common cause of anaemia and it is thought to increase the likelihood of heart attack and stroke.…”
