Electrochemical Tracing of Butein Using Carbon Nanoparticles Interfaced Electrode Processed from Biowaste

Abstract

Nanoparticles of carbon derivatized from pyrolysis of biowaste oil palm leaves were processed as electrochemical transducer material at the interface of glassy carbon electrode. This modified electrode exhibits convincing electron‐transfer property for voltammetric and chronoamperometric quantification of clinically important phytochemical, butein, without the use of external redox mediator and enzyme. A reversible two‐electron transfer redox property observed from butein is distinct at the electrode interface and the current density is found to be superior in phosphate buffered saline electrolyte at pH 7.0. Carbon nanoparticles interfaced electrode system displayed a good stability and sensitivity for butein with a detection limit of 7.6 μM and a dynamic detection concentration ranging from 10 to 100 μM. This bio‐waste translated carbon nanoparticle represent a promising electrode material for various flavonoids detection useful for biological studies.

β-Cyclodextrin-Tethered Butein, a Greener Redox-Active Biomaterial for Electrochemical Enzymatic Sensing of Sialic Acid

“…The Δ E p of the BCD-Bt system was found to be 0.94 V, suggesting the transformation of the quasi-reversible redox behavior of Bt into reversible upon conjugation with BCD. The conversion of ortho dihydroxy groups into ortho quinone in the BCD-Bt implies the two-electron and two-proton reaction at the interface . To reveal the reversibility of the prepared conjugated system at the electrode interface, a scan rate dependence study was performed (Figure B).…”

“…The conversion of ortho dihydroxy groups into ortho quinone in the BCD-Bt implies the two-electron and two-proton reaction at the interface. 34 To reveal the reversibility of the prepared conjugated system at the electrode interface, a scan rate dependence study was performed (Figure 3B). The corresponding linearity of the peak current is illustrated in Figure 3C, enabling a coefficient of determination value R 2 = 0.99, suggesting the surfaceconfined process at the electrode−electrolyte interface.…”

Comparative investigation of bioflavonoid electrocatalysis in 1D, 2D, and 3D carbon nanomaterials for simultaneous detection of naringin and hesperidin in fruits

“…10 From this viewpoint, electrocatalysis involving interfacial electron transfer at electrodes can be employed for rapid bioavonoid determination. 11 Indeed, several studies on the electrochemical detection of bioavonoids have been reported, especially using electrodes functionalized with different nanomaterials, such as gold nanocage, 12 gold nanoparticles, 13 carbon nanotubes, 14 graphene oxides, 15 carbon nanoparticles 16 and their combinations. [17][18][19][20] For example, Sebastian et al reported a amine-functionalized multi-walled carbon nanotube (CNT) and 3D rose ower-like zinc oxide nanocomposite for electrochemical detection of morin.…”

Unique Host Matrix to Disperse Pd Nanoparticles for Electrochemical Sensing of Morin: Sustainable Engineering Approach

“…Such novel carbon materials can be considered for various practical applications. Different methods exist in the literature for the synthesis of carbon nanospheres. − The method employed here to synthesize CNSs is eco-friendly without the usage of any catalysts and cost-effective . In the present research work, CNSs have been synthesized by a catalyst-free pyrolysis technique from the leaves of Mimosa pudica , a perennial flowering plant well-known for its nyctinastic foliar movement.…”
