A novel nano-interfaced superoxide biosensor

The Importance of ATP-related Compounds for the Freshness and Flavor of Post-mortem Fish and Shellfish Muscle: A Review

“…They used distilled water or phosphate buffer (pH 8.2) to extract ATP-related compounds (Lawal and Adeloju, 2012;Nanjyo and Yao, 2002;Thandavan et al, 2013;Devi et al, 2013). A heating process has also been introduced to extract ATP-related compounds.…”

“…Hx by itself has been widely used as a freshness indicator in fish (Jones et al, 1964;Lawal and Adeloju, 2012;Spinelli et al, 1964). Most recently, measurements of Hx have become a promising freshness indicator using both amperometric and potentiometric biosensors (Lawal and Adeloju, 2012;Thandavan et al, 2013).…”

Anamperometric superoxide anion radicalbiosensor based on SOD/PtPd-PDARGO modified electrode

“…• À could be estimated by UV spectrophotometry [10]. The stock solution of O 2 • À is determined to be 40 mM.…”

“…However, these methods cost much and usually occupy too much space. Recently, enzyme-based electrochemical sensors [9][10][11][12][13][14] appear to be a hotspot for determining O 2 • À , because they can provide desired analytical performance with high reliability, sensitivity and selectivity as well as the preparation simplicity and capability in terms of direct and real-time detection. With the ability to catalyze the dismutation of O 2 • À to O 2 and H 2 O 2 (employed as a biomarker) through a cyclic oxidation-reduction electron-transfer mechanism [15], copper, zinc-superoxide dismutase(Cu, Zn-SOD) is the most widely used enzyme to be immobilized onto the electrode surface to fabricate the electrochemical O 2 • À biosensor [16].…”

An improved non-enzymatic hydrogen peroxide sensor based on europium functionalized inorganic hybrid material—Evaluation of optical and electrochemical properties

“…[21][22][23]. Among all these techniques, electrochemical methods have attained more interest due to its high sensitivity, simple handling, low operating expense, rapid output and its ecofriendliness when compared with the other strategies [24][25][26][27][28][29]. http To date, there are some reports employing electrochemical technique based on FeMoO 4 , copper, iron-silver core-shell structure, or graphene-silver hybrid as sensing materials for detecting hydrogen peroxide.…”
