Highly-selective electrochemical determination of catechol based on 3-aminophenylboronic acid-3,4,9,10-perylene tetracarboxylic acid functionalized carbon nanotubes modified electrode

Electrochemical Sensing Platforms of Dihydroxybenzene: Part 1 – Carbon Nanotubes, Graphene, and their Derivatives

“…It plays a significant role in different biological phenomena such as the flower‐stimulating effect and also acts as an antioxidant and anticancer agent. It also affects enzyme activities [17–19] . Besides these properties, CTs function as typical neurotransmitters that affect the regulation of blood pressure and metabolic processes, and its concentration in different body fluids is used as an index for certain diseases such as hypertension, phaeochromocytoma, neuroblastoma septic shock, Parkinson's disease, and pharmacological vasodilatation [20] .…”

“…Besides these properties, CTs function as typical neurotransmitters that affect the regulation of blood pressure and metabolic processes, and its concentration in different body fluids is used as an index for certain diseases such as hypertension, phaeochromocytoma, neuroblastoma septic shock, Parkinson's disease, and pharmacological vasodilatation [20] . CTs exist in different natural sources such as fruits, teas, vegetables, and some traditional Chinese medicines (TCM) [21] and are used as raw materials in various applications, such as photography, perfumes, fur dyes, lubricating oils, antifungal preservatives in potato plantations, synthetic materials, and insecticide production [17,22] . They are also commonly used as a rubber hardener in manufacturing, electroplating additive, skin antiseptic, and building block in organic synthesis [23,24] .…”

Construction of amperometric biosensor modified with conducting polymer/carbon dots for the analysis of catechol

“…Between the phenolic compounds, Catechol (1, 2-hydroxybenzene or 1, 2benzenediol), is found in many everyday products, such as cosmetics, pesticides, pharmaceuticals and food additives. 1 It has been classified as a periodic toxic pollutant. The US Environmental Protection Agency (US EPA) and the European Commission (EC) have created a list and special attention has been devoted to catechol because of its low degradation rate and high toxicity.…”

“…Identification and quantification of phenolic compounds have received exceptional interest from the scientific community owing to their high toxicity in nature, water resources and human health. Between the phenolic compounds, Catechol (1, 2‐ hydroxybenzene or 1, 2‐ benzenediol), is found in many everyday products, such as cosmetics, pesticides, pharmaceuticals and food additives 1 . It has been classified as a periodic toxic pollutant.…”

Highly Sensitive and Simultaneous Detection of Hydroquinone and Catechol Using Poly(mercaptoacetic acid)/Exfoliated Graphene Composite Film‐modified Electrode

“…Hydroquinone (HQ) and catechol (CC) are two significant isomers of phenolic compounds being widely used in many fields, such as medicines, cosmetics, pesticides and photography 1. Unfortunately, the two isomers are highly toxic to both environment and human even at very low concentrations and are difficult to degrade in the ecological environment 2. In the past few decades, various analytical methods have been established for the simultaneous determination of HQ and CC such as liquid chromatography 3, synchronous fluorescence technique 4, chemiluminescence 5, spectrophotometry 6 and electrochemical methods 7.…”
