Progress of Enzymatic and Non-Enzymatic Electrochemical Glucose Biosensor Based on Nanomaterial-Modified Electrode

“…The main restriction of non-enzymatic glucose biosensors is specificity. Recently, scholars reported high-sensitivity non-enzymatic glucose biosensors based on the modification of electrodes with metal [ 38 , 39 ], metal oxide [ 17 , 40 ], and composite nanomaterials [ 19 , 21 , 41 ].…”

“…The main restriction of non-enzymati biosensors is specificity. Recently, scholars reported high-sensitivity non-enzym cose biosensors based on the modification of electrodes with metal [38,39], me [17,40], and composite nanomaterials [19,21,41]. Most of the review papers that have been published covered the recent deve of enzymatic and nonenzymatic glucose biosensors, and mainly focus on the fa strategies and significance of the nanomaterials towards the electrochemical perf of the glucose biosensors [33,[42][43][44].…”

Preparation of MoS2@AuNP nanocomposite by a self-reduction method and its application for electrochemical glucose sensing

“…12 AuNPs can also accelerate the rate of electron transfer and are widely used as electrode modification materials in the field of electrochemistry. 13,14 Nanocomposites consisting of MoS 2 and AuNPs exhibit superior chemical and physical properties compared with single nanomaterials. 15 For example, Lin and co-workers developed a cholesterol sensor with excellent performance based on MoS 2 and AuNPs.…”

Thermoplastic Starch and Graphite Biocomposite Electrode for Electrochemical Catechol Sensor

“…24,25 The differential of this work regarding the development of the biocomposite is the use of a biodegradable material, of low cost and high availability, such as starch. Other studies report a similar methodology, 18,20,26 however the biopolymers used are expensive 18,20 when compared to starch, in addition they use solvents such as acetone 26 and chloroform, 18 which are more toxic than the dimethyl sulfoxide (DMSO) used in this research. Thus, composite of TPS and graphite (TPS-Gr), was produced and z E-mail: marystela@ufscar.br…”

“…This type of composite, which combines polymeric materials with carbonaceous conductive materials, is already widespread in the literature, and has been applied in the manufacture of electrochemical sensors. [18][19][20] Among the main reasons for the commercial productive advance are the characteristics obtained, such as good mechanical, thermal and electrical properties. In addition, it is worth noting the low cost compared to commercial sensors and the fact that in some cases the polymers used in production are fully biodegradable, enabling the development of efficient and ecologically correct disposable sensors.…”
