Defective Prussian Blue Analogue with Cobalt for Fabrication of An Electrochemical Sensor for Detecting Ascorbic Acid, Dopamine and Uric Acid

“…[27][28][29] Therefore, the accurately simultaneous detection of AA, DA and UA in biological fluids is helpful for clinical diagnosis. Among the sensing materials, carbon materials with low toxicity and excellent conductivity were commonly used as modifier to improve the electrochemical performance of the sensor, including carbon nanotubes, [30] functionalized porous carbon, [31,32] graphenes such as reduced graphene oxide [33] and N-doped graphenes, [34,35] which are beneficial to the simultaneous determination of AA, DA and UA. To enrich the active sites and the catalytic activity, the noble metal nanoparticles [36,37] and some transition metals were incorporated in the modified layer, such as FeÀ Mn compound, [38] CoFe alloy, [39] especially cobalt, which was commonly act as the catalytic center to facilitate electrochemical redox of AA, DA and UA for the improvement of sensitivity.…”

Nitrogen Doped Porous Biochar/β-CD-MOFs Heterostructures: Bi-Functional Material for Highly Sensitive Electrochemical Detection and Removal of Acetaminophen

“…It is also reported that doping of N in the carbon skeleton could break the inertness of sp3 hybridized C and create abundant defects and effective active sites, which greatly improves the conductivity and catalytic performance of carbon material [ 15 ]. For example, Huang et al developed an enhanced electrochemical platform based on lotus leaves and derived N,P-doped porous carbon nanoparticles for the determination of ascorbic acid with a low limit of detection (LOD) (4.25 μM) [ 16 ]. Zou et al synthesized nitrogen self-doped porous carbon derived from a cicada shell for electrochemical determination of Cu 2+ with a relatively low LOD of 25.24 nM [ 17 ].…”

3D Biomass‐Derived Carbon Materials for Electrochemical Biosensors

“…In recent years, as a member of the carbon family, BC, especially 3D-BC structures, has received increasing attention from researchers. Compared to other carbon-based electrode modification materials such as graphene and carbon nanotubes, BC is designed and obtained from natural biomaterials, which reduces the cost of sensor preparation and creates great economic [27,28,[37][38][39][40][41][42] The performance improvement diagrams of BC-based materials in b) DA, [16,24,[43][44][45][46][47][48][49] c) Pt 2+ , [38,41,[50][51][52][53][54][55][56] and d) H 2 O 2 [23][24][25]28,[57][58][59][60][61] in recent years. e) Comparison of the sensing performance of BC-based modified materials for DA, Pt 2+ , and AP.…”

“…We compiled a timeline of the development of BC electrode modification materials, which provides a good overview of the progress reported each year (Figure 1a).
