The electrochemical enzymatic glucose biosensor based on mesoporous carbon fibers activated by potassium carbonate

Recent Trends on Electrochemical Sensors Based on Ordered Mesoporous Carbon

“…They can serve as hosts for the biomolecules and associated cofactors and mediators, and the abundant interconnected pores in the OMC can facilitate mass transport and offer large accessible surface area for reactants and electrons. The various biosensing applications involving OMC materials [ 194 , 195 , 196 , 197 , 198 , 199 , 200 , 201 , 202 , 203 , 204 , 205 , 206 , 207 , 208 , 209 , 210 , 211 , 212 , 213 , 214 , 215 , 216 , 217 , 218 , 219 , 220 , 221 , 222 , 223 , 224 , 225 , 226 , 227 , 228 , 229 , 230 , 231 , 232 , 233 , 234 , 235 , 236 , 237 , 238 , 239 , 240 , 241 , 242 , 243 , …”

“…From a comparative study [ 263 ], it was even claimed that OMC shows enhanced electrocatalytic features in comparison to graphene, as explained by different microstructures in these materials, although graphene-based electrochemical sensors and biosensors are now well-established [ 264 , 265 , 266 ]. OMC materials with hierarchical pore structures and/or large mesopores [ 214 , 220 , 221 , 222 , 223 , 226 , 231 ] seem to be the most promising ones (ensuring high enzyme loadings and fast transport of reagents). Graphitized or partially graphitic mesoporous carbons are also attractive because of their high conductivity [ 200 , 232 ].…”

Evaluación de la capacidad de almacenamiento de energía en xerogeles de carbono activados obtenidos a partir lignina

“…La estructura final de los geles de carbono se obtiene luego del secado (subcrítico, supercrítico o criogénico), y posterior carbonización y/o activación (física o química) con el fin de aumentar el área superficial, y también se pueden incorporar heteroátomos tales como oxígeno, nitrógeno y/o fósforo, que puedan promover efectos pseudocapacitivos originados por propiedades de electrón aceptor/donador [24]. La activación química es la más utilizada debido a que se alcanzan áreas superficiales específicas mayores a 1000m 2 /g donde los agentes activantes más comunes son KOH [25][26][27][28][29], K 2 CO 3 [30][31][32][33], ZnCl 2 [30,34,35] y H 3 PO 4 [30,[36][37][38][39][40][41][42]. El KOH como agente activante tiende a producir una estructura más microporosa con poros anchos, el K 2 CO 3 ha sido utilizado recientemente por ser ambientalmente amigable y seguro, el ZnCl 2 es un agente que tiende un mayor desarrollo mesoporoso y el H 3 PO 4 proporciona una distribución de poros más heterogénea con posibilidad de inclusión de heteroátomos de fósforo y es de fácil recuperación [40,43].…”

Non-enzymatic detection of glucose in fruits using TiO2–Mn3O4 hybrid nano interface

“…The blood glucose level in normal person ranges between 70 and 80 mg dL -1 (Gao et al 2015;Heli and Amirizadeh 2016). The increase in the amount of glucose in blood results in type 1 and type 2 diabetes (Kim et al 2015;Hsu et al 2016;Li et al 2016). The consumption of fruits raises blood glucose levels in diabetic patients, which in-turn leads to various complications including peripheral, vascular, ocular and cardiac diseases (Ameen et al 2016;Chou et al 2016).…”

“…The concentration of glucose in blood serum of patients with type I and type II diabetes can be calculated from the current density of enzymatically released H 2 O 2 (Xia et al 2014;Kim et al 2015;Zhang et al 2016). Compared to electrochemical glucose oxidase enzyme-based biosensors, non-enzymatic glucose biosensors based on metal oxide nanoparticles offer good stability against denaturation, easy to fabricate and facilitate effective glucose oxidase enzyme like catalysis over a wide temperature and pH ranges (Eguílaz et al 2015;Heli and Amirizadeh 2016;Li et al 2016).…”
