Application of Fe3O4 mesoporous sphere modified carbon ionic liquid electrode as electrochemical hemoglobin biosensor

Mesoporous Materials‐Based Electrochemical Enzymatic Biosensors

“…Mesoporous materials applied to electrochemical biosensors can be classified in three main categories, silica‐based materials 97–137, carbon‐based materials 113, 138–178, 76, 179–184 and metal oxides other than silica 121, 130, 185, 73, 186–198, 75, 74, 199–202. A mesoporous polymer, i.e., polyacrylamide, was also namely reported 203, but in this latter example, the organic template was kept in the membrane and no information on the porosity was given.…”

“…Oxide materials other than silica that have been applied to electrochemical biosensing are mesoporous Nb 2 O 5 185, 73, 199, Al 2 O 3 188, SnO 2 191, 193 and doped SnO 2 , i.e., antimony‐doped tin oxide (ATO) 75 and indium‐doped tin oxide (ITO) 192, 195, ZrO 2 194, 74, ZnO 201, TiO 2 186, 190, 191, 196, 200, MnO 2 189, 197, or Fe 3 O 4 121, 198. Hydroxyapatite was also used 196, 202.…”

“…Carbon paste electrodes 118, 146, 168, 198 and screen printed electrodes 113, 125, 126, or cavity microelectrode 149, are other electrode configurations that are popular in electroanalysis and that have been applied for the development of enzymatic biosensors with mesoporous materials. In such case, the mesoporous material bearing the enzyme was simply incorporated as dry powder in the composite carbon paste or ink matrix (or accommodated to the cavity electrode).…”

Release of Insulin from Calcium Carbonate Microspheres with and without Layer-by-Layer Thin Coatings

“…Organic and inorganic nano-and micro-particles have been extensively studied for the development of catalysts, biosensors, reagents for imaging, and drug delivery systems [1][2][3][4][5][6][7][8]. CaCO 3 microspheres are widely used owing to their facile preparation, biocompatibility, and low cost [9][10][11].…”

Sensitive electrochemical detection of bisphenol A with chitosan and urchinlike MnO2microsphere modified carbon ionic liquid electrode

“…It has been proved that CILE exhibits some excellent characteristics such as easy preparation, anti-fouling ability and good electrocatalytic activity [30,31]. Our group applied different kinds of CILE for electrochemical sensors [32,33]. Safavi et al studied the direct electrochemistry of haemoglobin on the CILE surface [34].…”
