Magnetite–graphene for the direct electrochemistry of hemoglobin and its biosensing application

Polyhedral Magnetite Nanocrystals with Multiple Facets: Facile Synthesis, Structural Modelling, Magnetic Properties and Application for High Capacity Lithium Storage

“…They have broad applications in biology and biomedicine, including drug delivery and targeting, [7][8][9][10][11][12] immunoassays, [13] hyperthermia, [14] magnetic resonance imaging contrast enhancements, [15] biosensing, [16] and the separation, purification or detection of proteins, DNA, viruses, and cells, etc. [17][18][19][20] For biological applications, many researchers have prepared Fe 3 O 4 magnetic nanoparticles with various structures, or loaded them with silica, [21] polymer, [22] and lipid vesicles, [23] etc. Furthermore, magnetite nanoparticles have been applied as electrode materials in supercapacitors, [24][25][26] and lithium ion batteries (LIBs).…”

Direct electrochemistry of hemoglobin on graphene/Fe3O4 nanocomposite-modified glass carbon electrode and its sensitive detection for hydrogen peroxide

“…Based on these properties, GE has shown great potential applications in electronic devices [2], energy conversion and storage [3], and biosensors [4]. However, GE is limited to designing biosensors for its hydrophobicity and agglomerate in water [5,6]. Therefore, the combination of GE with other functional materials may result in the composition integrating characterizations and functions of each component.…”

Electrochemical Behaviors of Glucose Oxidase Based on Biocatalytic Deposition of Gold Nanoparticles

“…9 New materials with good biocompatibility to improve behaviors of biosensors have aroused great interests among analysts in this field. Carbon nanomaterials (CNMs) have been widely applied in the construction of biosensors and electroanalytical investigations [10][11][12][13] because of their good stability, relatively wide potential window, low background current, high catalytic properties, highly loading of biocatalysts, unique structural and excellent electrical conductivity. [14][15][16][17] The novel morphology monkshoodvine root-bark like carbon (MLC) has been successfully controllablly synthesized by our group.…”
