“…C60 is a truncated icosahedron made out of five and six member rings of sp 2 carbons, which plays an important role in the family of nanocarbons [8]. C60 has a broad range of charming properties, such as high electronic conductivity, large specific surface area, good biocompatibility, inert behavior, stable structure and good adsorption capacity towards organic molecules [9][10][11].…”

“…In this context, carbon nanomaterials have attracted great interest because of the structural differences in their various allotropes (e.g., graphite, fullerene, carbon nanotubes (CNT), graphene, diamond, diamond-like carbon (DLC)) (see Figure 1) and their wide variety of structurally dependent electronic and electrochemical properties [2]. Carbon nanomaterials cover a broad range of structures: zero-dimensional (fullerenes, diamond clusters), one-dimensional (nanotubes), two-dimensional (graphene), and three-dimensional (nanocrystalline diamond, fullerite) structures [3].…”

Nanotechnology is becoming increasingly important in the field of (bio)sensors. The performance and sensitivity of electrochemical biosensors can be greatly improved by the integration of nanomaterials into their construction. In this sense, carbon nanomaterials have been widely used for preparation of biosensors due to their ability to enhance electron-transfer kinetics, high surface-to-volume ratios, and biocompatibility. Fullerenes are a very promising family of carbon nanomaterials and have attracted great interest in recent years in the design of novel biosensing systems due to fullerenes' exceptional properties. These include multiple redox states, stability in many redox forms, easy functionalization and signal mediation. This paper outlines the state-of-the-art and future directions in the use and functionalization of fullerene-C 60 and its derivatives, both as electrode modifiers and advanced labels in electrochemical catalytic and affinity biosensors through selected applications.

“…[1][2][3][4][5][6][7] In addition, the electrochemical activation of carbon surfaces has been used for applications including electroanalytical chemistry and electrocatalysis. [8][9][10] Recently, it has been revealed that nitrogen atoms containing functional groups can be easily introduced onto the surfaces of glassy carbon (GC) electrodes by the electrode oxidation of ammonium carbamate in an aqueous medium at a highly positive electrode potential.…”

“…12 Carbon materials are widely used in electroanalysis due to their considerable electrocatalytic activity. 13 Possessing high specific surface area and excellent electrical conductivity, MWCNTs have been widely employed for the construction of electrochemical sensors to improve analytical responses. 14 However, in addition to the limitations of high cost and the ease of forming aggregates, the lack of defect sites of MWCNTs will result in poor electrochemical performance.…”

Graphite nanosheets prepared by thermal expansion and successive sonication were utilized for the construction of a multi-walled carbon nanotubes/graphite nanosheets based amperometric sensing platform to simultaneously determine acetaminophen and dopamine in the presence of ascorbic acid in physiological conditions. The synergistic effect of multiwalled carbon nanotubes and graphite nanosheets catalyzed the electrooxidation of acetaminophen and dopamine, leading to a remarkable potential difference up to 200 mV. The as-prepared modified electrode exhibited linear responses to acetaminophen and dopamine in the concentration ranges of 2.0 × 10 -6 -2.4 × 10 -4 M (R = 0.999) and 2.0 × 10 -6 -2.0 × 10 -4 M (R = 0.998), respectively. The detection limits were down to 2.3 × 10 -7 M for acetaminophen and 3.5 × 10 -7 M for dopamine (S/N = 3). Based on the simple preparation and prominent electrochemical properties, the obtained multiwalled carbon nanotubes/graphite nanosheets modified electrode would be a good candidate for the determination of acetaminophen and dopamine without the interference of ascorbic acid.
