Transparent and flexible glucose biosensor via layer-by-layer assembly of multi-wall carbon nanotubes and glucose oxidase

Amperometric glucose sensor based on glucose oxidase immobilized on gelatin-multiwalled carbon nanotube modified glassy carbon electrode

“…The sensitivity value at the composite film is 2.47 μA mM −1 cm − 2 for glucose. In Table 1, the electroanalytical values observed at the GCNT/GOx/GAD composite film in this work are comparatively presented with other GOx modified electrodes reported previously [19,[26][27][28][29][30]. From Table 1 it is clear that GCNT/GOx/GAD composite film possesses good linear range (6.30-20.09 mM) for glucose which is significantly higher than the linear range obtained at other GOx modified electrodes (see Table 1).…”

Polymer/clay and polymer/carbon nanotube hybrid organic–inorganic multilayered composites made by sequential layering of nanometer scale films

“…Detection targets of SWNT LBL composites are only limited by our imagination. Biological materials such as DNA [140], glucose [124,125,129,[141][142][143][144][145][146], dopamine [147,148], uric acid [147], and toxic materials such as arsenic [149], phenols [125] were often detected by amperometric measurements of CNT LBL nanocomposites utilizing the combinations of electrocatalytic activities, electrochemical sensitivities of CNTs, and various materials immobilization given by versatile selections of LBL assembly. Environmental changes like humidity are easily monitored by CNT LBL composites [150].…”

Enzyme-Encapsulated Layer-by-Layer Assemblies: Current Status and Challenges Toward Ultimate Nanodevices

“…[215] Negatively charged MWNTs and GOD were LbL assembled on the polymer substrate modified by Au. The film showed a porous structure where the assembled MWNTs were mainly in the form of individual tubes or small bundles.…”
