(A) Scanning electron microscopy images of (1) felt/CSCNTs/graphene oxide material, (2) felt/CSCNTs/graphene oxide image at higher magnification, and (3) CSCNT/RGO-coated fibers and the corresponding voltammograms in the presence of immobilized GOx in 20 mmol L−1 PBS and 0.1 mol L−1 KCl. Reproduced from [120], with permission from Elsevier. (B) (4–9) Micrographs of carbon fibers and carbon nanoblisters generated through chemical processing and (10) the electrochemical response to glucose. Reprinted (adapted) from [126], with permission from Elsevier. (C) (11) Fabrication and mechanical tests of a 3D CNT-agarose hydrogel composite for (12) application in skin-based wearable biosensors. Reprinted (adapted) from [127] with permission from the American Chemical Society. (D) (13) SEM micrographs of the mesoporous carbon matrix with high carbon nanoparticle loading employed as the working electrode for BOD immobilization, (14) cyclic voltammogram of MvBOD-modified electrode in (red line) O2-saturated electrolyte performing the ORR and (black line) Ar saturated demonstrating no process for the bioelectrocatalysis of ORR. Reprinted (adapted) from [128], with permission from Nature. (E) (15–17) SEM micrograph of a graphene oxide/poly(N-isopropylacrylamide) porous formed after a polymerization time with the (18) electrochemical signals from redox probes in the external medium before and after sequential thermal opening of the polymeric brushes gate, operating in a smart-sensing thermal stimulus-activated electrochemical sensor.
