Dopamine/mucin-1 functionalized electro-active carbon nanotubes as a probe for direct competitive electrochemical immunosensing of breast cancer biomarker

MUC1: Structure, Function, and Clinic Application in Epithelial Cancers

“…Directly competitive electrochemical immunosensors based on gelatin modifications of dopamine (DA)/MUC1-functionalized electroactive carbon nanotubes have also been designed to be used as signal generation probes for the early diagnosis of breast cancer. The gelatin-modified electrodes were used as supports to immobilize antibodies (anti-MUC-1), and the electrochemical reactions of functionalized electroactive carbon nanoprobes were used for the quantitative measurement of MUC-1 [ 83 ]. New radiolabeled conjugates and peptides with desirable biological properties have also been used to target tumor-specific MUC1 antigens to diagnose and treat cancers [ 84 ].…”

Nickel -doped iron oxide nanoparticle-conjugated porphyrin interface (porphyrin/Fe2O3@Ni) for the non-enzymatic detection of dopamine from lacrimal fluid

“…In the Nyquist plots, the semicircle diameter at higher frequencies and a linear portion at lower frequency corresponded to the electron transfer resistance ( R et ) and diffusion-limited mechanism, respectively. 46 The resistance of bare GPE in Fig. 2B(a) decreased after Fe 2 O 3 deposition as revealed in Fig.…”

Functionalized thiazolidone-decorated lanthanum-doped copper oxide: novel heterocyclic sea sponge morphology for the efficient detection of dopamine

“…The obtained semicircle diameter at higher frequencies in the Nyquist plots corresponds to the electron transfer resistance ( R et ) and linear portions at a lower frequency parallel to the diffusion-limited mechanism, respectively. 41 The resistance of the bare GPE electrode R ct = 228 Ω ( Fig. 2B(a) ) decreased to R ct = 146 Ω after fabrication with CuO ( Fig.…”
