Electrochemical Biosensors for Detection of MicroRNA as a Cancer Biomarker: Pros and Cons

“…The probe-DNA immobilization and the miRNA hybridization steps were supervised by EIS measurements in [Ru(NH 3 ) 6 ] 3+/2+ . The proposed biosensor allowed reaching an LOD of 0.034 pM, and the analysis of miRNA-21 levels in human lung cancer cells [179].…”

Phase transformations in the nickel phosphide system induced by transition-metal doping and their electro-catalytic study

“…𝐸 × 3600 𝑡 (5) Where: P is power density in kW/kg, E is energy in Wh/kg and t is the discharge time in s.…”

“…Transition metal phosphides, in particular nickel phosphides, are of interest to materials scientists due to their applications in energy storage, 1–3 energy generation, 4 bio-sensing 5 and catalytic recycling. 6 Reports on nickel phosphides are limited compared to the sulfide analogs because their preparation is constrained by factors such as toxicity, prolonged reaction times, elevated temperatures and multiple starting precursors.…”

Thioredoxin Reductase-Mediated Reaction Evokes In Situ Surface Polarization Effect on BiOIO3: Toward a New Sensing Strategy for Cathodic Photoelectrochemistry

“…Under optimal detection conditions (Figure S8), the photocurrent intensity was enhanced with increased TrxR concentrations from 0.007 to 0.5 μM, which showed a good linear relationship between the photocurrent response and logarithm of TrxR concentration (shown in Figure 4C,D). The linear equation was ΔI = 227.7 log[TrxR] + 529.7 (R 2 = 0.991), and the detection limit (calculated according to the signal-to-noise ratio of 3, that is, S/N = 3, in which "S" means the detected signal and "N" represents the standard deviation of 10 blank assays 31 ) obtained was 2.0 nM. Compared to the few reported fluorescence assays for TrxR, 14−17 the split-type PEC method proposed in this work exhibited superior detection performance in terms of sensitivity (Table S1) and was more simple and rapid to operate, without involving a complicated enzyme substrate synthesis process.…”
