In this paper, we demonstrated a simple and highly sensitive fluorescence platform for protein detection.
Importantly, these NCQDs are demonstrated to be excellent ECL luminophor for protein detection due to their stable emission, well dispersibility, low toxicity and good compatibility with biomolecules.
Based on fluorescence quenching between guanine bases and fluorophore, a cost-effective biosensor for protein detection is developed.
This novel ECL strategy provides a simple, economical, fast and sensitive approach for multiplexed immunoassay of CEA and CA199, and has significant potential for protein detection in a clinical laboratory setting.
In this work we have developed a peptide-based method for protein detection, termed as "Recognition-induced Covalent Capturing and Labeling" (RCCL).
Through the cascade amplification of SDA and DE-RCA, the sensitivity was further improved with a detection limit of 3.8 × 10−16 mol/L for protein detection.
Next, an investigation of the role of thin films of gold, silver, and aluminum for protein detection in SPR biosensors is presented.
Altogether, our results indicate that the E/K coiled coil system is a good alternative for protein detection by Western blot.
The biosensor exhibits excellent analytical performance for protein detection in a range from 41.7 nM to 4.17 μM, with a detection limit of 4.17 nM.
In this work, we have proposed a label-free nanopore-based biosensing strategy for protein detection by performing the DNA protein interaction inside a single glass conical nanopore.
In this work, a new sensing scheme for protein detection is presented based on converting liquid-phase colorimetric assay into enhanced surface-tethered electrochemical analysis.
