The advantages of protein identification by nanopore peptide profiling are numerous. Unlike some traditional methods, nanopore sensing often requires no labeling, offering a more streamlined workflow. Furthermore, it boasts high sensitivity, fast detection speed, real-time monitoring, and simple operation, according to recent studies. This makes it particularly promising for applications requiring rapid analysis, such as direct detection of pathogen-derived proteins and peptides from clinical samples.

The process typically involves preparing protein samples, which may include digestion into peptides if a peptide-based approach is employed. Proteins are digested into peptides, and then these individual peptides are analyzed as they pass through the nanopore. This is akin to peptide mass fingerprinting, a traditional approach for protein identification often used with mass spectrometry, but achieved through a different detection mechanism. The resulting data provides a unique protein fingerprint.Polypeptide analysis for nanopore-based protein ...
