While high-throughput, robust, and highly sensitive mass spectrometry (MS) analysis is essential for proteomic breakthroughs, current ion sources often grapple with achieving all three simultaneously. Existing options might provide good sensitivity but require complex emitter setups and meticulous maintenance, limiting accessibility. Conversely, user-friendly alternatives may compromise sensitivity, hindering deep proteome coverage. A groundbreaking nanoESI ion source disrupts this status quo by integrating advanced sensors and "plug & play" nanoelectrospray emitters. These emitters boast an ultra-sharp cone angle and a hydrophobic silica nanoparticle coating, significantly improving electrospray ionization for increased sensitivity and reduced sample consumption. The "plug & play" design eliminates complex emitter setups, making high-performance emitters accessible to all researchers. Integrated sensors continuously monitor critical conditions, ensuring optimal performance and safeguarding instruments. This system was tested using the Direct Infusion Shotgun Proteomics Analysis (DISPA) approach on a Thermo Fisher Scientific Orbitrap Astral mass spectrometer, achieved remarkable results: identifying approximately 2,000 proteins from HeLa cells at a rate exceeding 8 proteins per second, along with detecting a broad spectrum of biomarkers in human plasma samples. This innovative approach, combining unmatched sensitivity and robustness with user-friendly operation, paves the way for significant advancements in clinical diagnostics and biomarker discovery, transforming the clinical landscape.
