This study benchmarks sub-50 nm quartz nanopipette emitters for native electrospray ionization mass spectrometry across multiple platforms and protein sizes, showing improved signal-to-noise and reduced adduction.

This paper introduces Nuc-MS, a method to directly analyze chromatin reader-nucleosome interactions by disassembling complexes and identifying histone proteoforms involved in binding.

This paper introduces a correlative imaging method using nano-DESI MSI to map lipids, metabolites, peptides, and proteins in single tissue sections, revealing molecular gradients in mouse pancreatic tissue.
