One-pot preparation of hydrophilic citric acid-magnetic nanoparticles for identification of glycopeptides in human saliva.

A facile and mild approach was carried out to synthesize citrate acid-magnetic ferroferric oxide for glycopeptide analysis. The material was synthesized successfully and applied in glycopeptide identification from human saliva, indicating that this method could be a promising tool for glycopeptidome analysis, which also enlightened the simple fabrication of hydrophilic materials in analytical science.
