title: Superparamagnetic nanocrystal clusters for enrichment of low-abundance peptides and proteins.
abstract: Clusters of densely packed hydrophobic superparamagnetic gamma-Fe(2)O(3) nanocrystals have been developed as a powerful adsorbent for enrichment of peptides and proteins, with advantages such as high enrichment efficiency, fast processing, easy magnetic separation, and direct mass analysis.
