Thaxton, C. S. et al. Nanoparticle-based bio-barcode assay redefines “undetectable” PSA and biochemical recurrence after radical prostatectomy. Proc. Natl Acad. Sci. USA 106, 18437–18442 (2009).

Researchers at Northwestern University have developed and piloted an ultrasensitive, automated immunoassay that is capable of detecting serum PSA at concentrations as low as 330 fg/ml—approximately 300 times more sensitive than commercially available immunoassays.
