Conjugates of organometallic osmium carbonyl clusters and gold nanoparticles (see picture) show a strong carbonyl signal in surface-enhanced Raman spectroscopy. The ease of bio-functionalization and the high stability and good dispersibility in aqueous solution make these conjugates excellent candid...
