Abstract
Water-soluble ssDNA-encapsulated Ag clusters exhibit large two-photon cross sections reaching 50 000 GM, with high quantum yields in the red and near-IR. Three distinct, spectrally pure, several atom clusters emitting at 660, 680, or 710 nm have been created with two-photon cross sections rivaling those of much larger water-soluble semiconductor quantum dots. Their stability, biocompatibility, and small size offer the promise of nontoxic, sensitive high-resolution biological imaging.
