title: Near-infrared in vivo bioimaging using a molecular upconversion probe.
abstract: We demonstrate molecular upconversion probe, NRh-1, which shows excellent photostability, high quantum yield up to 1.8%, and rapid excretion capability. The NIR-to-NIR upconversion technique offers remarkably improved signal-to-noise ratios and substantially higher tissue penetration depth.
