Title
Biological oxygen sensing via two-photon absorption by an ir(III) complex using a femtosecond fiber laser
Abstract
Near-infrared two-photon absorption of the phosphorescent Ir(III) complex (2,4-pentanedionato-κO2,κO4)bis[2-(6-phenanthridinyl-κN)benzo[b]thien-3-yl-κC]iridium (BTPHSA) was characterized. It exhibited a 800–1200 nm two-photon absorption band, and thus could be electronically excited by 1030-nm femtosecond Ti:sapphire and Yb-doped fiber lasers. By using BTPHSA, oxygen concentrations in human embryonic kidney 293 (HEK293) cells were imaged. These results demonstrate two-photon oxygen sensing of live tissues via easily operable excitation sources.
