title: Nanoscale metal-organic frameworks as highly sensitive luminescent sensors for Fe²⁺ in aqueous solution and living cells.
abstract: We report the exploration of fluorescent nanoscale metal-organic frameworks (nMOF-253s) for highly selective and sensitive detection of Fe(2+) ions in aqueous solution. Moreover, nMOF-253 of 50 nm is successfully applied in fluorescent bioimaging and intracellular Fe(2+) sensing in HeLa cells.
