Water-dispersible hydrophilic fluoridated HAp:Ln(3+) (Ln = Eu or Tb) nanoparticles were prepared via hydrophobic/hydrophilic transformation with surfactants (Pluronic F127). The HAp:Ln(3+) (Ln = Eu or Tb) nanoparticles with unique luminescent properties and excellent biocompatibility are promising for cell imaging applications.

Highly selective sensing of cytidine triphosphate (CTP) against other triphosphate nucleosides including ATP, GTP and UTP is successfully achieved with a luminescent terbium(III)-organic framework (TbOF) of [Tb(2)(2,3-pzdc)(2)(ox)(H(2)O)(2)](n) (2,3-pzdc(2-) = 2,3-pyrazinedicarboxylate, ox(2-) = oxalate).
