AB  - We report the first example of very efficient NIR Circularly Polarized 
      Luminescence (CPL) (around 970 nm) in water, obtained thanks to the combined use 
      of a chiral Yb complex and of poly lactic-co-glycolic acid (PLGA) nanoparticles. 
      [YbL(tta)(2) ]CH(3) COO (L=N, N'-bis(2-pyridylmethylidene)-1,2-(R,R+S,S) 
      cyclohexanediamine and tta=2-thenoyltrifluoroacetonate) shows good CPL in organic 
      solvents, because the tta ligands efficiently sensitize Yb NIR luminescence and 
      the readily prepared chiral ligand L endows the complex with the necessary 
      dissymmetry. PLGA nanoparticles incorporate the complex and protect the metal ion 
      from the intrusion of solvent molecules, while ensuring biocompatibility, water 
      solubility and stability to the complex. Hydrophilic NIR-CPL optical probes can 
      find applications in the field of NIR-CPL bio-assays.
