| Abstract | In this paper, several amphiphilic oligomers were synthesized using a low molecular weight polymaleianhydride and different aliphatic alcohols. Water-soluble Au/Ag noble nanocrystals (NCs) were thenprepared by an organic-aqueous phase transfer method with appropriate amphiphilic oligomers basedon surface-bound interactions. The obtained water-soluble Au/Ag NCs have the same visible color andUV–vis spectra as those formed initially in organic solvent.We found that hydrophobic ester chain lengthof the amphiphilic oligomer can dramatically affect the phase transfer efficiency,whichwas explained bythe impact of local hydrophobic environment on the stability of NCs in water. A biocompatible test alsoshowed that the water-soluble Au/Ag NCs were very stable in various physiological conditions withouparticle aggregation. |
