英文摘要：

Nanoparticles prepared by multi-functional water-soluble polymer ligands with monodispersity in the small size range possess numerous excellent physical properties, such as hiocompatibility, near infrared fluorescence, superparamagnetism, etc. , which are better than those prepared by traditional methods. The paper reviews the recent progress of preparations for noble metal nanoparticles, magnetic nanoparticles, quantum dots and core-shell complex nanoparticles, studies the advantages of multi-functional water-soluble polymer ligands and analyzes the effects of various factors on preparing of nanoparticles, for example, structures, molecular weight and the concentration of multi-functional water-soluble polymer. Finally, the paper discusses the versatile emerging applications of nano-size, monodisperse and water-soluble nanoparticles in the field of ligand exchange, targeted drugs delivery system, disease detection, bio-labels, magnetic resonance imaging （MRI） and optoelectronies. Simultaneously, the considerable research orientation of preparing nanoparticles with multi-functional water-soluble polymer ligands is propected.
