The present invention relates to the field of pharmaceutical preparations, in particular, to a mannose modified targeting nano-preparations, a composition for preparing nano-preparations, a targeting element, a targeting vector, a prepared targeting drug and a preparation method and the application thereof. The described nano-preparations with targeting function is composed of the targeting ligand mannose and its derivatives, nano-preparations and main drug components, and the described targeting material is linked with the spacer material, and then linked with the nano-preparations material to prepare the nano-preparations. The targeting nano-preparations in the present invention has good targetability of mannose receptor, can effectively bond with mannose receptor on target cell. Moreover, the preparation method has universality, can be used for synthesizing a variety of targeting nano-preparations, and is conducive to purification and characterization.
