• tissue have been observed [22]. Liposome encapsulation of SN38 (LE-SN38) enhances the solubility of SN38 and provides protection from rapid drug degradation. Increased cytotoxicity against various tumor cell lines and better therapeutic efficacy in xenograft mouse models, as compared to CPT-11, have been

• reaction with ZnO to form amorphous Zn(CO)3, which roughens the surface of the nanowires [12]. Therefore, for practical application the device encapsulation is essential to ensure a clean oxygen atmosphere around the nanowires. In this work we investigate the performance of polymer-embedded ZnO nanowires

This, in consequence, enables the preparation of copolymer particles of defined composition and the encapsulation of further, monomer soluble materials [4]. For the preparation of inorganic, ceramic materials
