中文摘要positive charged silica nanoparticles, entrapping hydrophobic photosensitizer 2,9,16, 23-tetraamino-phthalocyanine zinc (znpc(nh(2))(4)), have been synthesized in the nonpolar core of micelles by hydrolysis of triethoxyvinylsilane (tevs) and 3-aminopropyltriethoxysilane (aptes). the water-soluble, stability, surface morphologies and charge were characterized using transmission electron microscopy (tem), dynamic light scattering (dls) and uv-visible spectrophotometer. the as-prepared nanoparticles are highly monodispersed spheres with uniform diameter (about 20 nm), and stable in aqueous system. its average potential value is 28. 8 +/- 2. 79 mv and exhibits strong absorption peak at 714 nm. in addition, encapsulation of znpc(nh(2))(4), in the silica nanoparticles prevented znpc (nh(2))(4) from leaking and enhanced the anti-photobleaching. the znpc (nh(2))(4) entrapped-nanoparticles (sio(2)@znpc(nh(2))(4)) can efficiently generat singlet oxygen as measured by chemical probe 1,3-diphenylisobenzofuran (dpbf). the toxicity of silica nanoparticles to cells has been investigated by the incubation of the znpc(nh(2))(4), entrapped-nanoparticles and the nanoparticles without znpc(nh(2))(4)(sio(2)-nh(2)) with living cancer cells (hela, u251, pc-12). the experimental result reveals that both sio(2)@znpc(nh(2))(4) and sio(2)-nh(2) particles have no significant toxicity when the concentration of the particles is below 300 mg/l.
