Polyaniline (PANI) nanotubes were synthesized separately using amino acetic acid (AA), ethylenediamine tetraacetic acid (EDTA), oxalic acid (OA) as dopant and ammonium persulfate (APS) as oxidant by a self-assembly method. SEM, TEM,FTIR and X-ray diffraction (XRD) and applying the 4 probes method characterized the morphology, structure and property of the product. It was found that nanotubes morphology were synthesized when the [Aci/[A ratio is 1:2.The room template conductivity of the products were studied.

The hydrogen-bonding multilayered polyelectrolyte capsules with sizes around 6 μm were fabricated by layer-by-layer self-assembly method. The morphology of the obtained capsules was observed with Scanning Electron Microscope (SEM), Confocal Laser Scanning Microscope (CLSM) and Atomic Force Microscope (AFM), respectively. The elastic properties of the capsules were studied with AFM. The capsule was pressed by cantilever with different lengths, a glass bead glued at the end of the cantilever. The force curves were measured on the capsule in air. The Young's modulus of the capsule was obtained (E = 170 MPa for the loading). Results show that this model can predict the elastic deformation of the microcapsule. The accuracy of the elastic deformation of polymer capsule can be ensured using a cantilever of mediate stiffness. Our results show that the existence of the hydrogen-bonding layer makes the multilayered polyelectrolyte harder in comparison with the pure multilayered polyelectrolyte capsules.

The modulatory effect of miR-21 on the proliferation of melanoma cells through stimulation of PTEN (Phosphatase and tensin homologue deleted on chromosome 10) expression was investigated in the current study. PTEN, as a tumor suppressor, is expressed in low levels in melanoma tissues and cell lines. Nevertheless, miR-21 can stimulate cancer development and suppress cell apoptosis. Overexpression of PTEN substantially impaired the proliferation of miR-21-treated melanoma cells. In addition, miR-21 and PTEN were observed to exhibit a combinatorial effect, whereas miR-21 could negatively regulate the expression of PTEN. In conclusion, these findings demonstrate that miR-21 affects melanoma development by targeting PTEN, establishing a new strategy for treating malignant melanoma. Furthermore, in this study, microparticles and nanoparticles were employed as carriers to construct, through the self-assembly method, nanocapsules carrying miR-21 in order to develop an efficient nanocapsule delivery system of miR-21 against melanoma cells.
