Europium (III) (Eu3+)-doped hydroxyapatite (HAp) nanocrystals were synthesized in the presence of a cetyltrimethylammonium bromide (CTAB) to investigate the states of Eu3+ ions in the structure. The HAp structure was preserved with the doping as well as the CTAB existence, and the carbonate ions were included in the structure. The uniform shapes and mono-dispersion of the nanocrystals were observed...
Shape-memory surfaces with on demand, tunable nano-patterns have been developed to observe time dependent changes in fibroblast cell alignment using temperature-responsive poly(ε-caprolactone) (PCL) films. The PCL films were prepared by crosslinking tetra-branched and linear PCLs, each with acrylate end-groups. Permanent surface patterns were generated by crosslinking the PCLs in a mold. Temporary...
