Streptococcus agalactiae and Staphylococcus aureus are two pathogenetic agents of several infective diseases in humans. Biocidal effects and cellular internalization of ZnO nanoparticles (NPs) on two bacteria are reported, and ZnO NPs have a good bacteriostasis effect. ZnO NPs were synthesized in the EG aqueous system through the hydrolysis of ionic Zn2+(More)
Monodispersed single crystalline alpha-GaOOH rods coated by silk fibroin (SF) have been prepared via a facile biomineralization process in the template of SF peptide. The carbon-coated alpha-Ga(2)O(3) and beta-Ga(2)O(3) rods are obtained by thermal treatment of the alpha-GaOOH rods at 600 and 800 degrees C, respectively. In vitro cytotoxicity studies of(More)
Peptides are emerging as pharmaceutical agents in cancer therapy. The peptide, TLSGAFELSRDK (TLS) is a targeting ligand that can specifically triggers cellular uptake by binding to SKOV3 cells. Cell surface proteins and the C-terminal basic residues of the TLS are required for effective cell penetration, and the uptake process is energy-dependent. It(More)
Discovery of peptide ligands that can target human ovarian cancer and deliver chemotherapeutics offers new opportunity for cancer therapy. The advent of phage-displayed peptide library facilitated the screening of such peptides. In vivo screening that set in a microanatomic and functional context was applied in our study, and a novel peptide WSGPGVWGASVK(More)
To develop more biomarkers for diagnosis and therapy of ovarian cancer, a 12-mer phage display library was used to isolate peptides that bound specifically to the human ovarian tumor cell line SK-OV-3. After five rounds of in vitro screening, the recovery rate of phages showed a 69-fold increase over the first round of washings and a group of phage clones(More)
To combine the advantages of different electrolytes in anodic oxidation, pure titanium samples were anodized in CH(3) COOH electrolyte according to a novel anodizing treatment regime and then in H(2) SO(4) electrolyte in potentialstatic mode. The in vitro bioactivity of the as-prepared titanium samples was evaluated by simulated body fluid (SBF) test. In(More)
Zinc oxide nanoparticles (NPs) with the size of ∼100 nm were prepared via a facile biomineralization process in the template of silk fibroin (SF) peptide at room temperature. These ZnO NPs have shown the remarkable behavior of low toxicity to gram-positive bacteria (Staphylococcus aureus, Staphylococcus agalactiae), gram-negative bacteria (Escherichia(More)
In this work, hierarchical ZnO particles were prepared using a biomineralization strategy at room temperature in the presence of peptides acidified from spider silk proteins. A mechanism of the mineralization of the ZnO particles was that the affinity of original ZnO nanoparticles and zinc ions in the peptide chains played an important role in controlling(More)
In this paper, olive-like ZnO particles were successfully synthesized via a facile biomineralization process in the template of silk fibroin (SF) peptide at room temperature. The coat of SF peptide on the surface of ZnO particles had a substantial influence on their morphology during the biomineralization. Room-temperature photoluminescence behavior of ZnO(More)
Surface-porous titanium samples were prepared by anodic oxidation in H(2)SO(4), H(3)PO(4) and CH(3)COOH electrolytes under various electrochemical conditions. X-ray diffraction (XRD), scanning electron microscopy (SEM) and energy dispersive X-ray spectroscopy (EDX) were employed to characterize the structure, morphology and chemical composition of the(More)
