A wide range of polymeric scaffolds have been intensively studied for use as implantable and temporal devices in tissue engineering. Biodegradable and biocompatible scaffolds having a highly open porous structure and good mechanical strength are needed to provide an optimal microenvironment for cell proliferation, migration, and differentiation, and(More)
Cationic lipid-coated gold nanoparticles were developed for efficient intracellular delivery of therapeutic siRNA. Particle formation was characterized by UV-visible spectroscopy, atomic force microscopy, and dynamic light scattering analysis. Cellular uptake, gene silencing effect, and cytotoxicity were investigated in multiple human cancer cell lines.(More)
Since computed tomography (CT) was developed and its resolution, sensitivity, and scan speed rapidly improved, the use of CT in the diagnosis of hepatic disease has been evaluated by various investigators. [1] In particular, liver-specific X-ray CT imaging has attracted much attention in cancer diagnosis and cancer treatment because liver metastases are a(More)
By using short linear antimicrobial peptides as a model system, the effect of peptide charge on the specificity between Candida albicans (fungi) and Gram-positive bacteria was investigated. In a present study, we added and/or deleted lysine residue(s) at the C-terminal and/or N-terminal end(s) of an antimicrobial peptide (KKVVFKVKFK-NH(2)) and synthesized(More)
Layer-by-layer (LbL) assembly has attracted much attention because of its ability to create multifunctional films on surfaces while maintaining bulk properties. [1] The method relies on sequential adsorption of polymers onto bulk surfaces from solution, giving rise to complex multilayered films. LbL assembly is simple to implement and offers extensive(More)
Composites of polymers and nanoparticles have received much attention due to their enhanced optical and electronic properties relative to pure polymeric materials. 1 Spatial control of nanoparticles in different poly-meric domains is of great interest for practical applications such as solar cells, 2 photonic crystals, 3 and high density magnetic storage(More)
A precise control of metallic-nanoparticle assembly is highly critical for the realization of tangible, high-performance devices or materials. Until recently, nanoparticle assembly using 1D templates had been limited to a narrow spectrum of nanoparticles as it was mostly dependent on the surface chemistry of the nanoparticles used. Inspired by the universal(More)
