Cells are strongly influenced by the local structure and mechanics of the extracellular matrix (ECM). We recently showed that adding agarose to soft collagen ECMs can mechanically stiffen these… Expand
One-step modification of superhydrophobic surfaces by a mussel-inspired polymer coating.
A bio-inspired approach for superhydrophobic surface modification was investigated. Hydrophilic conversion of the superhydrophobic surface was easily achieved through this method, and the… Expand

We demonstrate the effects of protein orientation and trehalose on a quantitative analysis of surface-immobilized proteins by using time-of-flight secondary ion mass spectrometry (TOF-SIMS). As our… Expand
Label-free calcium imaging in ischemic retinal tissue by TOF-SIMS.
The distribution and movement of elemental ions in biologic tissues is critical for many cellular processes. In contrast to chemical techniques for imaging the intracellular distribution of ions,… Expand
Quantitative ToF-SIMS study of surface-immobilized streptavidin
ToF-SIMS analysis with principal component analysis (PCA) has been used for quantitatively studying the interaction between streptavidin and biotin on a dendrimer surface. A poly(amidoamine)… Expand
ToF-SIMS study on the cleaning methods of Au surface and their effects on the reproducibility of self-assembled monolayers
Abstract The production of reproducible self-assembled monolayers (SAMs) is essential to many nano(bio)technology applications. To check the effects of different cleaning methods on a reproducible… Expand
Chemical derivatization technique in ToF-SIMS for quantification analysis of surface amine groups
Abstract A chemical derivatization technique in ToF-SIMS along with principal component analysis (PCA) were used to perform a quantitative study of the surface amine density of the plasma-polymerized… Expand
Characterization of PEG‐conjugated gold nanoparticles using a statistical analysis on time‐of‐flight SIMS images
Gold nanoparticles (AuNPs) and poly(ethylene glycol) (PEG) are known to be safe, biocompatible materials. In this study, AuNPs were conjugated with PEG ligands, and the suspensions of AuNPs with and… Expand
Bioinspired, cytocompatible mineralization of silica-titania composites: thermoprotective nanoshell formation for individual chlorella cells.
Hard-shell case: Using a (RKK)4 D8 peptide allows mineralization to occur under cytocompatible conditions. Thus individual Chlorella cells could be encapsulated within a SiO2 -TiO2 nanoshell with… Expand
Biomimetic micropatterning of silica by surface-initiated polymerization and microcontact printing.
Micropatterns of silica on a gold substrate were generated by a biomimetic approach, namely, the biosilicification of silicic acids. The procedure consists of three simple steps: pattern generation… Expand
