Interface-controlled calcium phosphate mineralization: effect of oligo(aspartic acid)-rich interfaces

Abstract

The phase behavior of an amphiphilic block copolymer based on a poly(aspartic acid) hydrophilic block and a poly(n-butyl acrylate) hydrophobic block was investigated at the air–water and air–buffer interface.

A Dendritic Amphiphile for Efficient Control of Biomimetic Calcium Phosphate Mineralization

“…The film was compressed to 40 mN m −1 , and after 1–2 min, a 3 m phosphate solution was injected beneath the monolayer. For comparison with previous data mineralization was performed at 20 °C using 2 × 10 −3 m subphases. Moreover, the mineralization conditions were expanded to also include subphases with 20 and 200 × 10 −3 m and reaction times of 3, 4, and 5 h.…”

“…Due to the fact that we mineralize CP just beneath an amphiphile monolayer this layer is much thinner (only a few nm thick) than bulk samples. In order to avoid superposition of P 2p with and Si plasmon signals (see an example in ref …”

Facile synthesis of scandium fluoride oriented single-crystalline rods and urchin-like structures by a gas–solution interface technique

“…30 The F 1s peak centered at 686.3 eV may be attributed to the metal-fluorine bonds. 31 According to the XPS analysis, the Sc/F ratio is close to 24/76 which conforms to the nominal composition of ScF 3 .…”

“…5b; only Sc and F were detected. The resulting average ratio of Sc/F is 23/77 which corresponds to stoichiometric ScF 3 .…”

“…Usually, surface-active molecules assist in this process. For example, mineralization with the assistance of an amphiphilic block copolymer 3 and silk fibroinmediated biomineralization 4 were carried out at the air-water interface. Alternatively, isothermal evaporation can be applied to fabrication of organic crystals by a drop-casting method at the air-liquid interface.…”
