Abstract

We created a local microenvironment for biomineralization by using gel particles. Nanometer-sized and spiral-shaped mineral was produced from the surface of particle aggregates. Also, their pitch and width were controllable by the size of gel particles.

Highlights

  • We created a local microenvironment for biomineralization by using gel particles

  • We previously reported on mineralization using gel particles in which calcium ions were incorporated prior to mineralization

  • PHEMA gel particle, which is similar to the particle used in our previous study as described above,[18] was prepared by dispersion polymerization of 2-hydroxyethyl methacrylate (HEMA) and methylenebisacryl-amide (MBAAm)

Summary

Introduction

Nanometer-sized and spiral-shaped mineral was produced from the surface of particle aggregates. Their pitch and width were controllable by the size of gel particles. It is thought that Brownian motion is reduced and thereby a laminar ow and a convective current are suppressed inside the gels, making the diffusion dominant for the mass transport in gel media. This would cause a modi cation to the crystal growth regimes and numerous studies have been. Communication gel particles were alternately immersed in 500 mL of 50 mM Ca(NO3)[2] aqueous solution and 500 mL of 100 mM Na2CO3 aqueous solution (solvent displacement method), followed by an incubation at 70 C for 24 h
