Biomimetic Growth and Self‐Assembly of Fluorapatite Aggregates by Diffusion into Denatured Collagen Matrices

Abstract

Elongated, hexagonal-prismatic seed crystals are the starting point for the hierarchical growth of anisotropic spherical aggregates of fluorapatite in gelatin matrices. Discrete dumbbell-shaped aggregates (scanning electron microscope image shown on the right) are formed by self-similar, branched, needlelike upgrowths at both ends of the seeds. With successive generations, these aggregates close to give pheres with diameters of up to 400 μm. The system makes it possible to monitor the development of antibiotic information pattern into the macroscopic range

Co-precipitation of silica and alkaline-earth carbonates using TEOS as silica source

“…These clusters are composed of radially aligned crystals. Similar shapes have been reported for other composite structures such as fluoroapatite-collagen aggregates [24]. Simultaneously, micron-sized particles consisting of witherite nanorods in parallel arrangement were generated in the reaction cells (Fig.…”

Shape Controlled Synthesis of Barium Carbonate Microclusters and Nanocrystallites using Natural Polysachharide – Gum Acacia

“…In the present work, it is believed that the functional groups in GA control the formation of BaCO 3 clusters by adsorbing onto certain facets of BaCO 3 crystals. However, it has to be pointed out that the exact growth mechanism is still unknown, although some explanation was given in the literature based on the role of intrinsic electric fields which direct the growth of dipole crystals [45][46][47].…”

Crystal Splitting in the Growth of Bi2S3

“…For example, Kniep et al [28] investigated the biomimetic growth of fluorapatite in gelatin matrices and found that starting with hexagonal prismatic seed crystals, dumbbell-shaped aggregates of fluorapatite grow and eventually form closed spheres.…”
