Bio-inspired calcium phosphate mineralization through enzymatic approach, Minéralisation de phosphate de calcium d'inspiration biologique par approche enzymatique

Jihye Lee

Biomineralization of calcium phosphate (CaP) is the process by which some organism builds hard mineralized tissues, such as bone, enamel and calcified cartilage. This process is regulated through various physicochemical factors and biochemical reactions, involving particularly matrix vesicles (MVs…, La biominéralisation du phosphate de calcium (CaP) est le processus par lequel un organisme construit des tissus minéralisés durs, tels que l'os, l'émail et le cartilage calcifié. Ce processus est régulé par divers facteurs physico-chimiques et réactions biochimiques, impliquant en…

Aerosol-assisted self-assembly of hybrid Layered Double Hydroxide particles into spherical architectures

Vanessa Prevot, Claire Szczepaniak, Maguy Jaber

Acetate intercalated NiAl-Layered Double Hydroxide nanoparticles were prepd. by polyol process and further used as building blocks to form hybrid LDH spheres by a spray drying technique. The spherical aggregated LDH particles display a polydispersed size with a diam. ranging from 47 nm to 2 μm.…
