Scholarcy highlights
- Hydroxyapatite–gelatin composites have been proposed as suitable scaffolds for bone and dentin tissue regeneration
- An existing process used to coat a surface with hydroxyapatite under near physiological conditions, the alternate soaking process, is modified and automated using an inexpensive “off the shelf” robotics kit
- Samples were investigated by Fourier transform infrared spectroscopy, scanning electron microscopy, energy dispersive X-ray spectroscopy and nanoindentation
- Calcium phosphate coatings formed by the alternate soaking process exhibited different calcium to phosphate ratios, with correspondingly distinct structural morphologies
- Hydroxyapatite–gelatin composite coatings over 2 mm thick could be formed with little visible porosity
- The hydroxyapatite–gelatin composites demonstrate a composition and mechanical properties similar to those of cortical bone
