The microstructure of bone consists of nano-hydroxyapatite (nano-HA) crystals aligned within the interspaces of collagen fibrils. To emulate this unique microstructure of bone. this work applied two biomimetic techniques to obtain bone-like microstructures in vitro. that is. https://www.roneverhart.com/SAAB-9-3-I-98-02-Frontlykt-Hoyre/
