Abstract The study aimed to fabricate and evaluate a bone tissue engineering scaffold made from a composite of polylactic-co-glycolic acid (PLGA). nano-hydroxyapatite (nHA). and graphene oxide (GO) using low-temperature 3D printing and freeze-drying techniques. The scaffolds were produced with varying compositions: PLGA alone and in combination with nHA and GO. https://cuttingedgecutleryco.shop/product-category/fire-starter/
