Studies on Processing and Characterization of Hydroxyapatite Biomaterials from Different Bio Wastes

Abstract

Development of suitable materials that acts as an interface between the implant and tissues in body system structurally, mechanically and bio functionally is important for the success of tissue engineering. This motivated materials scientists and biologists to find out suitable bioactive materials for the aforementioned purpose. There has been growing interest in developing bioactive synthetic ceramics that could closely mimic natural apatite characteristics. Hydroxyapatite (HAp) has been widely used as a biocompatible ceramic but mainly for contact with bone tissue, due to its resemblance to mineral bone. This study presents the synthesis and characterization of HAp materials from different sources like bovine bone and fish scales and their application in tissue engineering. The phase purity and crystallinity of different calcined HAp powder was determined by XRD and FTIR analysis. The Thermo Gravimetric and Differential Thermal Analysis were carried out to show the thermal stability of the HAp powder. The morphology of the powder was observed under Scanning Electron Microscopy (SEM). Cytotoxicity evaluation of the developed powder was carried out in RAW macrophage like cell line media for an incubation period of 72 hours. These results proved the biocompatibility of HAp powders obtained from different biosources for tissue engineering applications.

Tailoring the adsorption behavior of bone char for heavy metal removal from aqueous solution

“…The stretching vibration of the OH À groups corresponds to the signal at $3430 cm À1 (Mondal et al, 2012;Rojas-Mayorga et al, 2013). The asymmetric stretching vibration mode of PO 3À 4 group is given by the signal at $1030 cm À1 , while the P-O bending vibration mode corresponds to the bands at 960 and 605 cm À1 (Mondal et al, 2012;Rojas-Mayorga et al, 2013).…”

Fabricación de filamentos de PCL y PVA reforzados con HAp para ser usados en impresión 3D

“…El fosfato de calcio [Ca10(PO4)6(OH)2] o hidroxiapatita, es especialmente utilizado como material de injerto óseo en aplicaciones médicas y dentales, debido a su gran similitud con la composición natural de los huesos [12], [13]. La HAp es biocompatible y bioactiva, sin embargo presenta malas propiedades mecánicas.…”

Characterization and Utilization of Calcium Oxide (CaO) Thermally Decomposed from Fish Bones as a Catalyst in the Production of Biodiesel from Waste Cooking Oil

“…Other additional benefits can be added, which include their abundance and cheap feedstock. Many studies have reported the mechanism of fish bones thermal decomposition [10][11]. The fish bones were decomposed into calcium oxide at various temperatures before being used as a catalyst in the production of biodiesel from waste cooking oil.…”
