In this work, researchers from Thin-film and Nanostructure electrodeposition Group (GE-CPN) have developed an electrochemical procedure for the preparation) of hydroxyapatite (HAP) micro/nanostructures for applications in drug delivery, biosensors and in some bone regeneration. Hydroxyapatite (HAP) has been extensively used as a bioactive ceramic due to its biocompatibility and biodegradability and a wide range of research is ongoing to prepare micro/nanostructured HAP. The main objective of this work has been develop a new and straightforward method for the electrochemical fabrication of HAP on FTO (Fluorine-doped Tin Oxide) in a new electrolyte solution containing calcium and phosphate precursors, along with sodium nitrate and hydrogen peroxide. Compared to the metallic substrates, transparency, corrosion resistance and stability of FTO under biology media cause an increase in its applications as a biocompatible substrate.
