This project aims to create a 316L stainless steel coated with a biocomposite based on chitosan for use in the biomedical industry. To completely coat the material, the dip-coating technique was used to apply plain chitosan, chitosan nanosilver, chitosan biotin, and chitosan-nanosilver-biotin in that order. This coating’s surface morphology was investigated with field emission scanning electron microscopy (FESEM). Surface roughness, average size distribution, and 2D and 3D surface tomography were all investigated using scanning probe microscopy and atomic force microscopy (SPM and AFM). The Fourier transform infrared (FTIR) spectroscopy technique was used to quantify changes in functional groups. To evaluate the coated samples’ wettability, contact angle measurements were also performed. The chitosan (CS) + nanosilver, CS + biotin, and CS + biotin + nanosilver-coated 316L stainless steel showed roughness values of about 8.68, 4.21, and 3.3 nm, respectively, compared with the neat chitosan coating, which exhibits 12 nm roughness, indicating a strong effect of biotin and nanosilver on surface topography whereas the coating layers were homogenous, measuring around 33 nm in thickness. For CS + nanosilver and CS + biotin, the average size of agglomerates was approximately 444 nm and 355 nm, respectively. The coatings showed adequate wettability for biomedical applications, were homogeneous, and had no cracks. Their contact angles were around 51–75 degrees. All of these results point to the composite coating’s intriguing potential for use in biological applications.

“…Despite the aforementioned characteristics, synthetic HA has limited use as a bone graft material due to several problems, including achieving the optimum crystallinity level, phase purity, low mechanical properties, and high in vitro solubility [5,6]. To solve these problems, extensive research is being conducted to produce HA metal composite or ion substituted/HA using various techniques [7][8][9]. Ionic substitution has emerged as a powerful technique for enhancing the performance of HA, either by modifying its structural, morphological, and chemical characteristics or by leveraging the substituting ions' therapeutic effects [10,11].…”

Cancerous diseases and diseases resulting from bacteria and fungi are some of the pressures that humans face. Therefore, the development of biomaterials that are resistant to cancerous diseases, bacteria, and fungi has become one of the requirements of the medical field to extend the life of the biomaterial and fight pathogens after implanting these materials inside the human body. One of the important biomaterials used in the field of orthopedics is hydroxyapatite. In this research, Nano substituted hydroxyapatite was prepared by the wet precipitation method, including replacing 5% of the calcium ions with neodymium, cerium, magnesium, and zinc ions in cationic substitution. Many tests were carried out to characterize the prepared material. The biological properties were evaluated by examining the resistance of the substituted hydroxyapatite to bacteria and fungi, in addition to testing the effect of the material on normal cells and bone cancer cells. The results showed a new structure of hydroxyapatite after the substitution process and a significant improvement in the biological properties of the prepared biomaterial compared to other researches.
