Abstract

This study aimed to enhance the biocompatibility and corrosion resistance of commercially pure titanium substrate using the most modern deposition technique utilized for biomedical applications, Electrostatic Spray Deposition (ESD). To construct the bio composite-polymer base coating, different percent’s (2, 6, and 10) wt.% of Hydroxyapatite (HAP), Nickel Oxide (NiO), and Niobium Oxide (Nb2O5) powder were combined with (98, 94, and 90) wt.% of polymethyl methacrylate (PMMA) powder coating. And, the hybrid coatings groups were constructed by combining different percents of (NiO with HAP) and (Nb2O5 with HAP) with 90 wt.% of PMMA. The FESEM, EDS mapping, XRD, FTIR, contact angle, and anti-bacterial tests demonstrated that the coating layer was consistent, crack-free, hydrophilic, and had good inhibition of bacterial growth. While the in vitro experiments prove that in simulated body fluid for 30 days at 37°C, the coating layers exhibited a significant capacity for forming apatite crystals on their surfaces indicating high osseoconductivity and the immersion test showed high corrosion resistance. Also, Vickers microhardness and scratch hardness showed that the ceramics particles improve the polymeric coating hardness and adhesion.

Abstract:

This research aims to manufacture two types of contact lenses (hard and soft), study the effect of adding aloe vera gel on the composition and properties and know the effect of covering the lenses with a thin layer of colloidal silver. A hard lens was prepared from poly methyl methacrylate and a soft lens was prepared by polymerization of many monomers to form a hydrogel. Samples were mixed with different weight percentages of aloe vera gel. Several tests were performed on the resulting lenses before and after adding aloe vera gel and also before and after covering them with colloidal silver. All samples showed great resistance to Staphylococcus aureus, and the effect of aloe vera was strongly observed. Adding aloe vera gel to contact lenses helps enhance their performance, as the degree of homogeneity is very high.
