Orthopedic issues affect millions of people due to factors such as aging, diseases like osteoporosis, and accidental injuries. The materials commonly used for interbody fusion cages can be categorized into metallic and non-metallic types. The most frequently used interbody cages are made from non-absorbent materials, such as titanium (Ti) and poly-ether-ether-ketone (PEEK). However, titan…
Due to its circular material properties, Eggshell waste offers excellent potential for reuse in various industries. We aim to promote sustainability in biomedical applications by effectively using these materials. The project involves extracting powders from eggshells (ES) and eggshell membranes (ESM) and treating them with bactericidal metal oxides, such as gallium oxide, using magnetron…
According to the World Health Organization, back-pain was among the top ten diseases causing the greatest burden in 2019. It is estimated that 30 to 40% of these cases are attributed to intervertebral disc (IVD) degeneration. Currently, there are no satisfactory treatments for IVD degeneration, if analgesics and physical therapy fail to control the pain, the discs are removed and replaced…
The major challenge in developing materials for biomedical applications is to obtain a material with excellent volume and surface properties. When inserted into the human body these materials should exhibit a good response and interaction with the medium. Studies about surface topography show that TiO2 nanotubes can improve the cell adhesion. The development of this research over the year…

In the field of biomaterials, infections related to prostheses and biomedical implants remain a significant challenge, despite advancements in research. One approach to reduce bacterial colonization is to modify the surfaces of permanent implants or to incorporate metallic bactericidal agents into biodegradable implants. Gallium, a metal known for its antibacterial properties, shows promi…
The fabrication process of ceramic scaffolds using an extrusion-based additivemanufacturing technique is known as direct ink writing or robocasting Robocasting is anadditive manufacturing technique that involves the direct extrusion of colloidalsystems. This process consists of computer-controlled deposition of a highlyconcentrated suspension, such as ceramic paste, layer by layer through…
According to the World Health Organization, back pain was among the top ten diseases that caused the greatest onus on society in terms of years lived with disability in 2019. An estimated 30 to 40% of these cases are attributed to intervertebral disc (IVD) degeneration. There are currently no intensive treatments for IVD degeneration. If analgesics and physical therapy fail to control the…

The biodegradable metals are a new alternative for implantable materials whose functions in the body are temporary. The iron-based alloys present high mechanical resistance and high ductility making their use feasible in the manufacture of stents for example, but they present a very slow degradation rate. To improve the degradation rate and their mechanical proprieties it is necessary to …
The purpose of this study is the surface modification of Ti7.5Mo experimental alloy by using TiO2 nanotubes growth associated to incorporation of calcium and phosphate. The Ti7.5Mo alloy will be obtained in arc melting furnace with argon inert atmosphere and processing by heat treatment. The anodic oxidation will be carried out to obtain TiO2 nanotubes growth in electrolyte in order to pr…
The purpose of this study is the grafting of Ti7.5Mo alloy after TiO2 nanotubes growth. Ti7.5Mo alloy will be processed in arc melting furnace with argon atmosphere. Anodic oxidation will be carried out to obtain TiO2 nanotubes on the Ti7.5Mo alloy surface. Subsequently, bioactive polymers bearing sulfonate [styrene sodium sulfonate (NaSS)] will be deposited by radical polymerization at 7…

The major challenge of the materials for biomedical applications is to obtain a material with excellent bulk and surface properties. When inserted in the human body they must exhibit a good interaction and response. Studies about surface topography showed that TiO2 nanotubes improved the cellular adhesion. Roughness surfaces are beneficial for osseointegration and bone anchorage; however,…
