Colon cancer can occur as small, non-cancerous cell masses called polyps that form in the lining of the colon. Targeted cancer therapy is a method in which substances or drugs are used to target cancer cells without affecting normal cells. This method often uses nanoparticles. Among the nanoparticles that are of great importance are carbon nanotubes, which have many applications in medicine...
Breast cancer is one of the most common cancers among Iranian women, and 7,000 women are diagnosed with this cancer annually. Currently, this technology is used in various medical fields, but one of the most important areas of nanomedicine is related to cancer treatment, because it has had very positive effects on it so far. Iron and manganese oxide nanoparticles are particles in the size...
Carbon-based nanomaterials are emerging as key modifiers in 3D bioprinting due to their electrical, surface, and biochemical properties. They enhance shear-thinning, print fidelity, and mechanical strength by forming conductive polymer–nanomaterial networks. They also influence ionic flux, Ca²⁺ dynamics, and redox conditions through controlled ROS generation, supporting signaling pathways...
By incorporating functional and stimuli-responsive nanoparticles, passive bioprinted scaffolds can be transformed into controllable and adaptive material systems. Such particles impart chemical, electrical, magnetic, and light-responsive behavior while reinforcing polymer networks and improving rheology. These nanoparticles create nanoscale domains that convert external stimuli into localized...
In recent years, considerable attention has been directed toward exploring alternative materials for screws used in jawbone tissue replacement. Nevertheless, issues related to the cytotoxicity and biocompatibility of these materials remain subjects of ongoing debate. In this study, we developed a novel implant for jawbone tissue regeneration by depositing a titanium carbonitride (TiCN) film...

This study aims to analyze the effect of the lateral movement mechanism occurring during the chewing movement on the pure titanium material-based implant body using the Finite Element Analysis (FEA) method. In this study, a pure titanium-based dental implant material designed to international standards was subjected to 0.5 mm lateral movement mechanisms under a 70 N bite force. The force...
Biomaterials are extensively employed in medical implants owing to their remarkable biocompatibility and resistance to corrosion. These materials offer a robust foundation for various coating applications, among which hydroxyapatite is particularly notable due to its close chemical similarity to natural bone tissue, ensuring superior biocompatibility. A wide array of materials is currently...
This study aims to design and manufacture a Programmable Logic Controller (PLC) controlled wear device with high accuracy and precision that can simultaneously move in two axes through the wear process. Within the scope of the study, synchronous step motors that can provide lateral and vertical axis motion drive and a PLC controller that can provide real-time control were used through the wear...
Commercially pure titanium is often preferred in biomedical applications due to their high biocompatibility behaviour. However, the inadequate wear, fatigue and corrosion resistance of titanium limit their use as a biomaterial in the human body. The purpose of the present study was to investigate contact- and contact-free wear resistance and hardness of titanium for biomedical applications. In...
