Biomaterials are a fundamental topic in biomedical engineering, and they are materials and devices that interact safely and effectively with body tissue.<br />They are products designed to become embedded in the body over time after their performance, without the need for surgical removal.<br /><br />Examples of Use:<br />• Surgery (sutures): In addition to after wound healing.<br />• Stents: Benign tumors in blood vessels, which then dissolve after remaining partially open.<br />• Drug Carriers: Release film and then fail.<br /><br />Key Materials Used:<br />• Polylactic Acid (PLA)<br />• Polygalactic Acid (PGA)<br />• Modified Cellulose<br />Improved Biocompatibility (Biocompatibility):<br />The remarkable ability of a material to interact with the body without causing rejection, inflammation, or toxicity.<br /><br />Why is it Important?<br /><br />It must: Because any material implanted in the body<br />• Does not cause organogenesis.<br />• Does not cause action or toxicity.<br />• They work naturally with vascular tissue (such as not inhibiting bone or blood vessel healing).<br /><br />Methods to improve compatibility:<br />• Modifying the surface of the material (such as increasing wear or adding a protein layer).<br />• Using materials that are closer to the natural composition of tissue, such as hydroxyapatite for bone.<br />• Adding nanomaterials or antibacterials for infection.<br />Spare materials (nanomaterials for drug delivery)<br />Very small particles or systems (usually between 1-100 coulombs) for drug delivery to a specific area of the body.<br /><br />Benefits:<br />• Precise drug delivery to the site of the disease (such as a cancer tumor).<br />• Side effects by reducing the effect on the body.<br />• Improving drug efficacy.<br /><br />Types of differential materials used:<br />• Nanoliposomes: Tiny lipid bubbles that carry the drug.<br />• Polymer nanoparticles: Made from biodegradable materials for Christmas music.<br />• Carbon or gold nanotubes: completed their effects or thermal cooling
