But what does it actually mean?<\/p>\n\n\n\n<p><strong>Biocompatibility definition:<\/strong> In simple terms, biocompatibility refers to how well a material interacts with the human body without causing <strong>adverse reactions, toxicity, or immune rejection<\/strong>. A <strong>biocompatible material<\/strong> must be safe, non-toxic, and capable of functioning in a biological system without causing harm.<\/p>\n\n\n\n<p>The <strong>importance of biocompatibility<\/strong> cannot be overstated. From <strong>hip replacements<\/strong> to <strong>heart stents<\/strong>, from <strong>surgical sutures<\/strong> to <strong>contact lenses<\/strong>, biocompatibility plays a critical role in ensuring <strong>medical device safety<\/strong>.
