The increase in sensitivity comes from nickel-platinum nanoparticle /news/wp-json/wp/v2/posts/118729/u201cmimics/news/wp-json/wp/v2/posts/118729/u201d that greatly increase the reaction efficiency of the test, which increases its color output, and thus its detection ability, Xia says./news/wp-json/wp/v2/posts/118729/n
Peroxidases found in the horseradish root have been widely used to generate color in diagnostic tests for decades. However, they have limited reaction efficiency and thus color output, which has inhibited the development of sensitive diagnostic tests, Xia says./news/wp-json/wp/v2/posts/118729/n
Nanoparticle /news/wp-json/wp/v2/posts/118729/u201cmimics/news/wp-json/wp/v2/posts/118729/u201d of peroxidase have been extensively developed over the past 10 years, but none have achieved the reaction efficiency of the nanoparticles developed by Xia and his team./news/wp-json/wp/v2/posts/118729/n
