Mesoporous gold nanoparticles can be used to highlight faint ovarian cancer markers in samples like urine, saliva, or blood. Sponge-like gold particles may offer a more accurate way to triage women with suspected ovarian cancer, outperforming current diagnostic tools. At present, there is no effective and accessible test to accurately identify ovarian cancer and prevent women from undergoing unnecessary procedures. Using mesoporous gold nanoparticles increased that sensitivity even further compared to nonporous, or commercially available nanoparticles. Early trials showed the platform outperformed current blood tests, achieving 82 % sensitivity in detecting ovarian cancer and 98 % specificity in ruling it out.
