弗吉尼亚联邦大学的研究人员开发了一种基于尿液的纳米孔传感测试，使用数千种肽标记物检测早期卵巢癌。 Researchers at Virginia Commonwealth University develop a urine-based, nanopore sensing test for early ovarian cancer detection using thousands of peptide markers.

一种新的基于尿液的卵巢癌检测可以帮助及早发现这种疾病。 A new urine-based test for ovarian cancer could help detect the disease early. 弗吉尼亚联邦大学的研究人员发现，卵巢癌患者的尿液中存在数千种称为肽的小分子。 Researchers at Virginia Commonwealth University have found that thousands of small molecules, called peptides, are present in the urine of individuals with ovarian cancer. 然而，现有的检测方法并不简单或具有成本效益。 However, existing detection methods are not straightforward or cost-effective. 为了解决这个问题，该团队转向纳米孔传感，它有可能同时检测多种肽。 To address this issue, the team turned to nanopore sensing, which has the potential to simultaneously detect multiple peptides. 这项技术涉及让分子通过一个微小的孔，并测量它们移动时电流或其他特性的变化。 This technique involves passing molecules through a tiny pore and measuring changes in electrical current or other properties as they move through.
