普渡大学的助理教授拉姆瑟斯.V.马丁内斯（Ramses V. Martinez）说：“你可以把这种设备当成是全部用纸做的便携实验室。既经济也可以通过焚烧扔掉。”该设备需要一滴血样，就可以测试出类似葡萄糖，尿酸，L乳酸，酮尿和白细胞的化验等生物指标。
To diagnose ailments such as anemia, malnutrition and liver and kidney disorders, lab work is usually required to detect biomarkers. Researchers are aiming to take the costly lab work out of such diagnostics with a self-powered, paper-based electrochemical device that can be used in regions lacking medical resources, Phys.org reported Aug. 22. “You could consider this a portable laboratory that is just completely made out of paper, is inexpensive and can be disposed of through incineration,” said Ramses V. Martinez, an assistant professor at Purdue University. The device requires a pinprick of blood for a sample, and can detect biomarkers such as glucose, uric acid and L-lactate, ketones and white blood cells. The assays change color to show results, and researchers have also developed an application that allows mobile phones to read the “colorimetric” tests, provide results and facilitate a consultation with an expert remotely. Martinez envisioned future tests to diagnose dengue fever, yellow fever, malaria, HIV and hepatitis.
