近日,英国科学家研制出一种新型艾滋病病毒(HIV)检测方法。与目前的检测方法相比,该方法的灵敏度提高了10倍以上,但成本却相当低廉,为发展中国家HIV感染者的诊断和治疗带来了福音。目前,利用人体唾液检测HIV的手段已相当简单快捷,但其缺点是只有在病毒数量达到一定浓度时才能检测出来。而新检测方法采用纳米技术,能够使待测样本的检测结果显示为红色或者蓝色,用普通 Recently, British scientists developed a new HIV test. Compared with the current detection method, the sensitivity of this method is more than 10 times, but the cost is very low, which brings the gospel to the diagnosis and treatment of HIV-infected people in developing countries. Currently, the use of human saliva detection of HIV has been quite simple and quick means, but the disadvantage is that only when the virus reaches a certain concentration of concentration can be detected. The new detection method using nano-technology, the test results can be tested samples showed red or blue, with ordinary
