iPhone变显微镜仅需8美元

元器件交易网讯 16日消息，iPhone能当显微镜用了！据报道，一位传染病专家通过使用三毫米球透镜将iPhone 4 s变成了相当准确的显微镜，而额外只需8美元的费用。

iPhone显微镜下样本图像

一位传染病专家和他的同事把一个iPhone 4 s变成了相当准确的显微镜。它们是通过使用双面胶带将一个三毫米球透镜固定到智能手机的摄像头上，这仅需附加8美元的费用。

这个DIY iPhone显微镜已经通过200个样本图片测试。为了检查iPhone显微镜的准确性，样品同时也使用传统的显微镜观测。通过对比来评估iPhone显微镜的准确性。

对比于传统的显微镜，iPhone显微镜精确度达到了70%。这个结果看上去是非常不错的，但是还是不够精准。显微镜必须达到80%准确度才对临床上有用。不过，研究人员相信这项技术仍然可以得到改善。

这个 iPhone显微镜已经不是第一个智能手机显微镜。早在2011年，加州大学的研究人员推出过一个类似装置。

DIY iPhone Microscope Costs $8 to Make

Internal medicine and infectious disease specialist Isaac Bogoch and his colleagues turned an iPhone 4S into a fairly accurate microscope by attaching an eight dollar, three-millimeter ball lens to the smartphone"s camera lens using double sided tape.

The DIY microscope was tested with 200 slides of stool samples from school children with different types of parasitic worms in Pemba Island, Tanzania. The slides were covered with cellophane strips and then placed up against the lens. A simple flashlight illuminated the slides from below. The doctors took photos of the samples and assessed them on the iPhone screen.

To check the accuracy of the iPhone microscope, the slide samples were also assessed using a conventional microscope.

The iPhone microscope was 70% accurate as compared to a conventional microscope. These results were promising, but not quite enough. The microscope will have to be at least 80% accurate in order to be clinically useful, according to the study which was published last March on The American Journal of Tropical Medicine and Hygiene.

The researchers are confident that the technology can still be improved.

Mobile phone diagnostic technology will likely contribute to the diagnosis of infections and non-infectious etiologies in resource-constrained settings. A first-generation mobile phone microscope using a ball lens had modest diagnostic yield for soil-transmitted helminth infections; however, newer technologies may further improve mobile phone diagnostic capabilities, but they require additional field testing in different epidemiologic settings.

Bogoth"s DIY iPhone microscope is not the first time a smartphone was used as a microscope. A similar device was created by researchers from University of California, Davis in 2011.
