Mobile Technology Spotlight: Mobile Phone Microscopes for the Developing World
This is a guest blog contributed by Dr. Aydogan Ozcan, Chancellor’s Professor at UCLA. **
In many developing regions today, cellphones and other mobile devices have begun to play a significant role in healthcare distribution. Local networks operated by service providers allow medical staff to utilize mobile technology to treat, educate, and set follow-up appointment dates with patients. Not only can patients access information about their health, but they can meet with physicians via video over the mobile network. For regions where people may be hundreds or even thousands of miles from a local doctor or hospital, these mobile devices can become lifesaving tools.
While cell phones and other mobile devices such as PCs and tablets can serve as a source of medical information or as a virtual meeting place between a doctor and patient, the technology itself can play a more important role of improving health care in developing regions as an actual medical device. Take for example, the work of University of California, Los Angeles (UCLA), Chancellor’s Professor, Dr. Aydogan Ozcan. Ozcan is creating portable and lightweight microscopes that affix to the mobile phones, thus transforming them into a platform for conducting microanalysis of blood, bodily fluids and water samples. With Dr. Ozcan’s vision and technology research, cellphones can become a mobile medical lab that can diagnose life-threatening diseases.
Mobile Technology Saves Lives
According to Cisco’s Visual Networking Index, by the end of 2014, the number of mobile-connected devices will exceed the number of people on earth, and by 2018 there will be nearly 1.4 mobile devices per capita. The massive volume of mobile phone users drives the rapid improvements of the hardware, software and high-end imaging and sensing technologies embedded in our phones, transforming the mobile phone into a cost-effective and yet extremely powerful platform to run biomedical tests and perform scientific measurements that would normally require advanced laboratory instruments. In addition to their massive volume, cost-effectiveness, coverage and data connectivity, rapid improvements in cellphone related technologies and components over the last decade provide important insights into some of the unique capabilities that our cellphones currently have. One of the most interesting components rapidly advancing on cell phones is the optoelectronic image sensor.
The mega-pixel count of cellphone cameras has been doubling almost every two years over the last decade. These advanced optical imagers on our cellphones provide various opportunities to utilize the cellphone as a general purpose microscope that can even detect single viruses on a chip. Microscopy is one of the most widely used tools in sciences, engineering and medicine, and the creation of high-end optical microscopy and imaging platforms that are integrated into cellphones is rather important for not only telemedicine (e.g., telepathology, remote diagnostics), mobile health, and environmental monitoring applications, but also for the democratization of measurement science and higher education.
Besides microscopy, these advanced imaging and optoelectronic or electronic sensing/sampling technologies embedded in cellphones can also be utilized for various telemedicine, and mobile health-related applications including, blood analysis and cytometry, detection of bacteria or viruses and diagnosis of infectious diseases.
Big Data for Service Providers
Mobile phone based field-portable measurement tools are also digitally connected to each other, forming a rapidly expanding network. Based on the advances in the broad use of cellphones for micro-analysis, imaging, and sensing, within the next decades, we can expect several orders of magnitude increase in the number of personal microscope and diagnostic tool users globally. All of these cost-effective and ubiquitous cellphone enabled devices designed for field portable imaging, sensing and testing would generate high quality, sensitive and specific data from wherever they are being used, forming a global network. In addition to mobile phones, other emerging consumer electronics devices – especially wearable computers such as Google Glass, Samsung Smartwatch and others – might also play important roles in the future practices and designs of next-generation mobile health, telemedicine and POC tools.
Mobile phones will change the way that imaging, sensing and diagnostic measurements/tests are conducted, fundamentally impacting the existing practices in medicine, engineering and sciences, while also creating new ones. This transformation will also democratize high-end measurement and testing tools worldwide, which might significantly improve research and education institutions, especially in developing regions.
As the world becomes increasingly mobile, service providers have a unique opportunity to use their core technology and business assets to create new solutions and services to enhance their users’ experience and utility, reshape businesses and business models, and create new sources of value beyond their core access business.
