Mobile_phone.png Here’s the house call of the future. A prototype cell phone that monitors HIV and malaria patients and tests water quality in undeveloped areas or disaster sites. Data is then be sent via the cell phone to a hospital for analysis and diagnosis.

The imaging platform is already here. It’s called LUCAS and has been experimentally installed in a cell phone and a webcam, each of which then takes an image of blood, saliva or other fluids using short-wavelength blue light. LUCAS can identify and count the microparticles instantly by using a decision algorithm to compare the captured images to a library of images.

The technology is the brainchild of electrical engineer Aydogan Ozcan of UCLA. His latest version, called holographic LUCAS, is described in the journal Lab On A Chip. Holographic LUCAS can identify smaller particles than before, such as E. coli. Ozcan’s next step is to build a handheld device for people in remote areas to use to monitor the spread of disease, allowing doctors to know where they’re most needed fast.

DEMOCRACY DOES NOT EXIST...

without free and fair elections, a vigorous free press, and engaged citizens to reclaim power from those who abuse it.

In this election year unlike any other—against a backdrop of a pandemic, an economic crisis, racial reckoning, and so much daily crazy—Mother Jones' journalism is driven by one simple question: Will America will move closer to, or further from, justice and equity in the years to come?

If you're able to, please join us in this mission with a donation today. Our reporting right now is focused on voting rights and election security, corruption, disinformation, racial and gender equity, and the climate crisis. We can’t do it without the support of readers like you, and we need to give it everything we've got between now and November. Thank you.
