Through their computational power and connectivity, smartphones are poised to rapidly expand telemedicine and transform healthcare by enabling better personal health monitoring and rapid diagnostics.

Detection and quantification of subtle changes in red blood cell density using a cell phone.

Journal Title: 
Publication Date: 
Aug 16, 2016

Magnetic levitation has emerged as a technique that offers the ability to differentiate between cells with different densities. We have developed a magnetic levitation system for this purpose that distinguishes not only different cell types but also density differences in cells of the same type.

Robust dipstick urinalysis using a low-cost, micro-volume slipping manifold and mobile phone platform.

Microfluidics and lab-on-a-chip technologies have made it possible to manipulate small volume liquids with unprecedented resolution, automation and integration.

Albumin testing in urine using a smart-phone.

Journal Title: 
Publication Date: 
Oct 02, 2013

We demonstrate a digital sensing platform, termed Albumin Tester, running on a smart-phone that images and automatically analyses fluorescent assays confined within disposable test tubes for sensitive and specific detection of albumin in urine.

A personalized food allergen testing platform on a cellphone.

Journal Title:
