Problem being addressed[edit | edit source]

Tuberculosis is the second largest infectious cause of death in the world. It is highly prevalent in low resource settings because the equipment necessary, fluorescence microscopes, is high cost ($40,000 USD), leading to difficulty in properly diagnosing the infection.

Detailed description of the solution[edit | edit source]

The Global Focus Microscope analyses sputum smears (saliva and mucus mixture coughed up by a patient) to detect the presence of tuberculosis and malaria. The device is portable (small size and weight), is battery operated, has up to 1000x magnification, and is a low cost option ($240 USD to manufacture).

Designed by[edit | edit source]

  • Designed by: Andrew Miller - Rice University, Houston, TX
  • Manufacturer (if different): 3rd Stone Design
  • Manufacturer location: San Rafael, California

When and where it was tested/implemented[edit | edit source]

Tested in Tehran, Iran in 2010.

Funding Source[edit | edit source]

Rice University received a $2.2 million grant from Howard Hughes Medical Institute (2006)
