Problem being addressed

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

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

  • 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

Tested in Tehran, Iran in 2010.

Funding Source

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