It is a cartridge adaptable to the mobile phone that will record whether a compound is present in saliva, which becomes visible if the patient has diabetes. It’s as simple as pregnancy tests, where the specific marker shows in a few seconds. The project is planned to be completed in two years. They wanted a device that could identify a biomarker in a sample of saliva, and it had to emit fluorescent light so a cell phone camera could record it. They also developed a micro device that can be integrated into a cell phone and where one can place a saliva sample showing the results through the software.  FEMSA Biotechnology Center
