Gazelle Diagnostic Device

Product Description

Gazelle is a compact, rugged, and portable battery-operated point-of-care test diagnostic device for anemia and sickle cell disease (SCD) with results in just minutes. There are two variants of the device, the Gazelle Hb Variant and the Gazelle malaria. A commercialized tool for anemia is being developed with the goal of a one-minute 25-cent noninvasive diagnostic tool for screening anemia, malaria, and SCD using an optical finger sensor.

Design Specifications

The 3.5 kg portable device operates on the Magneto-Optical Detector (MOD) which works by detecting a byproduct of malaria infection in a drop of blood. When malaria parasites consume red blood cells, they create paramagnetic iron-containing crystals called hemozoin inside red blood cells as shown below. The magneto-optical sensors in the reader measure hemozoin levels. In the case of sickle cell, the reader uses microchip electrophoresis to identify and quantify hemoglobin levels in a blood sample inserted into a cartridge that goes directly into the reader. The device is designed with an in-built battery that can be recharged to run the whole day using an android phone charger. The device can run about 35 to 40 samples a day.
