Arizona State University researchers have developed a diagnostic device that uses LEDs and microelectronic amplifiers to detect diseases.

Integrascope can analyse patient fluid samples mixed with microparticles or nanoparticles. Once this mix is placed on the device’s hydrophobic surface, an LED is focused on it. As the drop evaporates, the particles will stick together if the sample contains an infectious agent or targeted protein.

The infectious agent or targeted protein moves to the centre of the drop, while the particles that have not stuck together move to its surface.

Researchers have built prototype devices to measure C Reactive Protein in human serum, which can be helpful to detect a variety of inflammatory conditions, and are hoping to collaborate with Latin American universities, government leaders and entrepreneurs to develop the it further.
