What is it about?

Sensitive detection of antibodies for medical diagnosis needs specialized equipment and trained personnel. By combining the use of nanoparticles, microfluidics, and magnetism, we developed a small and simple device that detects antibodies in a short time, with excellent sensitivity, and with a small volume of reagents.

Why is it important?

This is the first time this kind of device is done in a thermoplastic, ideal for mass production. Our system can be automatized and adapted to work without the need for specialized laboratory equipment or trained personnel. The perspective is to develop a simple diagnosis device that will allow making fast, sensitive, and cheap tests. Unlike rapid tests, like lateral flow, our device can make quantitative tests.

Perspectives

This article is the first step for developing a functional device that can be useful for making good quality diagnosis accessible for low-income people in the developing world.
