This Chip Costs only a Penny, and can Detect Diseases like Cancer and Tuberculosis

The many health problems faced by developing countries or those who live in remote areas which leave them isolated from any health assistance are not being overlooked by scientists and professionals from different parts of the world.

In recent months we have seen many projects that seek to provide alternative solutions with low cost products for the detection of diseases that can cause death if not diagnosed in time. Following this line of research, a team from Stanford University developed what they call a “lab on a chip.”

It is a chip that can analyze cell samples to detect the presence of diseases such as malaria, tuberculosis or cancer.

Although the study can be complex, the dynamics is simple: a sample is deposited on the chip, and an electric charge is applied with the aid of an electronic strip, initiating a process that allows physicians to analyze the cells, according to different criteria. For example, they can isolate cells to detect different types of cancer.

One of the highlights of this project is that this product has a cost of just one cent, and can be manufactured in just 20 minutes, as they go through a printing process exploiting the potential of conductive nanoparticles ink.

While it is not a replacement for traditional medical procedures, this is undoubtedly a resource that opens new doors for the early diagnosis of diseases.
