The many health problems suffered by developing countries or those remote areas that leave their inhabitants isolated from any health aid, are not going unnoticed 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 early. Following this line of research, a team at Stanford University developed what they call a laboratory 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 are simple: a sample is deposited on the chip, and with the help of an electronic strip an electrical charge is applied, initiating a process that allows doctors to analyze the cells, following different criteria. For example, they can isolate cells to detect different types of cancer.

One of the remarkable aspects of this project is that this product has a cost of just a penny, and can be manufactured in just 20 minutes, as they go through a printing process taking advantage of the potential of conductive nanoparticle ink.

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