The project is a nose or electronic nose that seeks to be an alternative to control glucose levels in people with diabetes, exposed.
The new method aims to mimic the functioning of the olfactory system of a person where, as in the nose human, participate several sensors that react to specific molecules and generate signals that turn into information in the brain
seeks to mimic the functioning of the olfactory system of a person where, as in the human nose, several Participants participate in reacting to specific molecules and generate signals that transform into information in the brain.
In the case of this project carried out at the Research Center for Advanced Materials (Cimav), the sensors are made from polymers
Once the substances are impregnated in the sensors, the information is sent to a unit. Interpretation, where they are measured its concentrations.
The bioelectronics doctor explained that since 2015, and in collaboration with a multidisciplinary team, Development of this nose.
Dominguez Cruz explained that there are three markers that are badociated with the diabetic patient's breathing: acetone, acetoacetate and beta-hydroxybutyrate.

"What we do is develop materials that show a structural change when they interact with it." 39, one of these three markers ".
The idea, according to the specialist, is that this tool is useful for controlling glucose levels in the blood, which is "less painful and non-invasive", so that patients do not stop not the surveillance.
Currently, the control of diabetes relies on a sample of blood taken from the fingertips "but they have to do it several times a day and it is very discouraging for the person.There are those who give up or who do not have such a precise monitoring, "Dominguez said.
According to figures from the World Health Organization (WHO), the number of people with diabetes rose from 108 million in 1980 to 422 million. 2014.
the number of people with diabetes rose from 108 million in 1980 to 422 million in 2014
while in Mexico, according to figures from the latest National Survey of Health and Nutrition ( Ensanut) of 2016, the prevalence of diabetes in the Mexican population aged over 20 rose from 9.2% in 2012 to 9.4% in 2016.
It is currently estimated that in Mexico, 12 million people live with diabetes, of which only 4.5 million are diagnosed.
And among these patients, only a quarter manage to live with controlled levels.
This project is in its first stage, because the researchers are only working on the materials that react to the presence of Ketone
The project is still in its first phase because the researchers are working on materials that react to the presence Acetone
"But we hope to continue developing two other materials for two other markers, and then implement them in a device," said the doctor.
Similarly, the expert explained that, at the same time as the nose, they are also working on developing the detection of glucose levels by saliva.
are made of cellulose (paper) and a mixture of enzymes that react by changing color when they come in contact with saliva
This non-invasive medical device does not require Special counter because the color change is visible to the naked eye and can be compared to a scale that determines the amount of glucose in the patient's body.
The test strips are made of cellulose (paper) and a mixture of enzymes. Imams who react by changing their color on contact with saliva
"When a diabetic person has a higher concentration of glucose in saliva, then the bands detect a greater intensity of color and when there is a lower concentration glucose, the bands are paler, "he said.
The goal, he said, is that this form of detection can
