In the United States created an electronic photoacoustica patch that can track biomolecules in deep tissues. including hemoglobin. According to experts from the University of California at San Diego, such a patch will help detect life-threatening conditions, such as malignant tumors.
Hemoglobin is a protein that deliversoxygen in body tissues. How well the blood passes through the tissues depends on the amount of this protein. If the passage is poor, this may, for example, cause organ dysfunction. To diagnose life-threatening conditions, hemoglobin levels need to be monitored.
There are several ways to control the levelhemoglobin. These are, for example, MRI and X-ray computed tomography, but they require bulky equipment. Researchers at the University of California, San Diego have come up with a new way - using a flexible patch that tracks hemoglobin using a photoacoustic method.
The patch contains laser diodes.piezoelectric transducers. All of this is based on silicone. Due to the operation of these laser diodes and transducers, a three-dimensional image of biomolecules is obtained.
According to the authors of the development, the electronic patch is safer than other methods and is also easily attached to the skin.
The development is discussed in more detail in an article published in Nature Communications.
