Few people like to undergo a standard blood test due to its invasiveness. And that is why a team of specialists from several universities in China and the United States has teamed up to create a conceptually new way to carry out blood sampling and analysis using a special biosensor patch attached directly to the skin. It is worth noting that similar developments existed before, but they were somehow limited to a certain set of the studied patterns. What can be said about the new development of such a patch, which has the ability to analyze the state of the blood through sweat collected from the patient and transferred to a special patch compartment.
The patch itself is a rather thin and flat layer of a polymeric material made up mainly of flexible polyester of a special type, which is coated with a hydrophobic silicone coating. As a result, a thin and flexible material has extremely high adhesive properties, which allows it to be used as a kind of non-invasive means of sweat intake.
Attached directly to the patient's skin, this material, equipped with a special type of biosensors, takes the sweat particles into special sections called “micro-wells” and thus stores them until special paint is applied to them. Depending on what color and shade is obtained at the end, experts can judge about those or other results on the state of the blood of the patient under study. In addition, such results can be learned independently through the transfer of materials to a separate mobile application – thus, the development promises to be one of the most interesting.
It is worth noting that various non-invasive blood sampling options have their limitations and features, but with regard to the new development it is unlikely that the same thesis can be applied – because development specialists say that in future the patch will be supplemented and improved in its functionality. This allows us to hope for a logical continuation of this type of medical device, which patients will be able to use.
