Created a patch that detects antibiotic resistant bacteria

a New patch can reduce the incidence of bacterial infections
If you badly cut yourself with a knife or get another wound in your body can get hazardous microorganisms. They can cause different bacterial infections, for treatment which may require antibiotics. Unfortunately, many microorganisms tend to develop resistance to medications, so the sooner they are found in your body, the more chances of a cure you will have. To quickly identify the presence in the wound , Chinese scientists have created the patch, which is like a traffic light able to be painted in green, yellow and red colors. But what are these shades and how the bandage can recognize a threat ?
The new invention of the staff of the Institute of applied chemistry, Chinese Academy of Sciences was described in a scientific journal . The researchers engaged in the creation of changing the color of the patch because when you need health it can reduce the incidence of intestinal infections and other diseases arising from the ingestion of dangerous bacteria.
Quick treatment for bacterial infections
In the course of scientific work, the researchers were able to create a green material, which after four hours after sticking on the wound is painted in yellow or red. If the patch turns yellow, it means that the wound has bacteria, but they can be easily destroyed by antibiotics. But if the material takes on a red hue, it means that its constituent substances entered into a reaction with enzymes that are bacteria immune to drugs.
As you might guess, in the case of staining of the patch in yellow color doctor can simply prescribe patients antibiotics. If the material turns red, the doctor can expose it to bright light, forcing him to release highly active oxygen species and thereby weaken the resistance of bacteria to . It is believed that in this way doctors can quickly stop the development of infection and help patients to avoid complications.
change the color of the patch when detected, drug-sensitive bacteria (DS) and antibiotic-resistant bacteria (DR)
Currently, the performance of the technology has been tested only on mice. Their bodies were wounds and embedded coliform bacteria. After applying new bandages she really turned red and helped scientists to quickly heal the wound with bright radiation. Exactly when the technology will be tested on humans, is still unknown.
Bacteria Escherichia coli (Escherichia coli)
Before that Chinese scientists want to improve at least two properties of the new patch. First, they want their material to recognize even a small caught up in the wound. Second, they need to make the recognition of bacteria and the color change of the patch was much faster four hours.
Generally, the creation of such patches is ongoing and different groups of scientists. Today, there are a huge number of dressings, which can quickly eliminate physical pain and even help in the fight against Smoking. Recently, American scientists have impregnated adhesive substances that promote rapid healing of wounds. To read about what they did in the end, in our special material.
