Tooth tattoos for Detection of Bacterial Infection

During this time there is a tattoo on the body that is as an art form. But the researchers found a tattoo that was made in the teeth for the detection of bacterial infection.

Researchers develop ultra-sensitive system as a form of early warning for diseases through the graphene. Small sensors are made of graphene can be in a tattoo on your teeth.

In this study, researchers conducted tests using a student who asked to breathe into the sensor that is implanted in the tooth, it will take a molecular sensor of bacteria contained in the breath.

Michael McAlpine and a team of Princeton who developed a tooth tattoo is believed that the sensor is made ​​could be used to determine whether the wound is infected or not.

"Or it could be used in hospitals for patients who have weak immune systems and are very susceptible to bacteria," McAlpine said, as quoted by Medindia on Monday (04/09/2012).

Scientists create tiny graphene chemical sensor, this layer is very sticky and has a super-sensitive surface, then planted a peptide (sequence of amino acids) to the surface of graphene.

McAlpine and his team have shown that the sensor is implanted on the teeth can detect individual bacteria and is currently planning to get a license and mengkomersialkannya.

If bacterial infection is known earlier, it could soon be overcome and avoid complications worse. This is because poor oral health has been associated with the development of infection in other parts of the body.

Some ways you can do to reduce the risk of tooth decay and gum disease that is eating balanced meals, check with your dentist regularly, brush your teeth at least 2 times a day, flossing once a shari and use an antibacterial mouthwash to help reduce bacteria in the mouth.
