A Tattoo that lets you know when you are Ill



Scientists have long been interested in implanting sensors that can monitor changes in body chemistry. Such sensors could prove useful for tracking the progress of diseases or how well a patient is responding to treatment.

The downside to such sensors is that they couldn’t remain inside long enough and end up losing their effectiveness or getting rejected by the body the longer they stayed inside.

A team of scientists based at the Johannes Gutenberg University Mainz in Germany (JGU) has now succeeded in building a sensor that can remain in the body for months on end after implantation.

Built from modified gold nanoparticles that have unique receptors for particular molecules, the sensors get implanted underneath the skin and come encased in artificial tissue.

What makes the gold nanoparticles so remarkable is the way they change color in response to changes in their environment. The researchers wanted to take advantage of this feature to create color-changing tattoos.

“Our sensor is like an invisible tattoo, not much bigger than a penny and thinner than one millimeter,” clarified JGU Nanobiotechnology Group head Prof Carsten Soennichsen.

Published in the Nano Letters journal, the study involved researchers testing the sensors on hairless rats. As the rats received antibiotic doses, researchers noticed the sensors changing color.

The scientists used a non-invasive instrument to detect changes in color. They observed that the sensors stayed stable and continued working for months.

“As they [the nanoparticles] can be easily coated with different receptors, they are an ideal platform for implantable sensors,” said Dr. Katharina Kaefer, who was the lead author of the study.

So far, it seems that gold nanoparticle sensors have a place in our future. They may prove useful in drug development by monitoring drugs and biomarkers in our bodies. They may also work in medical research, chronic disease management, or medicine.
