Every year, millions of drugs are discarded by consumers before they expire, assuming they have deteriorated. We must recognize that this has negative consequences for our country and the world. Furthermore, when the World Health Organization data is examined, we can see that approximately 50% of the drugs are used incorrectly or unnecessarily, or they are thrown away without even opening the box, indicating that the waste is significant. It is expected that a DNA-based ink will be developed and used in drug packaging, and drug degradation will be easily tracked. As a groundbreaking project in the field of health, the DNAINK method aims to enable drug users to detect the deterioration of drugs over time. Because the text on the drug boxes will be written with DNA ink, the goal of DNAINK is to determine whether the products still maintain their stability effectively. With the DNAINK method and barcoding technology, it will be possible to determine whether a purchased drug is genuine or counterfeit, as well as whether the material deteriorates over time.
