 Fake drugs or counterfeit medicines are fundamental security problems. And as a shocking example, counterfeit medicine for malaria and pneumonia cause 250,000 deaths of children each year. As we have more online pharmacists, we've seen more and more counterfeit medicines. We developed anti-counterfeit technology using natural materials and proteins so that pharmaceutical companies can make sure that their products are protected. And also the end users, such as a patient, can verify their medicine right before they take it. This, our Edible Unclone Tag, is made of all protein, 100%. We use French protein and silk proteins, nothing else. All of them are edible and digestible. Basically, we have a method to broadcast micro-particles that generate completely random patterns. So it's really hard to duplicate or clone it. The one nice thing about fluorescence signals is that it's not really visible from naked eyes. So nobody can just take the photo of your medicine and then duplicate. So you have to use special excitation light and also you need an emission filter to look at images. We can make many of these tags, but there's no way you can make exactly the same tag again. So that's the idea of the unclonable tags. We can attach the tag on the surface of the medicine or the whole process can be embedded as it's part of a manufacturing process. And then after the patient or end user can verify the tag and they can get all the information about those frequency and manufacturer. So the next step is to make very reliable mobile app to take fluorescence images and as well as to conduct access to the server and we have some automatic authentication process.
