AG_Chopsticks by Yap Hock Heng from singapore

In the past, royalties in the Korean kingdom uses silver(AG) chopsticks to test their food for poison. Although the presence of poison is not of much concern in our modern day society, there is however a growing awareness for the detection of harmful bacteria within our food. Hence the mounting interest in food science and the advances made in biosensors. A major breakthrough in this area of science is the use of chromatic conjugated polymer as a fast and simple way to detect harmful food bacteria like E.Coli and Salmonella. When the organic polymer comes into contact with these bacteria, the proteins within the bacteria will cause it to change colour. By incorporating the polymer within a pair of silver chopsticks, users are provided with a simple tool to test the freshness of their food. This will enable users to safeguard themselves from possible food poisoning and give themselves a piece of mind when dining. My design aims to update a traditional practice with present day technology, and make it relevant for dining in 2015.
