Time change is important for our sensory organs when they recognize information. In the process of DNA nanostructure formation, order of change, timing, and time change of concentration are very important factors. Existing DNA devices such as logic gates focus on input and output. And, DNA structures such as Oscillator can control output concentration precisely. However, there is a problem that it is hard to get different output about.</p> <img src="http://openwetware.org/images/6/60/Gomi_03.png"> <p><h3>2.ほにゃらら</h3><br> Nowadays, the importance of the food is increasing. Researches on the sense of taste is very hot. One of them is molecular gastronomy. In molecular gastronomy, we study cooking from the perspective of chemistry or physics. Studying a principle of the food which produced as a result of chemical reaction at a molecular level, we cook delicious food chemically. In addition, some researchers convert the chemical information of taste components (such as sweetness, saltiness, acidity, bitterness, and umami ) into electric information, study quantitatively, try to reproduce various tastes to stimulate a tongue by electricity. Furthermore, there has been made pretty food such as crackling candy which contains tiny CO2 gas bubble or a candy which changes its color when it is mixed. Such food are entertainer which approaches to a sense organ. </p>
<h1>Motivation</h1> <p>Therefore, in this study, we designed a system which can effuse several DNA molecules at regular intervals in order to control time and order of DNA reactions. In this system, variable molecules can be effused by adapting output DNA to liposome-modified DNA. This system is consisted of a group of biomolecules including DNA, and has high biocompatibility. So we hope that we apply this system to DDS (Drug Delivery System) by effusing variable medicines contained in liposomes to the affected part at regular intervals. However, we pursued the entertainment property appealing to our sense. That is, we designed “Taste Virtual Reality System”, which stimulate taste bud, and present taste substance.</p>
