Most of artificial intelligence systems are implemented with silicon-based chips which have high area complexity and power cost when facing large systems. Is it possible to use bio-chemical materials to implement artificial intelligence systems more efficiently?</font></p>

Previous researches [1], [2] have shown some interesting applicatoins of such materials, which implemented a "probabilistic switch" and a pattern recognition machine, respectively. Computation systems in this field are usually based on DNA strand displacement reactions. [3] and [4] provide vivid demonstration of how such reactions proceed in molecular level.</font></p>

                                        <p><font size="4">In this project, we have employed DNA reactions to implement neural networks which are basic components in artificial intelligence systems. Specifically, using molecular concentrations as input and output signals, we propose and demonstrate computation models for weighted summation (including multiplication and addition) and activation functions (e.g, ReLU and Sigmoid) which are arithmetic operations in neural networks. Also, the classical backpropagation algorithm which is utilized in the training process can be similarly constructed (which has not been studied in molecular computing to our best knowledge). Based on these models, we synthesize basic neural networks with DNA strand displacement reactions.</font></p>
