ELECTRONIC SYSTEM FOR MODELING CHEMICAL REACTIONS AND BIOCHEMICAL PROCESSES

摘要

A system for modeling chemical reactions using analog or hybrid-analog-digital electronic circuits. The system exploits similarities between the kinetic rates of chemical reaction and the rates governing current flow in electronic devices such as bipolar junction transistors (BJTs) and metal oxide semiconductor field effect transistors (MOSFETs) operating at subthreshold conditions. These devices, which accurately model the stochastics of chemical processes, can networked into large array to model chemical reaction networks, including biochemical reactions and genetic processes such as activation, induction, transcription, and translation.
