An Integrated Intelligent Sensing Platform for Specific Identification of Biochemical Substances

This study reports an integrated intelligent sensing platform for real-time detection and identification of biochemical substances, which consists of terahertz time-domain spectroscopy (THz-TDS) technology with a ZYNQ chip. Compared with the traditional terahertz (THz) spectroscopy technology, the platform has the advantages of real-time, accurate, and specific intelligent identification. The results show that the platform can realize the specific intelligent identification of three amino acids (histidine, isoleucine, and valine) and three saccharides (pectin, sucrose, and maltose) with a response time of 320 ms and a prediction accuracy of 98%. The integrated intelligent sensing platform we have built provides a real-time, intelligent, and accurate biochemical analysis method for medical diagnosis, drug testing, and other related fields.
