Project Overview

The immunoassay system consisted of a bench-top instrument using proprietary technology and chemistry to detect ultra-low molecular quantities. The instrument brought together many disciplines including embedded 32-bit processor technology, multi-axis motion control, sensitive optics, embedded real-time software, GUI HMI, and a web-based interface application. ZoZo Engineering was responsible for product definition all the way through to realization of the instrument’s embedded electronics and software. ZoZo Engineering finished the development by releasing a comprehensive transfer-to-manufacturing package.
