Paper Abstract

A cell array biosensor was developed, composed of thousands of individual bacteria cells expressing a reporter gene that responds to the presence of environmental pollutants. The single cell array was produced by immobilizing the cells on an optical imaging fiber. A high-density array of microwells was fabricated on the optical imaging fiber's distal face by selectively etching the individual fibers cores. Each microwell was used to accommodate a single living bacterium, allowing simultaneous monitoring of the genetic responses of all the cells in the array. The optical imaging fiber cell array platform provides a powerful tool for the fabrication of whole cell biosensors for various environmental and industrial applications.
