Submicrometer fiber-optic biosensors have been developed and used to measure toxic chemicals within single cells. Optical fibers that have been pulled to a distal-end diameter of less than 1 m are coated with antibodies to selectively bind the species of interest. This paper describes the use of the

Fiber optic Z-cell for CZE was designed, constructed, tested and compared with on-column detection. Ten times higher sensitivity for Z-cell in comparison with on-column detection was achieved as expected from optical pathlength ratio. Linear dynamic range was b4 orders of magnitude for both cells.
## Abstract A fiberβoptic retroreflective turbidimeter has been developed to automatically and continuously assay the cell concentration in a fermentor by measuring the turbidity of the solution as a function of the light scattered at 180Β° to the incident light. The output signal is nearly directly
