The concept and application of quality by design (QbD) principles has been and will undoubtedly continue to be an evolving topic in the pharmaceutical industry. However, there are few and limited examples that demonstrate the actual practice of incor

The interdependence of pH, CO2 and O2 during chemical and biochemical processes has driven the need to monitor them simultaneously, continuously and in situ, in order to exert better control over such reactions. We present the fabrication and perform

Optical sensors are prepared by immobilizing an indicating layer on the distal end of a fiber optic cable. Dyes, enzymes, and antibodies can all be incorporated into the layer using a variety of immobilization techniques. Much of the present work is

Despite many innovations and developments in the field of fiber-optic chemical sensors, optical fibers have not been employed to both view a sample and concurrently detect an analyte of interest. While chemical sensors employing a single optical fibe

Arrays of sensing regions are photodeposited on the distal tip of a single imaging optical fiber. First, the distal surface of the fiber is spin-coated with a thin film of poly(hydroxyethyl methacrylate). The fluorophor is then derivatized with a pho
