Abstract
A brief review of the development of various optical chemical sensors which can be applied in environmental analysis is presented. Only those devices which make use of the immobilized reagent phase are discussed. Immunosensors and generic techniques, such as surface plasmon resonance, are not included. Current limitations of the technology and future trends are discussed. Activities at Cranfield on environmental optical diagnostics are presented.Keywords
