The Application of Novel Optical Sensors (Optodes) in Experimental Plant Ecology

Progress and Perspectives in Non-Invasive Bioprocess Analysis and Biogeochemical Interaction
  • Dirk Gansert
  • Stephan Blossfeld
Part of the Progress in Botany book series (BOTANY, volume 69)

The state of the art of optical chemical sensors, optodes, as an enabling technology for non- and minimal invasive bioprocess analysis in plant ecological research is presented. The measuring principle of optodes is briefly described and discussed in respect of their performance, physical properties and analytical efficiency for parameters, such as O2, CO2, temperature or pH, used as measures of bioprocesses. Independence of measurement from the state of aggregation is a major technical a dvantage of optodes that overcomes present limitations of conventional optical sensor techniques. Novel hybrid optodes that provide simultaneous information of two parameters, such as O2 and pH, at the same spot are introduced. A survey of the application of optodes for in vivo bioprocess analysis during the past decade is presented, particularly the use of oxygen optodes in plant ecophysiological research.
