Confocal fluorescence and Raman microscopy in industrial research

 Modern chemical and pharmaceutical industrial research benefits from improved spectroscopic tools. New developments in confocal fluorescence and Raman microscopy lead to an increase in sensitivity, selectivity and speed of microscopic imaging and fluctuation analysis resulting in a better understanding of structure–property relationships essential for targeted development. In this paper we report on the application of fluorescence and Raman microscopy for characterizing the morphology of polymeric multiphase solid-state samples and on new developments in the corresponding correlation spectroscopies for the characterization of the dynamics of complex colloidal systems in the liquid state. In the case of fluorescence new technological opportunities are gained by two-photon excitation. Received: 5 February 1998 Accepted: 16 February 1998
