Valerie,

 

          By far the simplest approach is to use second harmonic
imaging.  Starch gives a very strong SH signal.

Hi all,
We are looking for a method of imaging starch in paper using confocal
microscopy.  None of the fluorescent dyes we've tried (basic fuchsin,
crystal
violet, SF light) are useful since they also stain the cellulose in the
wood
fibres.  Starch has been hydrolyzed.  Any suggestions would be greatly
appreciated.
Thank you. 
Valerie Lawrence
