The only way I know to fix them without nicking them is to use a high pressure freezer and then use freeze substitution.

Can you please share your favorite worm fixation methods with me?? I've
had great success in EM prep using 2% PFA 0.2% gluteraldehyde in
cocodylate buffer. BUT-I had to "nick" the worms to get infiltration of
the fixative. I now have a user who would prefer to avoid the "nicking"
technique for his application, but so far, we're experiencing
insufficient fixation. Any/all advice is very welcome!!!
Many thanks in advance!
