Classification: CPC C  G | IPC C  G

Claim 8:
9. A method of microscopy comprising:
a. permeating the biological sample with a monomer of Formula (A1):, and a monomer of Formula (B1):, to form a hydrogel according to claim 1 by non-radical polymerization;
b. isotropically expanding the composite by contacting it with an aqueous solution; and
c. viewing the expanded composite using microscopy;
wherein:
each n is an integer greater than or equal to 1;
each p is an integer greater than or equal to 1;
Z+ is a counter cation
X and Y1 are each crosslinkable moieties, and
X and Y1 covalently crosslink to end-link the monomers.
