A technique for the real-time visualization of transparent gel deformation is developed, based on caged photo-activated fluorophores covalently attached to the gel network. The technique is used to quantitatively monitor the swelling of quasi two-dimensional sodium polyacrylate gels in a constrained geometry. (C) 2000 Elsevier Science Ltd. All rights reserved.
