Skeletal density ( ρ s), on the other hand, is measured by using a pycnometry system (Micromeritics Accu-Pyc II 1340 Gas Pycnometer). The system determines density by means of the gas displacement method, which employs highly pressurized helium gas (as the measuring medium) to measure the volume of the solid matter contained inside the measuring chamber. Further to this, values of porosity are calculated from eqn (2):

It has been suggested that cryogels are more suitable for this application, as opposed to hydrogels, as a greater number of cells can be contained within the structure. With an exemption for injectable supramolecular hydrogel systems, which have been demonstrated to perform very well even after injection [ 74– 76], hydrogels in general have been cited as being too brittle to enable injection [ 27]. Injectable cryogels have been investigated as scaffolds, for drug delivery, and for wound-healing applications. Here we highlight recent advances in the development of these injectable systems relevant to the applications discussed. Kornblith, L.Z.; Moore, H.B.; Cohen, M.J.

The scientific community is especially interested in using these properties in specific drug-delivery systems; the potential of using polysaccharide-based specific drug-delivery systems in the colon has been explored [ 43], as within the colon are many polysaccharides and a large number of bacteria which secrete enzymes [ 41]. Within this work, varying the concentration of various pH-sensitive polymers was considered in terms of swelling, and it was shown that abrupt changes in swelling could be obtained at a specific pH while using materials compatible with the colon. Also, assessing swelling as a function of NaCl concentration began to explore osmotic interactions of hydrogels, adding to the consideration of environmental conditions and providing data in a region often overlooked in these types of studies.
