In contrast to the usual inclusion of disulfide bonds within a polymer structure to facilitate bio-degradation, we have designed a self-curing "one pot" hyperbranched polymer capable of forming crosslinked gels under reducing conditions abundant in tumoural tissue.

Here, the application of the gel-forming carbohydrate polymer, gellan gum, for the electrophoresis and isolation of DNA is detailed. Gellan gun forms gels in the presence of divalent metal cations, and the gels can be converted back to a solution by the addition of a chelating agent such as EDTA. Also, gellan electrophoresis gels can be formed using diamines. These gels are reversible by increa...

Mucosa-adhesive gels can be used as a useful mean of delivering drugs to or via mucosal membranes, and in particular buccal mucosa. Carbomers are among the best mucosa-adhesive materials known. The aim of this study was to compare the results obtained from the mucosa-adhesive strength of aqueous gels containing Carbomers, either alone or in combination, to the data obtained from assessing the d...
