The present invention relates to a non-amphiphile-based water-in-water emulsion composition. The non-amphiphile-based water-in-water emulsion composition includes a water-soluble polymer, a non-amphiphilic lyotropic mesogen encapsulated by the water-soluble polymer; and water. In one embodiment, the non-amphiphilic lyotropic mesogen includes, without limitation, a lyotropic chromonic liquid crystal, and more specifically disodium cromoglycate (DSCG). In another embodiment, the water-soluble polymer can include, without limitation, a polyacrylamide, a polyol, a polyvinylpyrrolidone, a polysaccharide, or a water-soluble fluoride-bearing polymer. The present invention also relates to a porous hydrogel made with the use of the non-amphiphile-based water-in-water emulsion. The present invention further relates to using the emulsion and hydrogel for various applications.

A method for inhibiting the growth of a microorganism using an effective amount of one or more of the following synthetic brominated furanones: (i) 4-bromo-5Z-(bromomethylene)-3-methylfuran-2-one; (ii) 3-(dibromomethyl)-5-(dibromomethylene)furan-2-one; (iii) 3-(bromomethyl)-5-(dibromomethylene)furan-2-one; (iv) 4-bromo-3-(bromomethyl)-5Z-(bromomethylene)furan-2-one; or (v) 4-bromo-5-(dibromomethyl)-3-methylfuran-2(5H)-one. The brominated furanones inhibit the growth of both fungi and bacteria, including the fungal species
Candida albicans, Gloeophyllum trabeum, Chaetomium globosum
, and
Trametes versicolor
and the bacterial species
Pseudomonas aeruginosa
. The brominated furanones can be used topically or internally to treat human infections, and can be used to treat other objects, such as wood building supplies, to prevent fungal rot.
