One embodiment of the dilution resistant composition comprises a hyaluronate-based viscoelastic agent and a low viscosity, polymer-containing solution. The hyaluronate-based viscoelastic can be an aqueous solution sodium hyaluronate having an average molecular weight greater than 750,000 Daltons and a concentration by weight between 0.5% and 3%. The polymer-containing solution can contain a polymer selected from the group consisting of chondroitin sulfate and hydroxypropylmethylcellulose. One embodiment can comprise a polymer-containing solution containing hydroxypropylmethylcellulose at a concentration by weight from about 0.05% to about 5.0% and chondroitin sulfate at a concentration by weight from about 0.1 to about 7%.

    摘要： A regenerative photovoltaic cell (1) producing a visible light-induced photocurrent comprises a transparent or translucent first substrate (2) having a back surface coated with an indium tin oxide (ITO) layer (4), a nano-structured photoanode (5) comprising an n-type semiconductor (6), such as titanium dioxide, coated with a broad band absorbing melanin-like material (7), a second substrate (8) with a carbon/platinum coating (9) forming a counter cathode and a liquid electrolyte (14) between the photoanode and cathode, said electrolyte re-oxidising the melanin-like material (7) after it has absorbed incident radiation, thus returning it to the ground state. A p-i-n type photovoltaic cell is also exemplified in addition to other electronic devices employing melanin-like materials and processes for the production of mechanically stable, flexible films of melanin-like material for use in electronic devices.
