agar

A series of gelatin-based hydrogels was prepared, and the effects of different crosslinking agents and agar content were studied in detail. Results indicate that borax and glutaraldehyde are good crosslinking agents. Moreover, all samples were described with a hindered Fickian water diffusion, making it an interesting choice for medical applications.

In this work agar- and borax-based hydrogels with and without the addition of poly(vinyl alcohol) (PVA) at different concentrations were synthesized. Hydrogels were modified by the same amount of acetylsalicylic acid (ASA) which exhibits antithrombotic properties. The effect of modification by ASA on the properties of hydrogels was analyzed.
