Alginic acid was converted to a variety of ammonium alginate derivatives carrying diverse chemical cargo such as analgesics, antibiotics, and enzymes. These functional polymers could be fashioned into nanofibrous mats by electrostatic spinning. The therapeutic payload could be released in functional form by a simple ion exchange mechanism. Prospects in wound healing are discussed.

The cell wall of 24-h zygotes of Fucus serratus is composed of 3 layers--an inner fibrillar layer (sulphated fucan), an outer fibrillar layer (alginic aicd/cellulose) and an exterior amorphous layer (sulphated fucan, alginic acid). The 2 layers containing sulphated fucan are preferentially thickened at the rhizoid pole. Light- and electron-microscope autoradiographic pulse-chase experiments on ...

A set of chitosan-alginic acid hydrogels were prepared for multiple encapsulation and release antibiotics future application in combination therapy. Vancomycin, ciprofloxacin amoxicillin used as models, widely therapy, either individually combination. The by a simple, low cost solventfree approach based on complexation between chitosan alginic followed crosslinking with CaCl2 to enhance structu...
