Synthesis, characterization and potential applications for oxidized agarose.

The knowledge of agarose (AG) oxidation using periodate as oxidizer has not been systematically explored. This paper synthesized oxidized agarose (OAG) using solid-sate and solution reaction methods; the reaction mechanism and the properties of OAG samples were systematically evaluated. Chemical structure analysis disclosed that the aldehyde group and carboxyl group contents in all OAG samples are extremely low.

Synthesis of Gentamicin-Immobilized Agar with Improved Antibacterial Activity.

To develop agar derivatives with good antibacterial activity and decreased gelling and melting temperatures, two agar-gentamycin conjugates with 9.20% and 12.68% gentamicin immobilized were fabricated by oxidation, Schiff base and reduction reaction, and characterized by a Fourier Transform Infrared Spectrometer, H nuclear magnetic resonance and an elemental analyzer.
