Development of antimicrobial oxidized cellulose film for active food packaging.
Carbohydrate Polymers, 2021Foodborne diseases caused by bacteria have aroused ongoing concerns for food safety. Most existing packaging plastics bring pollution and potential toxicity. Here antimicrobial dialdehyde cellophane (DACP) was developed by periodate oxidation.

Oxidation of macroradicals in celluloses and cellulose nitrate
Polymer Science U.S.S.R., 1990The ESR method has been used to study the reaction of oxidation of macroradicals in UV- and γ-irradiated cotton cellulose and cellulose nitrate with oxygen dissolved in these polymers. The degree of oxidation of the alkyl radicals in the polymers studied did not exceed 30% which is apparently linked with the diffusion difficulties of access of oxygen ...

Biodegradation of oxidized regenerated cellulose
Carbohydrate Research, 1990The in vitro solubilization and degradation of regenerated cellulose was studied under conditions which approximate those found in vivo, when the material is used as an adhesion barrier to assist normal wound repair. Factors affecting solubilization which were examined included the effects of serum or plasma, and the presence of hydrolytic enzymes ...

Periodate Oxidation of Crystalline Cellulose
Biomacromolecules, 2000Conversion of 1,2-dihydroxyl groups to dialdehyde by periodate oxidation is a useful method of derivatizing polysaccharides but has not been extensively utilized in derivatization of cellulose because of complicacy due to the crystalline nature of cellulose.

Electrocatalytic Oxidation of Cellulose at a Gold Electrode
ChemSusChem, 2014AbstractThe electrochemical properties of cellulose dissolved in NaOH solution at a Au surface were investigated by cyclic voltammetry, FTIR spectroscopy, the electrochemical quartz crystal microbalance technique, and electrochemical impedance spectroscopy. The reaction products were characterized by SEM, TEM, and FTIR and NMR spectroscopy. The results

Oxidation and sulfonation of cellulosics
Cellulose, 2007Bleached hardwood (HW) kraft pulp and derived nanocellulosic structures were modified by a periodate oxidation followed by treatment with sodium bisulfite to yield the corresponding C2/3 sulfonates. The impact of this oxidative–reductive protocol on the chemical and physical properties of cellulose was evaluated by determining physical dimensions ...

PERITONEAL REACTION TO OXIDIZED CELLULOSE
Archives of Surgery, 1948RECENTLY there has been added to the armamentarium of the surgeon a gauzelike material which is completely absorbed in the tissues and serous cavities. This material is known as oxidized cellulose. Its physical and chemical properties have already been thoroughly described in the literature.
