A novel chemical approach for the development of thioesterified cellulose derivatives

Carbohydrate Polymer Technologies and Applications
In this study, thioesterified cellulose was synthesized by grafting thiol moiety onto α-cellulose, which was first oxidized with different reactive oxygen species such as H2O2, Fenton reagent (FR), and peroxyacetic acid in aqueous solution.

Study of The Reaction Mechanism to Produce Nanocellulose-Graft-Chitosan Polymer

Nanomaterials, 2018
Cellulose and chitin are the most abundant polymeric materials in nature, capable of replacing conventional synthetic polymers. From them, cellulose nano/microfibers (CNFs/CMFs) and chitosan are obtained.

Oxidized Regenerated Cellulose Mimicking a Retained Laparotomy Sponge

Case Reports in Surgery, 2022
Oxidized regenerated cellulose (ORC) is an absorbable hemostat commonly used during gynecologic surgery. We present a case in which ORC was used in a patient undergoing posterior pelvic exenteration with ureteroneocystostomy for excision of a malignant ...

Influence of pH on the Formation of Benzyl Ester Bonds between Dehydrogenation Polymer and Cellulose

BioResources
Generation of lignin-carbohydrate complex (LCC) between dehydrogenation polymer (DHP) and pulp fibers may have an important impact on the properties of pulp. In this work, the benzyl ester-type LCC was formed between oxidized cellulose and DHP.

Oxidized Cellulose and Thrombin

Experimental Biology and Medicine, 1944
SummaryOxidized cellulose injures thrombin due to its acidity. After neutralization with sodium bicarbonate it can be mixed with thrombin without altering activity. Highly oxidized cellulose contains products capable of destroying thrombin even in neutral solutions.
