Optimization of the formulation of an original hydrogel-based bone cement using a mixture design.

Highly swelling polymers, i.e. superabsorbent hydrogels, are hydrophilic, three dimensional networks that can easily absorb a significant amount water, fluid or drug.

Acrylic bone cement and starch: Botanical variety impact on curing parameters and degradability.

Acrylic bone cements are a conventional solution to heal bone defects. Starch is often added to the cement to improve its degradability and resorbability. The most used botanical variety is corn starch; few studies or applications deal with other varieties.

Evaluation of a bio-based hydrophobic cellulose laurate film as biomaterial--study on biodegradation and cytocompatibility.

The study aims to validate an original bio-based material, obtained by grafting fatty chains, and more especially lauric chains (C12) onto cellulose, for medical applications. The mechanical properties of the synthesized cellulose laurate (C12) are close to those of petrochemical ones such as low density polyethylene. This cellulose-based polymer is transparent, flexible, and hydrophobic.
