Abstract Polymers, particularly those susceptible to undergoing biodegradation under physiological environments, can be considered the materials of choice for biomedical applications such as tissue engineering, regenerative medicine, and controlled and targeted drug delivery. The development of these relatively new fi elds of biomedical research represents the driving force towards the exploitation of renewable resources for the obtainment of biobased polymeric biomaterials. This perspective article reports on the biomedical applications of three major categories of biobased polymeric materials obtained from renewable resources, namely, polysaccharides, proteins and polyesters of natural origins. Particular emphasis is given to biobased polymers that display only minor modifi… More >

Abstract The purpose of this work was to study the effect of hydrothermal, biological and photo degradation on natural fi bres reinforced biodegradable starch-based (Mater-BiKE) composites to characterize the structural changes occurring under exposure to different environments. The composites water-uptake rate was hindered by the interfacial interactions between matrix and fi bres. Thermal, structural and morphological analysis provided useful information about the irreversible changes in the properties of the composites caused by degradation in soil and photodegradation, and their synergetic effects. The effects due to the photo-oxidation and degradation in soil on the composites depended on the different chemical composition of… More >

Abstract Fully bio-based and biodegradable starch/polylactic acid blends have received increasing attentions for their biodegradability and potential to offset the use of unsustainable fossil resources, specifically, their application in packaging. Herein, corn starch was first esterified with maleic anhydride and then compounded with polylactide (PLA) to prepare esterified corn starch/polylactic acid blends with starch content up to 35 wt%. The structures, morphologies, thermal and mechanical properties of starch or blends were investigated. The results showed that corn starch was successfully grafted with maleic anhydride, which showed increased crystallinity and particle size than native starch. Esterified corn starch/polylactic acid blends showed good… More >

Abstract Tissue engineering’s main goal is to regenerate or replace tissues or organs that have been destroyed by disease, injury, or congenital disabilities. Tissue engineering now uses artificial supporting structures called scaffolds to restore damaged tissues and organs. These are utilized to attach the right cells and then grow them. Rapid prototyping appears to be the most promising technology due to its high level of precision and control. Bone tissue replacement “scaffolding” is a common theme discussed in this article. The fused deposition technique was used to construct our scaffold, and a polymer called polylactic acids and soybean oil resin were… More > Graphic Abstract

Abstract Hydroxytyrosol (HTyr), a biophenol found in extra-virgin olive oil or olive oil by-products, well known for its strong antioxidant activity, was used as active ingredient for poly(vinyl alcohol) (PVA) matrix to develop film formulations by solvent casting process. The effect of HTyr on the morphological, thermal stability, optical, mechanical and release properties of PVA were investigated, while water absorption capacity, migration with food stimulants, water vapor permeability and antioxidant properties were tested taking into account the final application as food packaging systems. Morphological investigations evidenced homogeneity of all PVA/HTyr films, while the presence of HTyr clearly accounted for an increase… More >
