Due to presence of hydroxy and carboxy functional groups, xanthan gum is amenable to various chemical modification for producing derivatives such as carboxymethyl xanthan and carboxymethyl hydroxypropyl xanthan with desirable properties for end use.

Bone tissue engineering has been continuously developing since the concept of “tissue engineering” has been proposed. Biomaterials, as the basic material for the fabrication of scaffolds, play a vital role in bone tissue engineering.

Functional active wound dressings are expected to provide a moist wound environment, offer protection from secondary infections, remove wound exudate and accelerate tissue regeneration, as well as to improve the efficiency of wound healing.

This article reviews the recent advances and various factors affecting the improvement of the biological properties of calcium phosphate for bone repair.

Tissue adhesives have been introduced as a promising alternative for the traditional wound closure method of suturing.

This review discusses the extrusion process parameters and their impact on the mechanical properties of composites reinforced with lignocellulosic fibers.

Hydroxyapatite (HA) is a member of the Ca apatite family.

This article reviews recent advances in the crosslinking chemistries of biomimetic hydrogels prepared from PEG-based macromers.

The design criteria for injectable, in situ-gelling hydrogels are reviewed in conjunction with highlights on recent progress in the preparation of injectable PEG and PEG-analogue poly(oligoethylene glycol methacrylate) (POEGMA) hydrogels.

The chemical properties of curcumin as well as its proposed mechanism of action as an anti-cancer therapeutic are reviewed. Recent approaches to curcumin delivery are described.

Fucoidans vary in structure and milder extraction techniques are needed to retain unique structural properties; enzymes may help unlock specific structural features of fucoidans.

“Trees in miniemulsion” – the biopolymer lignin was used to generate biodegradable nanocontainers via an interfacial polyaddition reaction.

In situ, time-resolved characterisation of an alginate–acrylamide tough hydrogel dynamic formation process indicate routes to intervention and modification of chemo-physico-mechanical properties.

We investigate the effects of material morphology, exposure time, exposure methodology and concentration of graphene oxide (GO) and GO-based materials on two pathogenic bacteria.

Glycation of proteins is often considered as a method to improve their functional properties for promising applications in wound healing.

3D cell scaffold based on macroporous PNIPAM is cytocompatible and preserves the cell viability for more than 75 culture days.

Biomaterial scaffolds play a critical role in bone tissue engineering.

Fibrin is a well-known tool in tissue engineering, but the structure of its modifications created to improve its properties remains undiscussed despite their importance, e.g. in designing biomaterials that ensure cell migration and lumenogenesis.

Condensed tannin is a biologically derived polycation that can be combined with glycosaminoglycans (chondroitin sulfate and heparin) to prepare polyelectrolyte multilayers that promote stem cell adhesion and proliferation.

The aim of this study was the design of a 3D scaffold composed of poly(vinyl) alcohol (PVA) for cardiac tissue engineering (CTE) applications.

Polymer materials with electrically conductive properties have good applications in their respective fields because of their special properties.

Chitosan films blended with stem, leaf and seed extracts of Pistacia terebinthus for active food packaging.

In this work, solid microneedles (MNs) for skin pretreatment were systematically studied including MN height, density, spacing, and so on.

In this study, we developed conductive microgrooved tissue constructs, leading to the formation of highly packed and uniaxially oriented cardiac cytoarchitecture.
