Open AccessUltrathin collagen type I films formed at the air-water interface
Collagen-based biomaterials with oriented fibrils have shown great application potential in medicine. However, it is still challenging to control the type I collagen fibrillogenesis in ultrathin films. Here, w...

Open AccessCrystallization and degradation behaviour of multiblock copolyester blends in Langmuir monolayers
Supporting the wound healing of soft tissues requires fixation devices becoming more elastic while degrading. To address this unmet need, we designed a blend of degradable multiblock copolymers, which is cross...

Open AccessDegradation kinetics of oligo(ε-caprolactone) ultrathin films: Influence of crystallinity
The potential of using crystallinity as morphological parameter to control polyester degradation in acidic environments is explored in ultrathin films by Langmuir technique. Films of hydroxy or methacrylate en...

Open AccessHighly crystalline PCL ultrathin films as thermally switchable biomaterial coatings
Semi-crystalline oligomers are explored as functionalized thermoswitchable coatings for modification of biomaterials surface. Highly crystalline oligo(ε-caprolactone) (OCL) films are prepared at the air–water ...

Understanding the impact of crystal lamellae organization on small molecule diffusion using a Monte Carlo approach
Many physicochemical processes depend on the diffusion of small molecules through solid materials. While crystallinity in polymers is advantageous with respect to structure performance, diffusion in such mater...

Relation between Surface Area and Surface Potential Change during (co)Polyesters Degradation as Langmuir Monolayer
Polyhydroxyalkanoates (PHAs) are degradable (co)polyesters synthesized by microorganisms with a variety of side-chains and co-monomer ratios. PHAs can be efficiently hydrolyzed under alkaline conditions and by...

The interplay between network morphology and degradation kinetics of polymers: Theoretical and experimental analysis by means of a 2D model system
Network formation by cross-linking is a common method to incorporate functions like elastic deformability, shape-memory capability or hydrogel formation into polymer materials for medical applications. Since t...

Self-stabilized fibronectin films at the air/water interface
Fibronectin (FN) is a mediator molecule, which can connect cell receptors to the extracellular matrix (ECM) in tissues. This function is highly desirable for biomaterial surfaces in order to support cell adhes...

Open AccessInterfacial properties of morpholine-2,5-dione-based oligodepsipeptides and multiblock copolymers
Oligodepsipeptides (ODPs) with alternating amide and ester bonds prepared by ring-opening polymerization of morpholine-2,5-dione derivatives are promising matrices for drug delivery systems and building blocks...

The influence of pH on the molecular degradation mechanism of PLGA
Poly[(rac-lactide)-co-glycolide] (PLGA) is used in medicine to provide mechanical support for healing tissue or as matrix for controlled drug release. The properties of this copolymer depend on the evolution o...
