Cell Behavior Changes and Enzymatic Biodegradation of Hybrid Electrospun Poly(3-hydroxybutyrate)-Based Scaffolds with an...
...Published in Advanced healthcare materials
This is the first comprehensive study of the impact of biodegradation on the structure, surface potential, mechanical and piezoelectric properties of poly(3-hydroxybutyrate) (PHB) scaffolds supplemented with reduced graphene oxide (rGO) as well as cell behavior under static and dynamic mechanical conditions. There is no effect of the rGO addition u...
3D bioprinting of a trachea-mimetic cellular construct of a clinically relevant size
Despite notable advances in extrusion-based 3D bioprinting, it remains a challenge to create a clinically-sized cellular construct using extrusion-based 3D printing due to long printing times adversely affecting cell viability and functionality. Here, we present an advanced extrusion-based 3D bioprinting strategy composed of a two-step printing pro...

Chitosan functionalized poly-ε-caprolactone electrospun fibers and 3D printed scaffolds as antibacterial materials for t...
Tissue engineering (TE) approaches often employ polymer-based scaffolds to provide support with a view to the improved regeneration of damaged tissues. The aim of this research was to develop a surface modification method for introducing chitosan as an antibacterial agent in both electrospun membranes and 3D printed poly-epsilon-caprolactone (PCL) ...
Spontaneously Embedded Scattering Structures in a Flexible Substrate for Light Extraction
A flexible hazy substrate (FHS) with embedded air bubbles to increase light extraction efficiency of organic light-emitting diodes (OLEDs) is reported. In order to embed the air bubbles in the flexible substrate, micropatterned substrates are fabricated by plasma treatment, and then coated with a planarization layer. During the planarization layer ...
Polydopamine-Gelatin as Universal Cell-Interactive Coating for Methacrylate-Based Medical Device Packaging Materials: Wh...
...Published in Biomacromolecules
Despite its widespread application in the fields of ophthalmology, orthopedics, and dentistry and the stringent need for polymer packagings that induce in vivo tissue integration, the full potential of poly(methyl methacrylate) (PMMA) and its derivatives as medical device packaging material has not been explored yet. We therefore elaborated on the ...
Surface modification of an epoxy resin with polyamines and polydopamine: adhesion towards electroless deposited copper
Organic Light-Emitting Diodes with Low Turn-On Voltages and Improved Stability Featuring a PTCDI-C13:CuPc Mixed Hole Inj...
We report herein that a mixed layer of the electron-donating copper phthalocyanine (CuPc) and electron-accepting N,N'-ditridecyl perylene diimide (PTCDI-C13) can be an efficient hole injection layer (HIL) for high-performance organic light-emitting diodes (OLEDs). From photophysical, morphological, and structural studies combined with electrical an...
Influence of water vapor addition on the surface modification of polyethylene in an argon dielectric barrier discharge
In this paper, water vapor up to 41% is added to an argon dielectric barrier discharge at medium pressure to profoundly investigate the effect of water vapor addition on the surface modification of polyethylene (PE). Contact angle measurements show that the wettability of PE significantly increases after a pure argon plasma treatment. However, the ...
