Tailored hydrogels mimicking the native extracellular environment could help overcome the high variability in outcomes within regenerative endodontics. This study aimed to evaluate the effect of the chemokine-binding and antimicrobial polymer, chlorite-oxidized oxyamylose (COAM), on the microstructural properties of fibrin and self-assembling peptide (SAP) hydrogels. A further goal was to assess the influence of the microstructural differences ...

Understanding microbial adhesion and retention is crucial for controlling many processes, including biofilm formation, antimicrobial therapy as well as cell sorting and cell detection platforms. Cell detachment is inextricably linked to cell adhesion and retention and plays an important part in the mechanisms involved in these processes. Physico-chemical and biological forces play a crucial role in microbial adhesion interactions and altering ...

Abstract The synthesis and characterization of small monodisperse multimodal iron oxide nanoparticles (IONPs), functionalized with boron-dipyrromethene (BODIPY) derivatives is described. Optical and relaxometric properties of the nanoparticles have been evaluated, suggesting a potential applicability of the particles as bimodal contrast agent for magnetic resonance and optical imaging. The BODIPY funcionalized IONPs showed bright fluorescence ...

A simple and cost-effective method based on multi-photon microscopy is presented for the preliminary screening of the general morphology, size range and heterogeneity of Ir(III) nano-aggregate formulations.

Self-assembly of cellulose nanocrystals (CNCs) doped with anisotropic gold nanorods (AuNRs) was studied by small-angle neutron scattering. Correlation distances and structured domains were analysed to determine the influence of CNC and AuNR concentration on structuring. The transfer of the nematic structure of CNCs to AuNRs is explained in terms of an entropy-driven evolution from an isotropic to a cholesteric phase, with small nematic domains ...

The supramolecular organization of star-shaped polythiophenes was investigated in a solvent/nonsolvent system and upon cooling. Both systems yield entirely different supramolecular aggregates. Classical characterization techniques can give some insight; the exact mechanism is currently not understood. By introducing second- and third-harmonic light scattering and its combination with other optical techniques, we were able to fully investigate ...

In this study, a new chiral α,ω-bifunctional polythiophene is synthesized and used as a nanoparticle linker molecule to synthesize the first layered conjugated polymer/nanoparticle (CP/NP) hybrid m...

Poly(thiophene)s have an inherently large third-order nonlinear optical (TONO) response, but applications are not straightforward due to unoptimized materials. Therefore, several structure-property relationships (molar mass, branching, regioregularity) are investigated to unravel which structural modifications give the highest TONO response. Poly(3-hexylthiophene) with different molar masses, poly[3-(2-ethylhexyl)thiophene] with different molar ...
