This paper describes the fabrication of microfluidic devices with a focus on controlling the orientation of photosystem I (PSI) complexes, which directly affects the performance of biophotovoltaic devices by maximizing the efficiency of the extraction of electron/hole pairs from the complexes. The surface chemistry of the electrode on which the complexes assemble plays a critical role in their orientation. We compared the degree of orientation on self-assembled monolayers of phenyl-C61-butyric a...

Unmethylated CpG motifs activate toll-like receptor 9 (TLR9), leading to sequence- and species-specific immune stimulation. Here, we engineered a CpG oligodeoxyribonucleotide (ODN) with multiple hydrophobic moieties, so-called lipid-modified uracil, which resulted in a facile micelle formation of the stimulant. The self-assembled CpG nanostructure (U4CpG) containing the ODN 2216 sequence was characterized by various spectroscopic and microscopic methods together with molecular dynamics simulatio...

Loss aversion can occur in riskless and risky choices. Yet, there is no evidence whether people who are loss averse in riskless choices are also loss averse in risky choices. We measure individual-level loss aversion in riskless choices in an endowment effect experiment by eliciting both WTA and WTP from each of our 360 subjects (randomly selected customers of a car manufacturer). All subjects also participate in a simple lottery choice task which arguably measures loss aversion in risky choices...

Mechanical force applied by ultrasound in solution leads to the dissociation of DNA metallo-base-pair interactions when these motifs are functionalized with oligodeoxynucleotide sequences of sufficient length. The annealing and force-induced denaturing process is followed by the attachment of distance-sensitive fluorescent probes and is found to be reversible.
Zusammenfassung Die Rolle der Polymere in der Pandemiebekampfung sind vielfaltig. Sie reichen von der personlichen Schutzausrustung mit Brillen und Visieren aus Polyethylenterephthalat (PET) und Polycarbonat (PC) uber die Mund-Nasen-Bedeckungen mit inneren Lagen aus feinem, schmelzgeblasenem Polypropylen-Vlies bis hin zu den Abstrichstabchen aus Polystyrol und Nylon oder Viskose, die in der Diagnostik verwendet werden. Die mRNA-Impfstoffe von BioNTech/Pfizer und Moderna, welche die ersten Vakzin...

Enzymes catalyze a vast variety of reactions rendering the regulation of their activity a key method to control biological function. In this work, we report two systems enabling the ultrasound-induced activation of thrombin, which is vital for the coagulation cascade of secondary hemostasis. Firstly, we designed polyaptamers, which can specifically bind to thrombin inhibiting its catalytic activity. With both ultrasound generating inertial cavitation (20 kHz) and therapeutic medical focused ultr...

The development of biomedical glues is an important, yet challenging task as seemingly mutually exclusive properties need to be combined in one material, i.e. strong adhesion and adaption to remodeling processes in healing tissue. Here, we report a biocompatible and biodegradable protein-based adhesive with high adhesion strengths. The maximum strength reaches 16.5 ± 2.2 MPa on hard substrates, which is comparable to that of commercial cyanoacrylate superglue and higher than other protein-based ...

Abstract null null Dynamic DNA-based biomaterials have seen rapid growth with great potential for healthcare and biomedicine. They are notably benefited by programmability, biocompatibility, chemical synthesis/modification, and enzymatic manipulation of nucleic acids. In this review, the molecular basis and resources of DNA-based biomaterials are first summarized. Next, the current state of the art of the construction principles of stimuli-responsive DNA-based biomaterials are classified, predom...
