text: DNA origami nanostructures are a powerful tool in biomedicine and
can be used to combat drug‐resistant bacterial infections. However, the effect
of unmodified DNA origami nanostructures on bacteria is yet to be elucidated.
With the aim to obtain a better understanding of this phenomenon, the effect of
three DNA origami shapes, i.e., DNA origami triangles, six‐helix bundles (6HBs),
and 24‐helix bundles (24HBs), on the growth of Gram‐negative Escherichia coli
and Gram‐positive Bacillus subtilis is investigated. These results reveal that
while triangles and 24HBs can be used as a source of nutrients by E. coli and
thereby promote population growth, their effect is much smaller than that of genomic
single‐ and double‐stranded DNA. However, no effect on E. coli population growth
is observed for the 6HBs. On the other hand, B. subtilis does not show any significant
changes in population growth when cultured with the different DNA origami shapes
or genomic DNA. The detailed effect of DNA origami nanostructures on bacterial
growth thus depends on the competence signals and uptake mechanism of each bacterial
species, as well as the DNA origami shape. This should be considered in the development
of antimicrobial DNA origami nanostructures.

text: DNA origami nanostructures (DONs) are able to scavenge reactive oxygen
species (ROS) and their scavenging efficiency toward ROS radicals was shown to
be comparable to that of genomic DNA. Herein, we demonstrate that DONs are highly
efficient singlet oxygen quenchers outperforming double‐stranded (ds) DNA by several
orders of magnitude. To this end, a ROS mixture rich in singlet oxygen is generated
by light irradiation of the photosensitizer methylene blue and its cytotoxic effect
on Escherichia coli cells is quantified in the presence and absence of DONs. DONs
are found to be vastly superior to dsDNA in protecting the bacteria from ROS‐induced
damage and even surpass established ROS scavengers. At a concentration of 15 nM,
DONs are about 50 000 times more efficient ROS scavengers than dsDNA at an equivalent
concentration. This is attributed to the dominant role of singlet oxygen, which
has a long diffusion length and reacts specifically with guanine. The dense packing
of the available guanines into the small volume of the DON increases the overall
quenching probability compared to a linear dsDNA with the same number of base
pairs. DONs thus have great potential to alleviate oxidative stress caused by
singlet oxygen in diverse therapeutic settings.

text: DNA origami nanostructures are promising carries for drug delivery
applications. However, their limited stability under relevant conditions often
presents a challenge. Herein, the structural stability of DNA origami nanostructures
is investigated in a setting compatible with their application in photodynamic
therapy (PDT). To this end, DNA origami triangles and six‐helix bundles (6HBs)
are loaded with the clinically tested photosensitizer methylene blue, which upon
irradiation with red light generates reactive oxygen species (ROS) that attack
the DNA origami nanostructures. ROS‐induced structural damage is observed to depend
on the ionic composition of the surrounding medium and becomes more severe at
low ionic strength. Mg2+ ions can efficiently protect the
DNA origami nanostructures from ROS‐induced damage and may even heal some of the
damage obtained under Mg2+‐free conditions when added after
irradiation. Finally, the employed DNA origami 6HBs are more resistant toward
ROS‐induced structural damage than the triangles, which is attributed to their
markedly different mechanical properties. These results thus provide some fundamental
insights into the stabilizing role of DNA origami superstructure that may guide
the selection or design of DNA origami nanocarriers with optimized stability for
their application in PDT.

text: AbstractDue to its excellent biocompatibility,
pure iron is a very promising implant material, but often features corrosion rates
that are too low. Using additive manufacturing and modified powders the microstructure
and, thus, the material properties, e.g., the corrosion properties, can be tailored
for specific applications. Within the scope of this study, pure iron powder was
modified with different amounts of CeO2 or Fe2O3
nanoparticles and subsequently processed by Electron Beam Powder Bed Fusion (PBF-EB/M).
The corrosion-fatigue behavior of CeO2 and Fe2O3
modified iron was investigated using rotation bending tests under the influence
of simulated body fluid (m-SBF). While the modification using Fe2O3
showed reduced fatigue and corrosion-fatigue strengths, it could be demonstrated
that the modification with CeO2 is characterized by improved
fatigue properties. The superior fatigue properties in air are attributed to the
positive impact of dispersion strengthening. Additionally, an increased degradation
rate compared to pure iron could be observed, eventually promoting an earlier
failure of the specimens in the corrosion fatigue tests.

text: AbstractNanostructured bilayer thin films
with superhydrophobic and superhydrophilic surfaces were prepared using Ti6Al4V
alloy substrates which allowed for the comparative analysis of polyvinyl acetate
(PVAc) particle adsorption as a function of the interface structure. The PVAc
particles were obtained from emulsion polymerization of vinyl acetate. A superhydrophilic
TiO2 nanofiber-based 3D network was created on the Ti6Al4V
alloy substrate by application of a hydrothermal method. Subsequent UV-grafting
of ultra-thin polydimethylsiloxane (PDMS) layers resulted in a superhydrophobic
surface. The modification steps were followed via Diffuse Reflectance Infrared
Fourier Transform Spectroscopy, X-ray Photoelectron Spectroscopy, Field Emission-Scanning
Electron Microscopy, contact angle and Electrochemical Impedance Spectroscopy.
A mechanism for the adsorption of PVAc at the two electrolyte/substrate interfaces
could be revealed.

text: Bacterial colonization and biofilm formation on abiotic surfaces are
initiated by the adhesion of peptides and proteins. Understanding the adhesion
of such peptides and proteins at a molecular level thus represents an important
step toward controlling and suppressing biofilm formation on technological and
medical materials. This study investigates the molecular adhesion of a pilus‐derived
peptide that facilitates biofilm formation of Pseudomonas aeruginosa, a multidrug‐resistant
opportunistic pathogen frequently encountered in healthcare settings. Single‐molecule
force spectroscopy (SMFS) was performed on chemically etched ZnO surfaces to gather
insights about peptide adsorption force and its kinetics. Metal‐free click chemistry
for the fabrication of peptide‐terminated SMFS cantilevers was performed on amine‐terminated
gold cantilevers and verified by X‐ray photoelectron spectroscopy (XPS) and polarization‐modulated
infrared reflection absorption spectroscopy (PM‐IRRAS). Atomic force microscopy
(AFM) and XPS analyses reveal stable topographies and surface chemistries of the
substrates that are not affected by SMFS. Rupture events described by the worm‐like
chain model (WLC) up to 600 pN were detected for the non‐polar ZnO(11‐20) surfaces.
The dissociation barrier energy at zero force ΔG(0), the transition state distance
xb and bound‐unbound dissociation rate at zero force koff(0) for the single crystalline
substrate indicate that coordination and hydrogen bonds dominate the peptide/surface
interaction.

text: This article presents the potential-dependent adsorption of two proteins,
bovine serum albumin (BSA) and lysozyme (LYZ), on Ti6Al4V alloy at pH 7.4 and
37 °C. The adsorption process was studied on an electropolished alloy under cathodic
and anodic overpotentials, compared to the open circuit potential (OCP). To analyze
the adsorption process, various complementary interface analytical techniques
were employed, including PM-IRRAS (polarization-modulation infrared reflection-absorption
spectroscopy), AFM (atomic force microscopy), XPS (X-ray photoelectron spectroscopy),
and E-QCM (electrochemical quartz crystal microbalance) measurements. The polarization
experiments were conducted within a potential range where charging of the electric
double layer dominates, and Faradaic currents can be disregarded. The findings
highlight the significant influence of the interfacial charge distribution on
the adsorption of BSA and LYZ onto the alloy surface. Furthermore, electrochemical
analysis of the protein layers formed under applied overpotentials demonstrated
improved corrosion protection properties. These studies provide valuable insights
into protein adsorption on titanium alloys under physiological conditions, characterized
by varying potentials of the passive alloy.

text: Multiprotein adsorption from complex body fluids represents a highly
important and complicated phenomenon in medicine. In this work, multiprotein adsorption
from diluted human serum at gold and oxidized iron surfaces is investigated at
different serum concentrations and pH values. Adsorption-induced changes in surface
topography and the total amount of adsorbed proteins are quantified by atomic
force microscopy (AFM) and polarization-modulation infrared reflection absorption
spectroscopy (PM-IRRAS), respectively. For both surfaces, stronger protein adsorption
is observed at pH 6 compared to pH 7 and pH 8. PM-IRRAS furthermore provides some
qualitative insights into the pH-dependent alterations in the composition of the
adsorbed multiprotein films. Changes in the amide II/amide I band area ratio and
in particular side-chain IR absorption suggest that the increased adsorption at
pH 6 is accompanied by a change in protein film composition. Presumably, this
is mostly driven by the adsorption of human serum albumin, which at pH 6 adsorbs
more readily and thereby replaces other proteins with lower surface affinities
in the resulting multiprotein film.

text: The influence of nanoscale surface topography on protein adsorption
is highly important for numerous applications in medicine and technology. Herein,
ferritin adsorption at flat and nanofaceted, single-crystalline Al2O3 surfaces
is investigated using atomic force microscopy and X-ray photoelectron spectroscopy.
The nanofaceted surfaces are generated by the thermal annealing of Al2O3 wafers
at temperatures above 1000 °C, which leads to the formation of faceted saw-tooth-like
surface topographies with periodicities of about 160 nm and amplitudes of about
15 nm. Ferritin adsorption at these nanofaceted surfaces is notably suppressed
compared to the flat surface at a concentration of 10 mg/mL, which is attributed
to lower adsorption affinities of the newly formed facets. Consequently, adsorption
is restricted mostly to the pattern grooves, where the proteins can maximize their
contact area with the surface. However, this effect depends on the protein concentration,
with an inverse trend being observed at 30 mg/mL. Furthermore, different ferritin
adsorption behavior is observed at topographically similar nanofacet patterns
fabricated at different annealing temperatures and attributed to different step
and kink densities. These results demonstrate that while protein adsorption at
solid surfaces can be notably affected by nanofacet patterns, fine-tuning protein
adsorption in this way requires the precise control of facet properties.
