text: The specific binding of DNA origami nanostructures (DONs) to bacteria
is an important prerequisite for their application in pathogen targeting and antimicrobial
drug delivery. So far, targeting bacteria with DONs has been achieved exclusively
via aptamers, which suffer from drawbacks such as sensitivity toward environmental
conditions and reduced binding after immobilization or conjugation. Here, an alternative
approach is presented based on the modification of DONs with the cell wall‐binding
glycopeptide antibiotic vancomycin. Using strain‐promoted azide‐alkyne cycloaddition,
azide‐modified vancomycin is conjugated to selected staple strands and subsequently
incorporated into 2D DON triangles. The resulting constructs show specific binding
to the Gram‐positive species Bacillus subtilis (B.
subtilis) and Staphylococcus capitis
(S. capitis), and remarkably, to Gram‐negative Escherichia
coli (E. coli), but no antimicrobial
activity at vancomycin concentrations up to at least 2.91 μM. For B.
subtilis and E. coli, DONs with vancomycin
modifications on both sides exhibit better binding than DONs modified on only
one side. However, both variants bind equally well to S. capitis.
These results demonstrate the great potential of small molecule drug compounds
for the robust, broad‐spectrum targeting of bacteria with DONs. Targeting a ubiquitous
cell wall component of most pathogenic bacteria, vancomycin‐modified DONs have
many potential applications in the prevention and treatment of nosocomial infections.

text: AbstractControlling the surface orientation
of DNA origami nanostructures (DON) is crucial for applications in nanotechnology
and materials science. While previous work utilized various DON modifications,
simple methods for controlling their landing orientation remain scarce. Here,
we demonstrate a straightforward approach to control the adsorption orientation
of chiral double‐L (CDL) DON on mica by tuning magnesium ion (Mg2⁺)
concentration and exploiting global shape distortions. Using atomic force microscopy
(AFM), we analyzed the resulting distribution of the mirror‐image orientations,
referred to as S and Z orientations, at both buffer/mica and air/mica interfaces
and identified conditions resulting in homogenous CDL orientation of 100% S. These
results demonstrate how DON conformation and ionic environments influence DON
orientation, offering insights for precise nanostructure deposition.

text: We investigated electrodeposited nanoparticulate nickel selenide (pre)catalysts
that transform into nickel oxides/oxyhydroxides under oxygen evolution reaction
conditions in alkaline solutions. Previous studies of this transformation were
conducted at lower current densities than those of industrial relevance (≥1 A
cm–2). We used ultramicroelectrodes (UMEs) to achieve such current densities,
benefiting from their small size, ensuring low absolute currents and low ohmic
drop but high current densities. Morphological degradation of the catalyst material
was only observed at current densities exceeding 1 A cm–2 but not for smaller
ones. Using X-ray absorption, X-ray photoemission spectroscopy, and X-ray diffraction,
we confirmed that the degradation was accompanied by the literature-known transformation
of nanoparticulate Ni3Se2 (bulk)/NiSe (surface) into nickel oxyhydroxide. The
transformation of the precatalyst goes along with a significant improvement in
the charge transfer kinetics observed by decreasing Tafel slopes with ongoing
experimental time extracted from cyclic voltammetry (CV) experiments and electrochemical
impedance spectroscopy (EIS) in the high-frequency range. However, these kinetic
improvements are accompanied by limitations in mass transport concluded from decreasing
current responses at high overpotentials in CVs and increasing impedance in the
low-frequency range of the EIS spectra after extended CV cycling. These mass transport
limitations originated from morphological degradations at the UME exceeding 1
A cm–2 which we proved by applying identical location scanning electron microscopy.
This has not been reported in studies that have been limited to lower current
densities before. Our findings showcase how UMEs can be used to study (pre)catalysts
(herein nickel selenides) under current densities of industrial relevance in the
absence of ohmic drop-related ambiguities, combined with in-depth materials characterization
studies, e.g., identical location microscopy and advanced spectroscopic methods.
This approach enables direct evaluation and comparison of catalyst materials and
thus demonstrates how to overcome long-standing limitations of electrocatalyst
design and testing.

text: "ABSTRACT\r\n Spin‐coated
polylactide (PLA) thin films were exposed to nitrogen plasma for varying time
intervals. The progressive etching of the PLA film in direct contact with the
nitrogen plasma was monitored in situ using polarization modulated infrared reflection
absorption spectroscopy (PM‐IRRAS). No appreciative changes in composition were
seen with PM‐IRRAS, indicating that the etching did not significantly affect the
bulk composition. Atomic force microscopy characterization of the plasma‐etched
films showed that the PLA films are homogeneously etched. Subsequent ex situ XPS
analysis of the treated surface revealed the presence of C‐N bonds in the surface‐near
region that could be associated with amino and/or amide surface species. PLA films
were also alternatively exposed to nitrogen ion beams produced by an electron‐cyclotron‐resonance
(ECR) plasma source and were investigated in vacuo by XPS. This treatment revealed
the partial substitution of surface oxygen species by nitrogen, resulting in a
similar surface modification as in the plasma case. The comparison of XPS data
and water contact angle studies suggest that the activated surfaces show a reorientation
of macromolecular fragments in the surface‐near region depending on the polarity
of the phase with which they are in contact. Under ultra‐high vacuum (UHV) conditions,
the surface tends to lower its surface energy, while in contact with the aqueous
phase, subsurface polar groups orientate outwards, which enables the formation
of hydrogen bonds."

text: Doped Co3O4 nanoparticles are investigated via spectro-electrochemistry in
the (pre-) oxygen evolution reaction (OER) regime by tracing the absorption signal
of the Co3+ d–d transition under applied bias for getting insight into the catalysts
activation and the formation of catalytically active phases. In the low potential
regime up to 1.37 VRHE, a rise in the optical absorption signal of the [Co3+]oct
d–d transition is observed and attributed to a structural change from [Co2+]tet
to [Co3+]oct due to an electrochemically induced surface restructuring with water.
For applied potentials higher than 1.37 VRHE an overall offset of the absorption
spectra in the UV–vis range, equivalent to a darkening of the materials is detected.
This is attributed to the formation of a CoOx(OH)y skin layer as supported by
high-energy X-ray diffraction (HE-XRD) measurements. We found that the kinetics
of the Co3+ states are heavily influenced by the type of dopant with V-doped Co3O4
exhibiting stable Co3+ states (>20 min) while the Mn-doped Co3O4 Co3+ states reduce
within 36 s under reductive bias. We conclude that doping Co3O4 with transition
metals affects the formation and potential-dependent thickness of the CoOx(OH)y
skin layer as the catalytically active phase and the formation of long-time stable
surface Co3+ states after activation in the first OER cycle.

text: ABSTRACTSpin‐coated polylactide (PLA) thin
films were exposed to nitrogen plasma for varying time intervals. The progressive
etching of the PLA film in direct contact with the nitrogen plasma was monitored
in situ using polarization modulated infrared reflection absorption spectroscopy
(PM‐IRRAS). No appreciative changes in composition were seen with PM‐IRRAS, indicating
that the etching did not significantly affect the bulk composition. Atomic force
microscopy characterization of the plasma‐etched films showed that the PLA films
are homogeneously etched. Subsequent ex situ XPS analysis of the treated surface
revealed the presence of C‐N bonds in the surface‐near region that could be associated
with amino and/or amide surface species. PLA films were also alternatively exposed
to nitrogen ion beams produced by an electron‐cyclotron‐resonance (ECR) plasma
source and were investigated in vacuo by XPS. This treatment revealed the partial
substitution of surface oxygen species by nitrogen, resulting in a similar surface
modification as in the plasma case. The comparison of XPS data and water contact
angle studies suggest that the activated surfaces show a reorientation of macromolecular
fragments in the surface‐near region depending on the polarity of the phase with
which they are in contact. Under ultra‐high vacuum (UHV) conditions, the surface
tends to lower its surface energy, while in contact with the aqueous phase, subsurface
polar groups orientate outwards, which enables the formation of hydrogen bonds.

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.
