                  <jats:p>Lithographic surface patterning is a cornerstone of modern materials and device fabrication. Although the available lithography techniques are constantly being advanced to push the feature sizes down to the few-nanometer scale, such developments are associated with many technological and economic challenges. Combining established top-down lithography with bottom-up self-assembly strategies has the potential to overcome those challenges and enable the manipulation of matter with molecular precision. One of the most exciting approaches in this regard is to harness the programmability of DNA self-assembly to create precise DNA nanostructure masks to be used in the lithographic patterning of diverse substrates. DNA nanotechnology has provided us with a versatile toolbox for the high-yield synthesis of 2D and 3D nanostructures with complex, user-defined shapes at unprecedented molecular accuracy. Consequently, the last decade has seen intense research efforts aimed at transferring such DNA nanostructure shapes into functional organic and inorganic materials and we have now arrived at a point where sophisticated molecular lithography approaches utilize DNA nanostructure masks for the fabrication of plasmonic surfaces for metamaterials and sensing applications. This review summarizes how the spatial information of such DNA nanostructure masks can be transferred into various organic and inorganic materials through selective etching and deposition steps. The review also discusses recent developments toward all-purpose molecular lithography schemes and highlights promising extensions of the discussed methods toward new materials systems and application fields.</jats:p>}},

In this work, we investigate the impact of the optical pulse shape and duration on the accuracy of this method. We find that Gaussian temporal pulse shapes yield cleaner arrival-time histograms and, thus, more accurate PNR, compared to bandpass-filtered pulses of equal bandwidth. For low system jitter and an optical pulse duration comparable to the other jitter contributions, photon numbers can be discriminated in our system with a commercial SNSPD. At 60 ps optical pulse duration, photon-number discrimination is significantly reduced. Furthermore, we highlight the importance of using the correct arrival-time histogram model when analyzing photon-number assignment. Using exponentially modified Gaussian distributions, instead of the commonly used Gaussian distributions, we can more accurately determine photon-number misidentification probabilities. Finally, we reconstruct the positive operator-valued measures of the detector, revealing sharp features that indicate the intrinsic PNR capabilities.</jats:p>}},

                  <jats:p>Social media is integral to adolescents’ daily lives and plays an important role in their health- and fitness-related behavior, particularly through trends such as #fitspiration, a portmanteau of “fit” and “inspiration.” This trend has become a prominent aspect of adolescents’ fitness culture. Empirical studies demonstrate that while #fitspiration holds the potential to motivate adolescents to be physically active, it also perpetuates gender-stereotyped, predominantly White, ableist, and normative body ideals associated with fitness and an idealized weight. This trend can be linked to an increased risk of body image concerns or disordered eating among adolescents. Understanding adolescents’ engagement with fitspiration content is crucial for tailoring health and media literacy education within physical education. Therefore, a systematic review of qualitative and quantitative studies was conducted. A search of five electronic databases yielded 312 abstracts, of which 12 met the inclusion criteria. The analysis of the selected studies was based on thematic analysis and included both primary and secondary data. Seven analytical themes emerged: (1) 37–56% of adolescents actively engage with fitspiration content on social media; (2) it fulfills their need for informal and accessible participation; (3) it fosters a sense of social connection; (4) they derive inspiration from peers and influencers; (5) they aspire to idealized body standards; (6) they seek quick solutions when dissatisfied with their bodies; and (7) a few become demotivated and critical when unable to achieve these ideals. Consequently, educators should balance the potential benefits with media literacy interventions to mitigate risks such as body image issues and eating disorders.</jats:p>}},

However, optical networks constructed from conventional bulk 2 × 2-beamsplitters encounter inherent scalability issues, as the number of required beamsplitters scales quadratically with the number of optical modes for a fully connected network. Metasurfaces offer a promising route to
overcome these constraints. By manipulating light at the wavelength scale, compact optical components with advanced functionalities can be constructed, which address several modes simultaneously. In this work, we design and experimentally utilize a metasurface as a multiport beamsplitter. Furthermore, we realized a multimode interferometer composed of two cascaded metasurfaces. We characterize the individual and cascaded metasurfaces by using classical light, showing controllable splitting ratios through tunable phase relations. We then expand the approach to quantum light, employing single photons to demonstrate second- and third-order photon correlations as well as single photon interference across multiple spatial paths. These results establish metasurface-based multiport beamsplitters as a scalable and reconfigurable platform bridging classical and quantum photonics. }},

  abstract     = {{Metasurfaces are powerful tools for manipulating light using small structures on the nanoscale. In most metasurfaces, near-field couplings are treated as being unfavorable perturbations. Here, we experimentally investigate a structure consisting of sinusoidally modulated silicon waveguides where near-field coupling of local resonances leads to negative coupling, i.e., a negative coupling constant. This gives rise to wave-vector-dependent eigenstates of elliptical, linear, and circular polarizations. In particular, fully circular polarization states are not only present at a single point in momentum space (k-space) but also along a line. This circular polarization line, as well as a linear polarization line, emanates from a polarization degeneracy at the Dirac point. We experimentally validate the existence of these eigenstates and demonstrate the energy-, polarization-, and wave vector dependence of this metasurface as well as its sensitivity to fabrication tolerances. By tuning the incident k-vector, certain polarization-energy eigenstates are strongly reflected, allowing for uses in angle-tunable polarization filters and light sources.}},

  abstract     = {{<jats:p>In recent years, nanostructures assembled by DNA have found promising applications in optics, medicine, and sensing. DNA origami in particular provides unique self‐assembly properties, not only enabling a vast variety of functionalization schemes but also presenting a promising route to fabricate large‐scale, bottom‐up nanostructured arrays. This approach has comparable precision to electron beam lithography but avoids slow and expensive patterning steps. However, self‐assembly of lattices with high order and well‐defined periodicity requires careful tuning of the deposition parameters and interactions involved, which has been done mostly on mica so far. As mica is not compatible with standard microfabrication processes, we investigate here the assembly of DNA origami lattices on the most general microfabrication material, that is, silicon wafers, which has turned out to be rather challenging. We study how the forming of polycrystalline 2D‐fishnet‐type lattices is influenced by different incubation conditions and strengths of the origami–origami and origami‐surface interactions, with the aim to create large‐scale single‐crystalline lattices. The lattices are characterized by atomic force microscopy and analyzed for precision of formation, achievable domain size, and surface coverage of well‐formed lattices. Thanks to the silicon substrate, these DNA origami lattices can be further combined with traditional microfabrication processes to turn them, for example, into metamaterials with novel optical properties.</jats:p>}},

                  <jats:p>Ligation of staple strands in DNA origami nanostructures (DONs) can yield enhanced structural stability in critical environments. This process can be viewed as performing hundreds of parallel reactions programmed on a self‐assembled nanoscale platform. While previous studies have focused on investigating the collective results of the chemical or enzymatic ligation reactions, herein, the global quantitative analysis of individual ligation reactions is achieved using quantitative PCR (qPCR). By mapping enzymatic ligation efficiency on a trapezoidal substructure representing one‐third of a triangular DON, ligation is shown to preferentially occur at the trapezoid edges rather than at inner sites. Excellent agreement between the experimental ligation yields and docking simulations suggests that this is a result of variations in the ligase docking probability. Ligation products involving more than two consecutive sequences can be generated with each enzyme‐catalyzed reaction as an independent event. Interestingly, the sharp contrast between the edges vs. the inner sites has been abolished by changing the reaction conditions and performing the ligation in a DMSO co‐solvent system. This analytic method provides unprecedented insight into the multiple ligation reactions occurring in parallel within complex DONs and will be an invaluable tool in the translation of DONs from the lab to real‐world applications.</jats:p>}},

  abstract     = {{Over the past decades, nanoparticulate drug carrier systems have emerged as promising tools in medicine. A persistent challenge in current pharmacotherapy is the limited selectivity of active pharmaceutical ingredients, resulting in undesirable side effects. Smart drug delivery systems, which release encapsulated active pharmaceutical ingredients in response to specific stimuli, offer a potential solution by enabling controlled drug release. This approach can be particularly relevant for exploiting biochemical differences between extracellular and intracellular environments. In this study, self-immolative polydisulfide based polymers manufactured from dithiothreitol were processed into nanoparticle formulations to respond preferentially to elevated glutathione levels, which are characteristic of intracellular environments and are often increased in tumor cells. The influence of polymer chain length on the physicochemical properties of the resulting nanoparticles was investigated. Lumogen® Red was incorporated as a model substance to determine the loading capacity of the carrier system. Degradation was characterized using dynamic light scattering and asymmetric flow field-flow fractionation, as well as by imaging techniques such as atomic force microscopy. Selective release of the embedded substance was demonstrated at elevated glutathione concentrations, while no significant release was observed at extracellularly relevant levels (10 µM glutathione), where the behavior was comparable to the buffer control. Increased release was observed under intracellularly relevant conditions (2 – 10 mM glutathione). These findings support a redox-responsive behavior under intracellular-like conditions. The latter was proven for primary fibroblasts and the cancer cell lines BT-474, MCF-7 and SK-BR-3 by quantification of intracellular low molecular weight thiols. The nanoparticle uptake was confirmed in the investigated cell lines by visualization via confocal laser scanning microscopy. Via lysosomal staining it was shown that nanoparticles accumulate in lysosomes. Furthermore, the carrier system itself showed no cytotoxic properties in cell culture studies against the four different cell types. The developed system is a suitable and very promising smart drug delivery system in the context of controlled drug release.}},
