Cy3-labeled LNA–miRNA gold nanoprobes are physically adsorbed onto MoS₂ nanosheets via sulfur vacancies and edge sites. Upon laser excitation, plasmonic gold nanoparticles amplify Raman scattering, yielding sharp Cy3-spectral peaks that reveal precise probe functionalization and sensitive miRNA detection.

Micro- and Nanostructured Surfaces

This cover highlights the multifunctional behaviors of nano- and microstructured surfaces. By focusing on microcavity-based reentrant and hierarchical architectures, the design emphasizes liquid repellency as the fundamental property that enables anti-icing and antimicrobial functions. The visual metaphor illustrates how structural engineering at multiple scales creates surfaces that not only repel liquids but also provide robust protection against environmental and biological challenges.

Dental implants are the standard for replacing missing teeth, with the Ti-6Al-4V alloy dominating the market due to its superior osteointegration. However, long-term implant success is often hindered by peri-implantitis, which stems from bacterial colonization and biofilm formation. To address this challenge, titanium-copper (Ti-Cu) alloys garner attention for their dual antibacterial and osteogenic properties. This review organizes and explores the antibacterial mechanisms of Ti-Cu alloys and their role in promoting osteogenesis in comparison to conventional alloys. Key findings from existing literature underscore the potential of Ti-Cu alloys to enhance implant performance and longevity. Although the literature is promising, further research is needed to determine optimal composition ranges that balance biocompatibility, mitigate cytotoxicity from copper ion release, and facilitate clinical translation. Ti-Cu alloys represent a transformative approach to improving implant outcomes and addressing the limitations of current materials.

Efficient charge transfer at heterostructure interfaces is crucial for optoelectronic devices. Quasi-2D perovskites with varied layer thicknesses form multiple interfaces, hindering transport. Transient absorption spectroscopy reveals strategic phase distribution enables ultrafast energy transfer across phases and narrow-band emission from high-n phases. Photocurrent and surface potential change indicates directional charge transport exhibits in Quasi-2D perovskites, underscoring the impact of phase distribution on device performance. More details can be found in the Research Article by Sachin R. Rondiya and co-workers (DOI: 10.1002/admi.202500108).

Silicon-based negative electrodes are essential for next-generation high-capacity Li-ion batteries, with SiO₂ emerging as a promising and sustainable option. However, SiO₂ anodes have limited cycling stability, which can be improved by tailoring the solid electrolyte interphase (SEI) through electrolyte engineering. This study investigates the effects of LiPF₆ and LiFSI electrolyte salts, along with fluoroethylene carbonate (FEC) and vinylene carbonate (VC) additives, on the performance of SiO₂ anodes. Galvanostatic cycling and electrochemical impedance spectroscopy (EIS) are combined with SEI composition analysis using Ar⁺-sputtered X-ray photoelectron spectroscopy and hard X-ray synchrotron photoelectron spectroscopy at different photon energies. The results show that FEC enhances capacity retention, while VC improves long-term stability at the expense of lower initial capacity. No synergistic benefits are observed from combination of both additives. LiFSI-based electrolytes deliver high initial capacities but suffer capacity fade over cycling, whereas additive-free LiPF₆ formulations lead to poor cycling stability due to the formation of a thick and resistive SEI layer. In contrast, LiFSI promotes a thinner and more inorganic-rich SEI. Both FEC and VC lead to the formation of a poly(VC) surface layer that enhances capacity retention. The FEC-derived layer, enriched with LiF and thinner in nature, exhibits improved SEI stability. These findings provide valuable insights for designing electrolytes to improve the cycling performance of SiO₂ anodes.

Ru₃Sn₇ is experimentally demonstrated as an efficient catalyst, with potential utilization of topological surface states for hydrogen evolution reaction. Despite its promising catalytic performance, the topological nature of Ru₃Sn₇ remains uncertain. Particularly, the bulk-boundary correspondence has not yet been established, hence hindering a rigorous justification of its topologically-protected surface states. In this work, the bulk topology of Ru₃Sn₇ is detailed using first-principles calculations and the topological quantum chemistry formalism. Ru₃Sn₇ turns out to be an enforced semimetal possessing symmetry-protected crossings within a set of bands near the Fermi level, which are enforced and prescribed by the violations of symmetry-prescribed compatibility relations. Moreover, the surface states and the associated origin from the same set of entangled bands are identified, thereby establishing the bulk-boundary correspondence. To evaluate the effects of chemical modifications, the response of topological surface states to various surface terminations, stoichiometry, and oxidation is examined. The surface structures are globally optimized, and the phase diagrams for various experimental conditions are built. It is shown that, due to changes in the local chemical environment, the original surface states are significantly altered. Modified surface bands can be observed near the Fermi level on surface terminations that preserve the C_4v symmetry.

Surface functionalization is essential for improving polymer properties like wettability and wear resistance. Polydimethylsiloxane (PDMS) is widely used due to its flexibility, biocompatibility and ease of fabrication. Soft lithography—based on molding and replication—is the most common approach to tailor its wettability, but producing high-quality molds remains complex and time-consuming, calling for faster, cost-effective and reproducible alternatives. In this work, a novel femtosecond laser-based technique is presented for the rapid and precise fabrication of aluminum molds for PDMS replication. By tuning hatch distance and scan number as key process parameters, the resulting surface morphology of the PDMS replicas is controlled. The samples are characterized morphologically and by profilometry; the reproducibility of the laser-engraved molds and the effect on the final PDMS surfaces is assessed, alongside wettability measurements as a function of the processing parameters, achieving superhydrophobic behavior under optimized conditions. Long-term testing over 4 months confirmed the stability and durability of the surface properties, highlighting their potential for applications in self-cleaning systems, droplet-based microfluidics and biomedical devices.

Surface design aimed at regulating the behavior of endothelial cells is currently a key research direction in cardiovascular interventional/implantable materials. This review focuses on three primary regulatory strategies in material biology: direct regulation, protein-mediated regulation, and biological factor regulation. These strategies aim to promote the recovery of endothelial cell function by optimizing the interaction between materials and blood, cells, and tissues. Furthermore, these surfaces also exhibit diverse effects in vivo on different types of cells. It is precisely due to the complex factors and diverse effects in the pathological environment that these macro-to-micro regulation strategies exhibit opposing states on the material-tissue efficacy interface. Therefore, this series of design ideas still faces challenges in practical applications, including time-sequential functional changes after implantation, how to maintain protein activity in complex pathological environments, and how to accurately control the release of biological factors. The study concludes by emphasizing that the endothelialization surface modification of stent materials is moving towards multidimensionality, including exploring the synergistic effects of these strategies and how to achieve optimal therapeutic outcomes under various pathological conditions, in order to develop more effective and safer vascular stent materials and provide new solutions for the treatment of cardiovascular diseases.
