Aluminum-Based Hybrid Resists

The cover image illustrates an aluminum-based hybrid resist synthesized by molecular layer deposition and its representative molecular structure. Localized photochemical transformation induced by e-beam and/or EUV exposure leads to selective crosslinking and densification within the resist matrix, forming high-resolution nanopatterns with excellent etch resistance. These features are directly transferred into Si substrates, achieving ultra-high aspect ratio nanostructures for next-generation nanolithography. More details can be found in the Research Article by Jiyoung Kim, Chang-Yong Nam, and co-workers (10.1002/admt.202501639).

Tunable Transdermal Drug Delivery

This cover illustrates a wearable hollow-groove microneedle patch integrated with a refillable spiral reservoir for wirelessly programmable, on-demand drug delivery. Smartphone-controlled pumping drives liquid formulations through microneedles directly into the dermis, enabling precise bolus, pulsatile, or sustained dosing. The system offers a compact, patient-friendly platform for tunable transdermal delivery of therapeutics such as ketamine. More details can be found in the Research Article by Sameer Sonkusale and co-workers (10.1002/admt.202500802).

Biomimetic Magnetic Cilia

In their Research Article (10.1002/admt.202501095), Chenqian Zhang and co-workers propose a quantitative theoretical model that captures the coupled mechanical and magnetic behavior of cilia-based tactile sensors. Representing the cilium as a two-segment beam composed of a non-magnetic base and magnetic tip, the model shows strong agreement with both finite element simulations and experimental results (R² > 0.99).

Multimaterial Microrobots

The cover shows multimaterial microrobots comprising a hard polymer backbone, which enables transportation using optical trapping, and 4D printed sensing elements made of a pH-responsive hydrogel. The sensing elements swell and shrink depending on the local environment, allowing us to estimate local pH from size measurements of the sensing elements. More details can be found in the Research Article by Ada-Ioana Bunea and co-workers (10.1002/admt.202501075).

Artificial Retina Emulators

In their Research Article (10.1002/admt.202501461), Antonella Camaioni, Thomas M. Brown, and co-workers present a liquid/solid biohybrid image sensor inspired by animal retinas that integrates organic semiconductors with a liquid retinal physiological medium. The biocompatible 16-pixel array (micrograph of cells cultured over its surface in the background) converts light into ionic–electronic signals, reproducing the spectral/temporal responses of rod/cone photoreceptors of the retina, and generating real-time color/grayscale images on a display through analog-to-digital conversion, thus bridging living and electronic systems.

Ion-Selective Organic Electrochemical Transistors

In their Research Article (10.1002/admt.202501217) Mainul Hossain, Yasser Khan, and co-workers present an empirical model for ion-selective organic electrochemical transistors (IS-OECTs) that predicts sensitivity and selectivity across varying ion concentrations in biofluids such as sweat. The model captures steady-state behavior in the presence of both target and interfering ions and accurately reproduces concentration-dependent responses, demonstrating strong reliability for advanced electrochemical sensing.

Meta-Holograms

This cover design intuitively shows the replication of the Si master stamp using Ni plating. To compensate for the durability limit of the Si stamp in the nanoimprint lithography process, we propose the fabrication process of the Ni replica stamp. This replicates the metasurfaces of tens of nanoscales with high quality. More details can be found in the Research Article by Heon Lee and co-workers (10.1002/admt.202501486).

Spoof Surface Plasmon Polaritons

This cover includes a spoof surface plasmon polaritons (SSPPs)-based antenna structure in the center, and six antenna technologies with different functions targeting at various application scenarios derived by SSPPs, which are low RCS antennas, beam-reconfigurable antennas, miniaturized antennas, high-gain antennas, HPMP suppressing antennas and holographic antennas, showing the powerful electromagnetic manipulation capabilities of SSPPs. More details can be found in the Review by Hao Chi Zhang and co-workers (10.1002/admt.202501259).
