Porous silicon (PS) can be used as a loading template in sensing or as a matrix to develop nanoparticle arrays. We present a comprehensive study of PS morphology and optical properties before and after the pore opening process, including the determination of thickness, pore size, and pore density of PS layers, its surface wettability, and reflectivity. The PS samples were fabricated by electrochemical anodization of monocrystalline silicon wafer in 5–20 wt.% hydrofluoric acid (HF) solution at a current density in the range of 20–200 mA/cm2. Anodization was followed by the pore opening process, i.e., the removal of a parasitic superficial layer with a “bottleneck” structure by reactive ion etching (RIE). The results illustrate that “bottleneck”-free PS allows to achieve a high pore density using a low HF concentration and a reduced current density. We established that this structure demonstrates higher hydrophobicity in comparison to the samples before RIE. The applicability of the developed “bottleneck”-free PS was tested via filling the pores with silver nanoparticles, indicating its potential use as a template for the fabrication of nanoparticle arrays.

Biosensors have been designed and developed for detecting biomarkers, biomolecules, proteins, enzymes, organisms, and various types of bacterial and viral diseases since the turn of the century. Initially marred by poor sensitivity, specificity, and selectivity, the advent of the notion of photonic biosensors has successfully addressed such drawbacks. One of the hallmarks of modern pharmaceutical industries is the miniaturization of photonic platforms via continuous scaling down of their sizes, which was accomplished by leveraging the concept of artificial media. Numerous forms of photonic and plasmonic devices have been configured for next-generation technologies since the emergence of metamaterials. Among diverse applications, the development of cost-effective, label-free, selective, precise, and on-chip immunobiosensors with rapid sample-to-result feature has received copious interest, recently. This focused Review brings clarity to the rapidly growing body of available and in-development metamaterials-enabled diagnostic instruments based on inventive and promising approaches. Through centering on the operating principles of plasmonic, photonic, and hybrid metasensors, we mechanistically characterize and describe the properties of such tools and summarize the most recent achievements in devising metasensors and bioimaging tools with high precision. This insightful understanding serves as a comprehensive source for scientists, physicians, and students to construct ultradense and high-throughput clinical screening metadevices.

“…[ 29 ] For example, ordered arrays of colloids can be prepared on prepatterned substrates presenting the correct topography using either dip or spin coating setups. Another alternative is represented by capillary‐assisted particle assembly [ 30 ] that takes advantage of the capillary forces generated at the contact line with a receding meniscus. [ 31 ] Although these are all viable approaches for the precise organization of colloidal nanoparticles, template‐assisted self‐assembly emerged as one of the most versatile, especially when combined with nanoimprint lithography, enabling compatibility with roll‐to‐roll fabrication, and adaptability to different colloids, solvents, and surfaces.…”

Ordered arrays of metal nanoparticles offer new opportunities to engineer light–matter interactions through the hybridization of Rayleigh anomalies and localized surface plasmons. The generated surface lattice resonances exhibit much higher quality factors compared to those observed in isolated metal nanostructures. Template‐induced colloidal self‐assembly has already shown a great potential for the scalable fabrication of 2D plasmonic meta‐molecule arrays, but the experimental challenge of controlling optical losses within the repeating units has so far prevented this approach to compete with more standard fabrication methods in the production of high‐quality factor resonances. In this manuscript, the optical properties of plasmonic arrays are investigated by varying the lattice parameter (between 200 and 600 nm) as well as the diameter of the gold colloidal building‐blocks (between 11 ± 1 and 98 ± 6 nm). It is systematically studied how the internal architecture of the repeating gold‐nanoparticle meta‐molecules influences the optical response of the plasmonic supercrystals. Combining both experimental measurements and simulations, it is demonstrated how, reducing the size of the gold nanoparticles it is possible to switch from strong near‐field plasmonic architectures to high‐quality factors (>60) for lattice plasmon resonances located in the visible spectral range.
