“…The meniscus-guided 3D printing method can also be used to create freeform plasmonic nanoparticle clusters with desired shapes and compositions. Kim et al demonstrated that the 3D geometry of printed quantum dot-embedded plasmonic clusters allowed for radiation pattern manipulation (figure 3(e)), and the plasmonic clusters exhibited enhanced sensitivity for virus detection (figure 3(f)) [52,53]. Thus, such printed plasmonic structures could be used as high-sensitivity, cost-effective pathogen diagnosis platforms, which are in high demand for pandemic management.…”

The continual demand for modern optoelectronics with a high integration degree and customized functions has increased requirements for nanofabrication methods with high resolution, freeform, and mask-free. Meniscus-on-demand three-dimensional (3D) printing is a high-resolution additive manufacturing technique that exploits the ink meniscus formed on a printer nozzle and is suitable for the fabrication of micro/nanoscale 3D architectures. This method can be used for solution-processed 3D patterning of materials at a resolution of up to 100 nm, which provides an excellent platform for fundamental scientific studies and various practical applications. This review presents recent advances in meniscus-on-demand 3D printing, together with historical perspectives and theoretical background on meniscus formation and stability. Moreover, this review highlights the capabilities of meniscus-on-demand 3D printing in terms of printable materials and potential areas of application, such as electronics and photonics.

“…A three-dimensional (3D) electromagnetic Maxwell solver utilizing the finite-difference time-domain method (FDTD) was employed to carry out optical simulations (ANSYS Lumerical FDTD, Canada) [43,44]. A plane wave source was used to illuminate the plasmonic NP -biomaterial thin film nanostructure (surrounded by air (n = 1) on top) with an incident electric field of E0 (see supporting information or SI figure S1).…”

The dynamic and surface manipulation of the M13 bacteriophage meeting application demands enable a pathway to design efficient applications with high selectivity and responsivity rate. Herein, we report the role of the M13 bacteriophage thin film layer deposited on an optical nanostructure involving gold nanoparticles/SiO2/Si and its influence on optical and geometrical properties. The thickness of the M13 phage layer was either controlled by varying the concentration or humidity exposure levels, and optical studies were conducted. We designed a standard and dynamic model based upon three-dimensional finite-difference time-domain (3D FDTD) simulations distinguishing the necessity of each model under variable conditions. As seen from the experiments, the origin of respective peak wavelength positions is addressed in detail with the help of simulations. The importance of the dynamic model was noted when humidity-based experiments were conducted. Inexpensive, multi-wavelength optical characteristics from a single structure, reproducibility, and reversible properties are significant advantages of involving M13 bacteriophage. We believe this work will provide fundamental insight into understanding and interpreting the geometrical and optical properties of the nanostructures involving M13 bacteriophage.

“…[12,33] 3D printing has emerged as a promising manufacturing method for freely designing and realizing freestanding structures. [43,44] Recent studies have demonstrated that highprecision 3D printing techniques based on focused electronbeam-induced deposition [45] or electrohydrodynamic jetting [46] can be utilized to fabricate single-body metallic nanostructures for plasmonic applications. Despite the scientific and technological importance of metamolecule clusters, there is currently no direct printing method available to fabricate freestanding and freeform 3D architectures composed of these clusters with controlled multiple compositions.…”

Metamolecule clusters support various unique types of artificial electromagnetism at optical frequencies. However, the technological challenges regarding the freeform fabrication of freestanding metamolecule clusters with programmed geometries and multiple compositions remain unresolved. Here, the freeform, freestanding raspberry‐like metamolecule (RMM) fibers based on the directional guidance of a femtoliter meniscus are presented, resulting in the evaporative co‐assembly of silica nanoparticles and gold nanoparticles with the aid of 3D nanoprinting. This method offers a facile and universal pathway to shape RMM fibers in 3D, enabling versatile manipulation of near‐ and far‐field characteristics. In particular, the authors demonstrate the ability to decrease the scattering of the millimeter‐scale RMM fiber in visible spectrum. In addition, the influence of electric and magnetic dipole modes on the directional scattering of RMM fibers is investigated. These experiments show that the magnetic response of an individual RMM can be controlled by adjusting the filling factor of gold nanoparticles. The authors anticipate that this method will allow for unrestricted design and realization of nanophotonic structures, surpassing the limitations of conventional fabrication processes.
