Soft Film Nanoimprint Lithography (SMNIL) is an emerging nanomanufacturing technology that excels in achieving precise transfer of nanoscale patterns to substrate materials using flexible films as molds. This versatile technology exhibits promising applications in semiconductors, biopharmaceuticals, and optoelectronics owing to its cost-effectiveness, high resolution, and scalability. In semiconductor manufacturing, SMNIL has notably enhanced chip integration and performance. In biomedicine, it is utilized for fabricating micro-and nanoscale biochips, aiding in disease diagnosis and drug screening. In optoelectronics, SMNIL contributes to the production of optical waveguides, micro/nano gratings, and organic light-emitting diodes (OLEDs), enhancing equipment performance and reducing costs. Despite its advantages, challenges persist in template durability, processing accuracy, and large-scale production for SMNIL. Future developments should focus on enhancing the performance of soft film materials, developing more efficient embossing equipment, and expanding application scopes. SMNIL holds immense potential in the field of nanomanufacturing, and addressing these challenges will further propel its widespread adoption.

“…In another report, a close-packed monolayered polystyrene (PS) sphere array was successfully prepared using the H 2 O 2 -assisted air–water interfacial floating method. The advantage of H 2 O 2 over water is the decreasing number of second-layer defects and the promotion of the self-assembly of PS nanospheres to form a close-packed SAM [ 81 ]. For more details about NSL, readers are referred to a comprehensive review [ 82 ] and other useful research articles [ 83 , 84 ].…”

Noble metal nanostructures are known to confine photon energies to their dimensions with resonant oscillations of their conduction electrons, leading to the ultrahigh enhancement of electromagnetic fields in numerous spectroscopic methods. Of all the possible plasmonic nanomaterials, silver offers the most intriguing properties, such as best field enhancements and tunable resonances in visible-to-near infrared regions. This review highlights the recent developments in silver nanostructured substrates for plasmonic sensing with the main emphasis on surface plasmon resonance (SPR) and surface-enhanced Raman spectroscopy (SERS) over the past decade. The main focus is on the synthesis of silver nanostructured substrates via physical vapor deposition and chemical synthesis routes and their applications in each sensing regime. A comprehensive review of recent literature on various possible silver nanostructures prepared through these methodologies is discussed and critically reviewed for various planar and optical fiber-based substrates.

“…In our study, we fabricate nanocrystals of different shapes and sizes, with different inter-structural gaps and symmetry, along with special (continuous/step-like) variations in thickness, which are resourceful candidates for magnonics/plasmonics research. Our study brings the versatility of the NSL technique, in combination with angled shadow mask deposition, to the next level, opening up the scope for plasmonics [1,[22][23][24][25][26] and magnetics [7,[27][28][29][30].…”

In this article, we present a systematic investigation on a multistep nanosphere lithography technique to uncover its potential in fabricating a wide range of two- and three-dimensional nanostructures. A tilted (polar angle) electron beam shower on a nanosphere mask results in an angled shadow mask deposition. The shape of the shadow also depends on the azimuthal angle of the mask sitting on top of the substrate. We performed angled shadow mask depositions with systematic variation of these two angular parameters, giving rise to complex nanostructures (down to 50 nm), repeated over a large area without defect. In this article, nanosphere lithography with two- and four-fold azimuthal symmetry was studied at constant tilt angles followed by variations in tilt without azimuthal rotation of the substrate. Finally, both angular parameters were simultaneously varied. The structure of shadow crystals was explained using Matlab simulation. This work stretches the horizons of nanosphere lithography, opening up new scopes in plasmonic and magnonic research.
