Summary: The mass fabrication of 3D silicon microstructures with a 100 nm resolution is achieved using scanning probe lithography combined with metal-assisted chemical etching. Various protruding and recessed silicon structures are obtained via different lithography methods, demonstrating applications in nanoimprinting and PDMS stamps. Mass production of arbitrarily shaped silicon microparticles at submicrometer resolution is developed using silicon-on-insulator substrates, with applications in optical microresonators, surface-enhanced Raman scattering templates, and smart microparticles for fluorescence signal coding.

Summary: A new method for fabricating large-area metal and semiconductor nanobridge arrays is proposed in this article, which combines the possibilities offered by nanotransfer printing and UV lithography. The method involves imprinting an array of nanostrips into a resist layer and subsequent UV exposure through an additional mask to define the regions where suspended nanostrip bridges will be formed. Using this method, large-area arrays of Au and Ti/Au nanobridge, as well as SiGe nanobridge arrays, were successfully fabricated. The proposed method is simple, low-cost, and can be implemented on solid and polymer substrates.

Summary: Piezoceramic films, as important energy-conversion materials, face limitations in their application on complex curvilinear surfaces. To overcome this, researchers have developed a new method, called flame treated spray (FTS) coating, which allows the preparation of piezoceramic films on free-form surfaces. This method has been successfully applied in the assembly of highly conformal piezoelectric tactile sensors and on-site thin-film sensors for vibration monitoring.

Summary: This strategy demonstrates a controllable method to fabricate polymeric nanowires with high throughput and low cost using thermal nanoimprint lithography (NIL) technique and self-assembled anodic aluminum oxide (AAO) template. The length of polymeric nanowires can be adjusted by the duration of thermal NIL, and the fill mechanism of thermoplastic intermediate polymer stamp (IPS) into AAO nanopores is essential for the preparation of SERS-active substrates. The approach shows potential for expanding the use of thermal NIL technique and AAO template for fabricating various nanomaterials, especially flexible and transparent polymer-based nanomaterials.

Summary: Gold nanoring arrays with tunable plasmonic resonances can be prepared using colloidal lithography, allowing for flexible control over the dimensions of the nanorings. The plasmonic resonance spectra of the nanoring arrays can be obtained using Fourier transform near-infrared (FT-NIR) absorption spectroscopy. The prepared gold nanoring arrays exhibit a strong MR or IR plasmonic resonance which can be tuned by varying the nanoring dimensions, with potential applications in surface-enhanced spectroscopy or plasmonic sensing.
