“…Significant progress has been achieved in controlling the morphology, size, composition and doping, on length scales ranging from the atomic regime to larger dimensions. The synthesis of SiNW structures is generally categorized into two distinct but equally important approaches: top‐down and bottom‐up 26, 27. In this section, we focus on the metal‐assisted solution etching as a representative method for the top‐down approach, and the metal‐catalyzed VLS‐growth as a representative method for the bottom up approach, as most of the biological and energy applications discussed later in this review are based on SiNWs formed by these two methods.…”

Semiconducting silicon nanowires (SiNWs) represent one of the most interesting research directions in nanoscience and nanotechnology, with capabilities of realizing structural and functional complexity through rational design and synthesis. The exquisite control of chemical composition, structure, morphology, doping, and assembly of SiNWs, in both individual and array format, as well as incorporation with other materials, offers a nanoscale building block with unique electronic, optoelectronic, and catalytic properties, thus allowing for a variety of exciting opportunities in the fields of life sciences and renewable energy. This review provides a brief summary of SiNW research in the past decade, from the SiNW synthesis by both the top-down approaches and the bottom-up approaches, to several important biological and energy applications including biomolecule sensing, interfacing with cells and tissues, lithium-ion batteries, solar cells, and photoelectrochemical conversion.

Nanowires have a wide variety of biomedical applications, including drug delivery, cellular manipulation, cellular interfacing, and biosensing. Specifically, hollow nanowire arrays, or “nanostraws,” are recently developed to penetrate cell membranes and to provide temporal and dose controlled delivery of biomolecules into the cells. The fabrication of nanostraw arrays uses nanoporous membranes as starting templates. However, nanoporous membranes with custom‐designed diameters and densities are often expensive or commercially unavailable. As a result, nanostraws reported in literature consist of a limited number of structures with restricted applications. In this work, a simple approach of preparing nanostraws with differing structures, including various diameters, lengths, and densities, is developed. Furthermore, the application of nanostraws in gene transfection is assessed. To fabricate the nanostraw arrays, O2 plasma etching is applied to the template membrane with a desirable pore density to produce nanopores with matching sizes. Then, a series of nanostraws with controllable diameters, densities, and lengths is consistently fabricated. Finally, the nanostraws are integrated with a microfluidic device to penetrate the cell membrane or coupled with external techniques to achieve DNA transfection. This work demonstrates a simple yet versatile approach to fabricate a variety of hollow nanowires for broad biomedical device applications.

“…Several techniques are applied to prepare SiNWs: lithographic methods, laser ablation, various CVD techniques, solution phase synthesis, chemical etching, molecular beam epitaxy, oxide assisted growth method [1][2][3][4][5][6]. Many of them incorporate VLS/VSS (Vapor-Liquid-Solid, Vapor-Solid-Solid) approaches in which nanoscale metal particles serve as initialization/growth agents.…”

“…Therefore, substitution of Au with other metals (Fe, Ni, Ag, Ti, Pt, Cu, In, Zn, Al, Co, Ga, Sn) [2], as well as sulfur [10], was also attempted. Nevertheless, those elements may also have detrimental effects on technology due to side reactions, atom migration, contamination, parasitic reflection etc., and their removal anticipates using other technological processes e.g.…”
