Semiconductive silicon nanowires have been used for preparing biosensors (Clark,2016). Chemical composition is manipulated to fine-tune the conductive properties. Nano wires with flexible and rigid substrates are used for making gates, resistors, diodes, and transistors (Ranzoni et al., 2017). The resultant properties in precursor materials are used in making electromechanical devices, nanoelectronics, etc. (Song, 2018). Nanowires have also been used in nanodrug delivery systems (Sharma, 2009), personal thermal management, photocatalysis, strain sensors, lithiumbatteries,photodetectors, supercapacitors, and nanogenerators (Song, 2018 and Pu et al., 2018), biological sensors, chemical sensors (Helman et al., 2008 and Tisch, 2013). A numerous substrates are formed by using nanowires treated with different solutions. Due to high surface area, the preparation of miniature devices is limited because nanoscale structures get exploited for the final product, especially textiles (Duan, 2010).
Nanostructured Biomaterials for Load-Bearing Applications
Published in Ashwani Kumar, Mangey Ram, Yogesh Kumar Singla, Advanced Materials for Biomechanical Applications, 2022
A wide range of biomedical applications of nanostructured biomaterials includes bioimaging, cancer or virus detection, gene detection and diagnosis [20]. Metallic nanoparticles such as gold nanoparticles are in high demand for bioimaging like MRI and CT scans. Quantum dots are also used for imaging in medical diagnosis. Silicon nanowires can be used to detect specific genes as well as for cancer/virus detection. Other nanomaterials with similar applications, such as disease detection and gene detection, are carbon nanotubes.

The application of multijunction photovoltaic cells, with their complex-layered structures, in terrestrial applications requires an improved understanding of thermomechanical reliability and testing metrologies as the basis for improved lifetime predictions (Kinsey and Edmondson 2009). On the other hand, the temperature of the single solar cell was investigated numerically with finite element method with treating the inefficient light energy as heat flux through the cell surface without considering the inner structure of the cell (Theristis and O’Donovan 2015; Zhou et al. 2015). Next, promising path for photovoltaic development is the usage of silicon nanowires (Hochbaum et al. 2015; Cui et al. 2001; Kelzenberg et al. 2008; Sivakov et al. 2009). Experimentally, the fabrication (Smeltzer, Kendall, and Varnell 1973) of such cells is now possible using advanced technologies such as orientation dependent etching, electron beam pattern generation, epitaxially refilled deep grooves and deep grooves diffusion. Prior theoretical investigations (Chadda and Wolf 1973; Kleinman 1961) of vertical multijunction cells have been restricted to structures with alternate (p-n) junction with exposed junction areas. We propose the method (Khalis et al. 2011) to estimate all the parameters of a solar cell just from a single J-V curve under one constant illumination level based on the LambertW function. The paper is organized as follows: Section 2 describes the model, whereas Section 3 presents the discussion of the obtained results and the conclusion is given in Section 4.

Silicon nanowire-based biosensors are highly sensitive to detecting biomolecules. Silicon nanowires-based sensor has made an incredible impact on cancer screening or blood analysation [222]. Such sensor offers the opportunity for earlier detection of oncological pathologies [223]. Considering various functions and features, highly sensitive Ag NW placement at the interface could help improve ion collection and could sense small amount of electrolyte at the interface.
