“…Furthermore, wavelength and energy of laser, duration of pulse, types of solvent are optimized to produce desired nanoparticles. Copper nanoparticles is also fabricated through pulse laser ablation or deposition method [18][19][20][21][22][23][24][25][26][27][28] . Forinstance, Raffi et al, fabricated zero valent copper nano-particles of 12nm size by pulse ablation method in presence of argon 18 .…”

Over the last few decades, several studies have been undertaken to determine the benefits and drawbacks of various copper nanoparticle synthesis processes. Copper nanoparticles have garnered considerable attention because of their remarkable optical and electrical properties. CuNPs' optical, electrical and chemical characteristics are substantially depending on their synthesis procedures. Copper is less expensive than precious metals such as gold and silver, and it also possesses strong photocatalytic and antimicrobial competencies.In this review, synthesis of copper nanoparticles by various methods such as physical, chemical and biological is elaborately illustrated and in the meantime it's also explained how different reaction variables like temperature, pressure, reaction time, and reactor properties affect the size, shape, and surface area of produced copper nanoparticles. Moreover, photocatalysis and antibacterial mechanism for copper nanoparticles are also illustrated with proper illustration.

“…In addition, amendments in the design of hybrid SERS substrate by integrating plasmonic NSs for the fabrication of nanophotonic devices have also been illustrated. In addition, a review by Schlucker and Fan explored the concepts and magnitudes of different assemblies of plasmonics in chemical applications. , According to the advancements of plasmonics, SERS has triggered intense attention because of its investigations and applications in different fields such as biology, chemistry, medicine, and environmental protection owing to its intrinsic features like high sensitivity and single molecular sensing capability. − The schematic representation of the Raman scattering phenomena on a metal decorated Si-based surface is shown in Figure . The Si-based surfaces (i.e., Si and its NSs) are very commonly used as a base/template for the fabrication of operative SERS-active substrates, which is due to its extensive connection and relevance in the electronics and optoelectronics industry.…”

This review presents a comprehensive synopsis of the recent developments and achievements in the research of nanosensors composed of plasmonic nanoparticles (NPs) and silicon nanostructures (NSs) for effective trace-level molecular detection. This review focuses intensively on the methodologies for the preparation and enforcement of a variety of SiNSs including (a) metal nanoparticles decorated silicon nanowires (NWs), (b) metal nanodendrites (NDs) on Si substrate, (c) plasmonic NPs decorated nanocrystalline porous silicon (pSi), and (d) silicon composed hybrid nanostructures with favorable parameters of importance in sensing. Furthermore, their potency in wide molecular sensing applications, especially chemical, biological, and explosive molecules based on surface enhanced Raman scattering (SERS) phenomenon is discussed in detail. Various demonstrations and categorizations are provided on the topic of Si-based NSs for a clear understanding to diverse readers. A roadmap is also provided at the end for achieving superior sensing materials or devices in the future.

Nano-Arsenic are synthesized using Bergenia cilliata roots extracts in water from Arsenic trioxide. The synthesized As nanoparticles, with an average diameter of 13(1) nm, self-assemble into nanotubles with average Feret diameter 530(20) nm. These As nanotubules/nanoparticles have direct band-gap of 2.74 eV and incorporates multiple defect related states. The presence of weak ferromagnetism in these nanotubules/nanoparticles are attributed to the dipolar inertactions amongst the charges on the defect sites. Owing to van der Waals interactions between nanotubules and smaller nanoparticles, nanotubules presents surface roughness which is utilized as surface enhanced raman spectroscopy substrate for probing methylene blue dye with an enhancement factor > 10 3 .
