The current study attempts to review the literature concerning the synthesis, properties, and application of carbon nanotubes (CNTs). The methods used to produce carbon nanotubes include laser ablation, electric arc discharge, chemical vapor deposition, plasma-enhanced chemical vapor deposition, pulsed laser deposition, use of low-frequency ultrasound waves, heating a bulk polymer, and bulk sputtering. CNTs have excellent mechanical and thermal properties that strongly depend upon their structure. Functionalized magnetic CNTs are involved in magnetic force microscopy used in biomedicine. The liquid and plastic limit of kaolinite can be increased by adding CNTs to it. In the medical field, CNTs have numerous applications including gene delivery to cells, cancer therapy, drug delivery, and tissue regeneration. Their antioxidant nature also enables them to be used in cosmetic products and in the field of dermatology. They are also used to purify the environment, water, and in modern food-packaging technology. The sensors containing CNTs composite pellets are sensitive to gases, such as NH3, CO2, and CO H2O. CNTs are used to construct gas containers for hydrogen storage. They are also considered ideal for structural applications and their properties can be improved by making their composites with metals. Such metals may be introduced into the core of CNTs by different methods including solid-state reaction, arc-discharge method, and electrochemical techniques. The value of absorbed hydrogen gas in CNTs varies between 0.4 and 67 mass %. Recent advances encourage more research on CNTs to increase their clinical applications in the future.

“…In metal nanoparticles (NPs), the conduction band and valence band are closely situated, allowing electrons to move freely. These free electrons contribute to the emergence of a surface plasmon resonance (SPR) absorption band 45 , 46 . For instance, silver (Ag) NPs exhibit high efficiency in absorbing and scattering light.…”

The study aims to explore a novel approach for fabricating plasmonic nanostructures to enhance the optical properties and performance of various optoelectronic devices. The research begins by employing a piezo-inkjet printing technique to deposit drops containing Ag nanoparticles (NPs) onto a glass substrate at a predefined equidistance, with the goal of obtaining arrays of Ag microdots (Ag-µdots) on the glass substrate. This process is followed by a thermal annealing treatment. The printing parameters are first optimized to achieve uniform deposition of different sizes of Ag-µdots arrays by controlling the number of Ag ink drops. Subsequently, the printed arrays undergo thermal annealing at various temperatures in air for 60 min, enabling precise and uniform control over nanoparticle formation. The printed Ag nanoparticles are characterized using field emission scanning electron microscopy and atomic force microscopy to analyze their morphological features, ensuring their suitability for plasmonic applications. UV–Vis spectrophotometry is employed to investigate the enhanced surface-plasmonic-resonance properties of the printed AgNPs. Measurements confirm that the equidistant arrays of AgNPs obtained from annealing Ag microdots exhibit enhanced light-matter interaction, leading to a surface plasmon resonance response dependent on the Ag NPs’ specific surface area. These enhanced surface plasmonic resonances open avenues for developing cutting-edge optoelectronic devices that leverage the benefits of plasmonic nanostructures, thereby enabling new opportunities for future technological developments across various fields.

“…In medicine, nanometallic elements and their oxides are extensively utilized for their antibacterial and antiviral properties-for example, nano silver, nano copper oxide, and nano zinc oxide (Ma and Hou, 2022;Yang et al, 2022;Xiang and Zheng, 2009;Cai et al, 2020). Nanosilver (Ag NPs), in particular, garners attention due to its lower minimum inhibitory concentration compared to conventional antibiotics (Maomao et al, 2023) and its eco-friendly synthesis while being capable of interfacing with various metals to combat bacteria (Peng, 2020;Rather et al, 2021;Mueez et al, 2022). Considering the wide array of implanted devices, catheters, which frequently contact the external environment, are a focus of this study, particularly ureteral stent materials.…”

Objective: This study investigates the antibacterial mechanisms of medical nanosilver latex materials by conducting antibacterial experiments on nanosilver latex, observing the morphological changes in Escherichia coli after co-cultivation with nanosilver, and detecting variations in nitric oxide, malondialdehyde, protein, and DNA fragment content. The aim is to provide a theoretical foundation for the application of antibacterial materials in medical settings.Methods: To prepare the composite latex film, nanosilver was combined with natural latex. The antibacterial efficacy of nanosilver latex were assessed using co-cultivation and colony counting methods. Electron microscopy facilitated the observation of Escherichia coli post co-cultivation with nanosilver, and subsequent changes in nitric oxide, malondialdehyde, protein, and DNA fragment content were measured.Results: The composite film of nanosilver latex demonstrated antibacterial properties, which were proportional to its concentration and inversely proportional to the particle size. Exposure to nanosilver resulted in bacterial cell membranes, leading to increased levels of nitric oxide, malondialdehyde, protein, and DNA content within bacteria.Conclusion: Nanosilver particles, especially those of 10 nm, were found to be most effective in antibacterial activity. The antibacterial effects were primarily due to the disruption of bacterial cell membranes and walls, altering intra and extracellular osmotic pressure, inducing lipid peroxidation of bacterial cell membranes, triggering of oxidative stress, and damage to DNA.
