Drymoglossum piloselloides is one of the epiphytic plants that is commonly found in Southeast Asia region. In this study, the ethanol extract of D. piloselloides plant has been used in the green synthesis of silver nanoparticles. The synthesized silver nanoparticles were characterized by ultraviolet-visible (UV-Vis) spectrophotometry, X-ray diffraction (XRD),Fourier-transform infrared (FTIR) spectroscopy, and transmission electron microscopy (TEM) measurements. The UV-Vis spectrum of silver nanoparticles showed a maximum wavelength at 453 nm. The XRD measurement showed the silver nanoparticles peaks at 38.38°, 44.60°, 64.76°, and 77.62°. The FTIR spectra provided evidence of the interaction between silver and chemicals in the plant extract as a weak signal at 682 cm-1. Meanwhile, TEM revealed an average size of 12.63nm. The synthesised silver nanoparticles were utilised for the reduction of 4-nitrophenol with a conversion percentage of up to 100% with a reduction reaction rate constant of 7.104 s-1. In addition, methylene blue was also successfully reduced with the synthesised silver nanoparticles as the catalyst with a reduction reaction rate constant (k) of 21.150 s-1. This study highlights the superior advantage of utilizing ethanolic extract of D. piloselloides to prepare silver nanoparticles with promising catalytic reduction purposes.

Silver and its compounds have been used for thousands of years as antibacterial and medicinal agents. Silver nanoparticles (AgNPs) subsequently received much attention due to their unusual physical, chemical, and biological properties, which are mainly caused by AgNP size, structure, composition, luster, and structure compared to their bulk species. When free radicals interact with bacteria, they can cause damage to the cell membrane, enabling it to penetrate and eventually lead to cell death. Compared to other salts, silver nanoparticles have excellent antibacterial activity due to their large surface area, allowing for high interaction with bacteria. There are many techniques for producing silver nanoparticles, including physical, chemical, and biological processes.Physical and chemical processes for making silver nanoparticles are expensive and complicated, whereas biological approaches are easier and safer to implement. In the biological and environmental areas, metal nanoparticles with controlled particle size and surface chemistry have a broad spectrum of applications. Nanomaterials must becharacterized in addition to the manufacturing procedures to explore differences in activity based on morphological distinctions. AgNPs are widely used as antibacterial agents in the field of health, food storage, textiles, and various environmental applications.So, in this systematic review, we examined silver nanoparticle preparation methods, characterization, applications, and fundamental concepts of silver nanoparticles (AgNPs).

The global demand for essential oils is expanding as a result of their numerous applications and increasing consumer exposure in the international market. Essential oils (EOs) are mixtures of volatile compounds including, but not limited to, phenolics, esters, ketones, terpenes, alcohols, and amides. The majority of EOs have excellent antioxidant, antibacterial, and functional activities. These natural products have conquered space in the food, drug, and cosmetic commercial arena. Unfortunately, like many lipophilic and aromatic active substances, EO presents some drawbacks such as low water solubility, strong organoleptic characteristics, low stability, and limited administration routes, which confines their Industrial use. EOs can be nanoencapsulated to increase their persistence, and bioavailability in the biological process by employing the optimum encapsulation polymers. Additionally, these particles are capable of controlling the release of the EOs promoting a prolonged preservative effect in cosmetics and foods, as well as a potential advantage for pharmaceutical dosage forms. The current research focuses on the essential features of EOs as well as their encapsulation methods. Furthermore, the potential applications of applying nanoencapsulated essential oils in the healthcare field were addressed.
