“…Usage in dental amaglams and various dental treatment and hygiene products could also represent a future direction [70]. Use of silver nanoparticles in textiles and regenerative-intend films (wound healing, burn treatment) may open new doors for the development of the field [71,72]. Osteo-synthesis products are also to be benefit from the antimicrobial effect of silver nanoparticles [73,74].…”

Nanomaterials represent a promising novel class of materials to be used as antibacterial solutions. Inhomogeneity of synthesis and characterization methods, as well as resulting variate physical and chemical properties make selection of proper nanostructure difficult when designing antimicrobial experiments. Present study focuses on the already existing evidence regarding silver nanoparticles and their antibacterial applications, with focus on various modulatory factors of reported antimicrobial efficiency. Present paper focuses on synthesis and characterization methods, factors modulating antibacterial efficiency, laboratory quantification procedures, as well as up–to-date knowledge on mechanisms of antibacterial action for silver nanoparticles. Moreover, challenges and future prospects for antimicrobial applications of silver nanoparticles are reviewed and discussed.

“…Several research has pointed that seaweeds are rich in bioactive compounds and can be a good source of carbohydrates, proteins, metabolites, and many more [56]. They have also been considered one of the important sources for the green synthesis of NPs [57] due to their ease of collection, low cost for scaling up, and very quick growth rate [69]. Algae are simple organisms, but they are among the most abundant and widespread photosynthesis-carrying life forms on Earth [59,69].…”

Algae are simple organisms, but they are among the most abundant and widespread photosynthesis-carrying life forms on Earth [59,69]. As they can reduce metal salts into metal ions to form metal NPs, algae are seen as a better option for the environmentally friendly synthesis of NPs [60].…”

“…Furthermore, if the size of the NPs is small, it will have a larger surface area. Thus, it will exhibit better antimicrobial ability against drug-resistant microbes and may penetrate cells easily [69]. NPs of smaller dimensions will eventually clump together and contact other nucleons to produce a thermostable structure [68].…”

Nanoparticles are becoming integral components in every sector considering their unmatched properties with their counter bulk material. However, in the last couple of decades, several reports suggested metal nanoparticles are toxic to biological systems either directly or indirectly. Zinc oxide nanoparticles (ZnO NPs) possess excellent optical, electrical, food packaging properties, etc. Although, the use of chemically toxic reducing agents for the synthesis of ZnO NPs induces toxicity. Therefore, biogenic synthesis of ZnO NPs has been exploited using different sources such as plant leaves, stems, fungi algae, etc NPs synthesised via these methods are biodegradable, biocompatible, low toxic, and highly effective in different applications. Algae being widely available and easy to harvest becomes a suitable candidate for ZnO NPs synthesis. Algae mediated/phycosynthesis is a technique where algae accumulate zinc oxides and reduce them to zinc ions to form ZnO NPs. The ease of synthesis of ZnO NPs using this method produces NPs in abundant quantity and of variable sizes. Intracellular and extracellular syntheses are two mechanisms of phycosynthesis of ZnO NPs. These ZnO NPs have several beneficial properties like antimicrobial, anti-cancerous, antioxidant, larvicidal, antidiabetic, etc. Additionally, it has low scale-up cost, and low energy input. This article provides detailed information about the routes of phycosynthesis of ZnO NPs using different algal strains, properties, and their potential application in the biomedical field and environmental remediation.

“…This outstanding functionality has urged us to select LLDPE as the matrix of the nanocomposites in this study. The discoveries in nanotechnology have opened the door for the effective improvisation of antimicrobial material [13][14][15][16][17][18][19][20][21]. Nanocomposite polymers are now the potential candidate in the development of safe and reliable biomaterial as they provide strong antibacterial effects and improve the thermal stability of the material [22,23].…”

A series of linear low-density polyethylene (LLDPE) polymer nanocomposites with g-C3N4-ZnO/TiO2 ternary photocatalyst (TP) at 1 wt%, 5 wt%,7 wt%, and 10 wt% was synthesised by melt blending method. The structural properties, chemical properties, photocatalytic and antibacterial activities were evaluated in this study. The addition of TP reduces the degree of crystallisation of the LLDPE nanocomposite. The OH functional group on TP increases the polarity, thus improving the LB broth’s wettability for bacterial adhesion, which enhances the inactivation effect. A minimum of 0.3 mg l−1 of Zn2+ together with ·OH and · O 2 − are required to inactivate the MDR pathogens. More than 99% inactivation in 6 h can be achieved against MDR pathogens for 5 wt% TP loading while 12 h for 1 wt% TP loading in LLDPE nanocomposites. The photocatalytic performance of the zinc oxide and titanium oxide for the degradation of methylene blue has exhibited good photocatalytic properties. The obtained results have confirmed the photocatalytic activity for the bactericidal effect of TP/LLDPE composites was dominant by ·OH and · O 2 − while slightly by holes. The purpose of this work is to obtain the optimum amount of ternary photocatalyst incorporated with LLDPE and incubation time required to kill a broad spectrum of multidrug-resistant (MDR) pathogens like E. coli, S. aureus, B. subtilis, S. flexneri, B. cereus, and K. pneumoniae. The LLDPE nanocomposite with 1 wt% showed >99% inactivation against the MDR pathogens within 12 h while with 5 wt%, it takes 6 h. The synergic action of structural properties such as crystallinity, wettability, chemical structure on the reactive oxygen species (ROS), and Zn ion release for inactivation against the MDR pathogens is deliberated.
