“…Similarly, Manyasree et al (2018) studied the antibacterial activity of Al 2 O 3 -NPs against different bacteria such as Staphylococcus aureus, Streptococcus mutans, E. coli, and P. vulgaris. Green synthesized Al 2 O 3 -NPs showed enhanced antibacterial activity against Gram-positive and Gramnegative bacteria (Manikandan et al, 2019).…”

Nanotechnology has become a very advanced and popular form of technology with huge potentials. Nanotechnology has been very well explored in the fields of electronics, automobiles, construction, medicine, and cosmetics, but the exploration of nanotecnology’s use in agriculture is still limited. Due to climate change, each year around 40% of crops face abiotic and biotic stress; with the global demand for food increasing, nanotechnology is seen as the best method to mitigate challenges in disease management in crops by reducing the use of chemical inputs such as herbicides, pesticides, and fungicides. The use of these toxic chemicals is potentially harmful to humans and the environment. Therefore, using NPs as fungicides/ bactericides or as nanofertilizers, due to their small size and high surface area with high reactivity, reduces the problems in plant disease management. There are several methods that have been used to synthesize NPs, such as physical and chemical methods. Specially, we need ecofriendly and nontoxic methods for the synthesis of NPs. Some biological organisms like plants, algae, yeast, bacteria, actinomycetes, and fungi have emerged as superlative candidates for the biological synthesis of NPs (also considered as green synthesis). Among these biological methods, endophytic microorganisms have been widely used to synthesize NPs with low metallic ions, which opens a new possibility on the edge of biological nanotechnology. In this review, we will have discussed the different methods of synthesis of NPs, such as top-down, bottom-up, and green synthesis (specially including endophytic microorganisms) methods, their mechanisms, different forms of NPs, such as magnesium oxide nanoparticles (MgO-NPs), copper nanoparticles (Cu-NPs), chitosan nanoparticles (CS-NPs), β-d-glucan nanoparticles (GNPs), and engineered nanoparticles (quantum dots, metalloids, nonmetals, carbon nanomaterials, dendrimers, and liposomes), and their molecular approaches in various aspects. At the molecular level, nanoparticles, such as mesoporous silica nanoparticles (MSN) and RNA-interference molecules, can also be used as molecular tools to carry genetic material during genetic engineering of plants. In plant disease management, NPs can be used as biosensors to diagnose the disease.

“…AgNPs have been found to have a concentration-dependent antioxidant activity. Experimental results show that if adjusting the size of the synthesized LF Al2O3 from Prunus × yedoensis leaf extract and optimizing its pH, higher catalytic and antibacterial activity is manifested (Manikandan et al, 2019). Another important factor influencing the formation of nanoparticles in plant extracts is the temperature (Lin et In general, the temperature increasing helps the reaction rate and the effectiveness of nanoparticle synthesis increasing.…”

“…Several NPs such as Si, SiO 2 [15,87], MgO [88], CaO [89], and Al 2 O 3 [90] have shown significant antibacterial activity. High surface area in nanoscale, low cost, and nanocomposite formation with NPs make SiO 2 an available option against MDR bacteria, especially for potential clinical nanomaterials to treat oral biofilms [91].…”

Life-threatening bacterial infections have been well-controlled by antibiotic therapies and this approach has greatly improved the health and lifespan of human beings. However, the rapid and worldwide emergence of multidrug resistant (MDR) bacteria has forced researchers to find alternative treatments for MDR infections as MDR bacteria can sometimes resist all the present day antibiotic therapies. In this respect, nanomaterials have emerged as innovative antimicrobial agents that can be a potential solution against MDR bacteria. The present review discusses the advantages of nanomaterials as potential medical means and carriers of antibacterial activity, the types of nanomaterials used for antibacterial agents, strategies to tackle toxicity of nanomaterials for clinical applications, and limitations which need extensive studies to overcome. The current progress of using different types of nanomaterials, including new emerging strategies for the single purpose of combating bacterial infections, is also discussed in detail.
