“…Various sizes of spherical nanoparticles have been also reported in other studies by TEM analysis [ 54 , 77 , 78 ]. It is well known that the biogenically synthesized AgNPs using plants or microorganisms are an effective way the advancement of secure and proficient control approach against resistant bacteria [ 79 – 82 ]. Herein the potential of synthesized T/AgNPs has been determined in anticandidal activity.…”

Till now the exact mechanism and effect of biogenic silver nanoparticles on fungus is an indefinable question. To focus on this issue, the first time we prepared hydrothermal assisted thyme coated silver nanoparticles (T/AgNPs) and their toxic effect on Candida isolates were determined. The role of thyme (Thymus Vulgaris) in the reduction of silver ions and stabilization of T/AgNPs was estimated by Fourier transforms infrared spectroscopy, structure and size of present silver nanoparticles were detected via atomic force microscopy as well as high-resolution transmission electron microscopy. The biological activity of T/AgNPs was observed against Candida isolates from COVID-19 Patients. Testing of virulence of Candida species using Multiplex PCR. T/AgNPs proved highly effective against Candida albicans, Candida kruzei, Candida glabrata and MIC values ranging from 156.25 to 1,250 μg/mL and MFC values ranging from 312.5 to 5,000 μg/mL. The structural and morphological modifications due to T/AgNPs on Candida albicans were detected by TEM. It was highly observed that when Candida albicans cells were subjected to 50 and 100 μg/mL T/AgNPs, a remarkable change in the cell wall and cell membrane was observed.

Plant diseases pose a significant threat to global agriculture, impacting crop yield and food security. Traditional methods of disease management often involve the application of chemical pesticides, which raise environmental and health concerns. In recent years, nanotechnology has emerged as a promising avenue for sustainable and effective plant disease management. This review provides an overview of the applications and mechanisms of action of silver nanoparticles (AgNPs) and zinc nanoparticles (ZnNPs) in combating plant pathogens. AgNPs and ZnNPs have garnered attention due to their antimicrobial properties, biocompatibility, and versatility. They exhibit multifaceted mechanisms of action, including membrane disruption, generation of reactive oxygen species (ROS), interference with enzymatic processes, and inhibition of microbial growth. These nanoparticles can effectively target a wide range of plant pathogens, including bacteria, fungi, and viruses. Moreover, they can be used as carriers for the controlled release of antimicrobial agents and nutrients, further enhancing their utility in agriculture. Furthermore, AgNPs and ZnNPs have demonstrated compatibility with environmentally friendly and sustainable agricultural practices. Their targeted delivery reduces chemical waste and minimizes environmental contamination. Additionally, these nanoparticles can stimulate the plant's innate defense mechanisms, enhancing its resilience against diseases. This review highlights the potential of AgNPs and ZnNPs as innovative tools for plant disease management, offering sustainable and effective alternatives to conventional pesticides. The ongoing research in this field aims to optimize nanoparticle formulations, assess their safety, and develop integrated disease management strategies to enhance agricultural sustainability and food production.

Modern nanotechnology is playing a vital role in our daily life by contributing in different domains such as usage of nanoparticles for target-specific drug delivery system, as these nanoparticle are being used as scratch proof coating on glass for tracking of biomolecules. Some emerging applications of nanoparticles include usage of nanoparticles for diagnostic purposes such as biomedical imaging and as green technology producing nano pesticides. The use of endophytic or plant beneficial bacteria for the production of metallic nanoparticles have shown promising results in not only controlling the pest but also contributing in enhanced developmental growth due to their small size, target specificity, and enhanced interaction with the plant in controlled environment. As for increasing environmental crisis, use of biological methods to remediate the environment is becoming a necessity. Green technology based nano-materials being used now a days in multiple fields, especially in bio-control of pests. This review is based on the microbial synthesized metallic nanoparticles, which are being used as nano pesticides (nanoparticles are pesticides).
