Phytonanotechnology: Recent applications and the role of Biocorona

Phytonanotechnology is lately gaining increased interest owing to its potential to modernize agriculture for better yield and nutritional quality. Consequently, Nano-Agri products like nano-biosensors, nano-carriers, and growth augmenters are being developed and applied. However, the limited knowledge of molecular interactions taking place at nano-bio interface remains a major concern. The nanotechnological interventions for healthier crops could rather turn out tobe risky and inefficient in the absence ofclear understanding of molecular mechanisms of nano-bio interactions. Upon entry into tissues or cells, nanoparticles (NPs) adsorb biomolecules forming a biocorona which determines NP uptake, translocation, and reactivity. The composition of biocorona is dependent on the physicochemical characteristics of the NPs, their surroundings, and the interaction time. Recent nascent studies in plants showed the potential of biocorona to influence major cellular pathways or plant responses like energy synthesis, pathogenesis, stress tolerance, and leaf senescence. This mini-review aims at summarizing the recent application of phytonanotechnology, the current status of biocorona studies with an overview of research bottlenecks and future prospects.

Green Reactants Act As Natural Precursor For Facile Synthesis Of Nanoparticles Using Withania Somnifera

Nanotechnology includes physical and chemical approaches intended for their phytofabrication of metal nanoparticles. Most of the time, these methods are not as safe as these are associated with the utilization of extremely noxious and hazardous substances that produce biological problems. Due to their manifold applications, various biological methods are gaining admiration for the fabrication of silver nanoparticles (AgNPs). The utilization of vegetative parts in the biosynthesis of nanoparticles (NPs) emerges as a commercial and ecological approach. The spectroscopic profile confirms the occurrence of a functional peak at 360 nm. Fourier transform infrared spectroscopy (FTIR) studies indicate that phenol groups are responsible for phytofabrication of NPs. The results of microbicidal screening confirm that broad spectrum of inhibition was found to be observed in 400 μL of biosynthesized AgNP against E. coli (23 mm) and B. cereus (22.3 mm) Therefore, the progress of simple photosynthesis methods avoid deleterious and harmful properties has fascinated major attention in this field.
