Recently, extensive research has been conducted on wound healing and drug release materials. In this perspective, a cellulose acetate (CA) and a poly(vinylidene fluoride) (PVDF) blended polymer membrane were prepared, and their drug release activities against wound healing proteins were evaluated using molecular docking studies. The CA, PVDF, and CA: PVDF polymer membranes were synthesized using the solution-casting technique with DMSO as the solvent. The optimized CA: PVDF polymer membrane was characterized using various techniques for different compositions. The FTIR analysis confirms the variation in the peak when varying the PVDF content, indicating complexation. The semicrystalline CA matrix collapsed due to this complexation, as evidenced by the reduced intensity in the CA: PVDF XRD peaks. The XRD results confirm that the sample exhibits a semicrystalline nature, and increasing the PVDF content enhances its amorphous character. The DFT / B3LYP method was employed to calculate the molecular properties of CA, PVDF, and CA: PVDF. The molecular reactivity of CA, PVDF, and CA: PVDF molecules was investigated through frontier molecular orbital (FMO) analysis and additionally, the molecular electrostatic potential (MEP) contour map and mulliken atomic charge distribution analysis were used to identify possible electrophilic and nucleophilic reactive sites. Furthermore, molecular docking studies were performed to analyze the binding affinity of CA: PVDF with wound healing proteins 1MKW, 3OSL, 1TBQ, and 1VIT. The results suggest that CA: PVDF exhibits potent wound healing properties.
Plant diseases caused by fungi, bacteria, and viruses pose a critical threat to global food security. Chemical pesticides are ineffective and might be harmful to the environment. Hence, there is an urgent need to develop alternative and eco-friendly strategies for managing plant diseases. Nanobiotechnology, particularly the use of silver nanoparticles (AgNPs), offers a promising solution. Antagonistic bacteria, due to their natural antimicrobial properties, can serve as effective agents for nanoparticle synthesis. This study investigates the green (bacteria-mediated) synthesis of AgNPs using Pseudomonas fluorescens as an eco-friendly approach to control Cochliobolus miyabeanus, the source of brown leaf in rice. The synthesis of AgNPs was facilitated by Pseudomonas fluorescens, utilizing bacterial biomolecules and enzymes to catalyze nanoparticle formation. FTIR analysis revealed the involvement of secondary metabolites, identified the functional group in the 3434–400 cm⁻1 range. The nanoparticles were further characterized using UV–Vis spectroscopy, SEM (revealing spherical, rod, and cubic shapes), and EDX (showing 32.93
Microplastics and nanoplastics are addressed as emerging pollutants hindering plant and soil health, by and large. Accumulation, toxicity, and future impact necessitate dire attention in the present century owing to global health contexts. Plastic accumulation in plants not only affects plant growth and yield but can alter soil microbial community dynamics through its chemical interactions. Hence plant, soil and planet health need to be critically studied for creating awareness regarding environmental impacts. Further, the serious consequences that can affect agricultural production and productivity are summarized for impending repercussions and reverberations in agroecotoxicology. Potential limitations that can be explicitly considered in augmenting plant growth promotion and associated degradation strategies are foreseen to have large benefits for the farming community. Ecosystem dynamics about heavy metal toxicity, nano-pollution, and soil fertility management are discussed for holistic environmental management of Plastics upon plant and soil health. Future perspectives are concerned with interdisciplinary research prospects and stringent legal practices in the agricultural realm are accounted for possible mitigating strategies. Hence, the present review focusses in holistic management of MNPs agroecotoxicology for regulatory policies, bioremediation potentials, awareness and education. Environmental sustainability and pollution management will aid in potent waste management and circular economy prospects. A critical assessment incorporating global health perspectives affected by the holistic damage impeded by plastics is corroborated for holistic environmental impact analysis. The present review compiles the environmental microbiology perspectives on the effective management of plastics and associated deleterious outcomes. The review addresses the key questions enlisted: (1) How MNPs account for everlasting impacts in the environment?. (2) What are the consequences of MNPs upon plant probiotics and associated soil community microbial dynamics?. (3) What is the future of agro-ecotoxicology of MNPs?. (4) What are the implications of MNPs in augmenting plant growth through nutrient and biogeochemical cycling?. (5) How waste management of MNPs can enrich global policies, awareness and circular economy?.
The increasing demand for energy has sparked interest in the development of sustainable cost-effective materials for electrochemical energy conversion devices such as fuel cells and solar cells. Since the performance of these devices depends greatly on their electrode and electrolytic components, enormous efforts have been devoted in the direction of fabricating these components from biopolymers and it becomes an interesting area of research. In this review, we particularly focus on the utility of biopolymer-derived electrode and electrolyte components (biopolymer components, BPCs) and their impact on the performance of two major energy conversion devices namely fuel cells and dye-sensitized solar cells (DSSCs). The functional features of biopolymers, properties, and their applications in DSSCs and fuel cells are summarized. Besides, various modification strategies adopted to upgrade their physico-chemical properties and their benefits with a primary focus on the device performance are emphasized. Ultimately, this review highlights the future possibilities of BPCs in three distinct realms: (i) design and development of exceptionally efficient components, (ii) fabrication of sustainable and economically viable energy conversion devices, and (iii) optimization of operational parameters for real-world applications. In light of this, the review will provide guidelines for the development of BPCs for the production of sustainable and economically viable energy conversion devices with the goal of delivering affordable clean energy to the society.
