Item Evolution of Nano-Biofertilizer as a Green Technology for Agriculture(Multidisciplinary Digital Publishing Institute (MDPI), 2023-09-24T00:00:00) Patel, Chitranshi; Singh, Jyoti; Karunakaran, Anagha; Ramakrishna, WusirikaAgriculture has long been the cornerstone of human civilization, providing sustenance and livelihoods for millennia. However, as the global population continues to burgeon, agriculture faces mounting challenges. Soil degradation, nutrient depletion, environmental pollution, and the need for sustainable farming practices are among the pressing issues that require innovative solutions. In this context, nano-biofertilizers have emerged as a groundbreaking technological advancement with the potential to reshape modern agriculture. nano-biofertilizers are innovative agricultural products that leverage the combined principles of nanotechnology and biotechnology to enhance nutrient uptake by plants, improve soil health, and promote sustainable farming practices. These specialized fertilizers consist of nanoscale materials and beneficial microorganisms. These fertilizers are eco-friendly and cost-effective and have shown promising results in various crop plants. In this review, we discuss the recent advances in the development of eco-friendly nano-biofertilizers along with an overview of the various types of nano-biofertilizers, their formulation, synthesis, and mode of application for next-generation agriculture. The importance of the interaction between nanoparticles and bacterial species and its impact on the effectiveness of nano-biofertilizers has also been discussed along with the potential benefits, challenges, and future perspectives of using eco-friendly nano-biofertilizers for sustainable agriculture, ensuring a greener and healthier future for generations to come. � 2023 by the authors.Item Probing interaction of atherogenic lysophosphatidylcholine with functionalized graphene nanosheets: theoretical modelling and experimental validation(Springer Science and Business Media Deutschland GmbH, 2023-09-09T00:00:00) Panigrahi, Abhishek R.; Yadav, Pooja; Beura, Samir K.; Singh, Jyoti; Dastider, Saptarshi G.; Singh, Sunil K.; Mondal, KrishnakantaContext: The potential of graphene derivatives for theranostic applications depends on their compatibility with cellular and biomolecular components. Lysophosphatidylcholine (LPC), a lipid component present in oxidized low-density lipoproteins, microvesicles and free circulation in blood, plays a critical role in the pathophysiology of various diseases. Using�density functional theory-based methods, we systematically investigated the interaction of atherogenic LPC molecule with different derivatives of graphene, including pristine graphene, graphene with defect, N-doped graphene, amine-functionalized graphene, various graphene oxides and hydroxylated graphene oxides. We observed that the adsorption of LPC on graphene derivatives is highly selective based on the orientation of the functional groups of LPC interacting with the surface of the derivatives. Hydroxylated graphene oxide exhibited the strongest interaction with LPC with adsorption energy of ? 2.1 eV due to the interaction between the hydroxyl group on graphene and the phosphate group of LPC. The presence of aqueous medium further enhanced this interaction indicating favourable adsorption of LPC and graphene oxide in biological systems. Such strong interaction leads to substantial change in the electronic structure of the LPC molecule, which results in the activation of this molecule. In contrast, amine-modified graphene showed the least interaction. These theoretical results are in line with our experimental fluorescence spectroscopic data of LPC/1-anilino-8-napthalene sulfonic acid complex. Our present comprehensive investigation employing both theoretical and experimental methods provides a deeper understanding of graphene-lipid interaction, which holds paramount importance in the design and fabrication of graphene-based nanomaterials for biomedical applications. Methods: In this study, we employed the density functional theory-based methods to investigate the electronic and structural properties of graphene derivatives and LPC molecule using the Quantum Espresso package. The exchange�correlation functional was described within generalized gradient approximation (GGA) as parameterized by Perdew, Burke and Ernzerhof (PBE). The valence electrons were represented using plane wave basis sets. `The Grimme�s dispersion method was used to include the van der Waals dispersion correction. � 2023, The Author(s), under exclusive licence to Springer-Verlag GmbH Germany, part of Springer Nature.
