    A review on phytotoxicity and defense mechanism of silver nanoparticles (AgNPs) on plants
    (Springer Science and Business Media B.V., 2023-03-16T00:00:00) Kumar, Sumit; Masurkar, Prahlad; Sravani, Bana; Bag, Dipanjali; Sharma, Kamal Ravi; Singh, Prashant; Korra, Tulasi; Meena, Mukesh; Swapnil, Prashant; Rajput, Vishnu D.; Minkina, Tatiana
    Silver nanoparticles (AgNPs) are noteworthy used nanomaterials in a wide array of fields, particularly in the agricultural sector. Plants play a multifarious role in the ecosystem and provide a source of food for mankind. The responsibility of the scientific community is to recognize the deleterious impact of AgNPs (1�100�nm in size) on critical crop growth and development of plants, which is required for the assessment of environmental threats to plant, human, and animal health. The continued use of AgNPs in agriculture areas may have negative effects on plant biochemical and physiological responses. The current context focused mainly on AgNPs uptake, transport, and accumulation on crop plants and summarizes different levels of phytotoxicity of AgNPs on plant functions and focused on mechanisms of phytotoxicity employed by AgNPs. Moreover, some tolerance mechanisms and various survival strategies developed by plants under AgNPs toxicity are discussed. This background provides comprehensive information necessary to facilitate profound understanding of the toxic impacts of AgNPs on crop plants. � 2023, The Author(s), under exclusive licence to Springer Nature B.V.

    Synthesis of thiolated chlorogenic acid-capped silver nanoparticles for the effective dual action towards antimicrobial and anticancer therapy
    (Springer Science and Business Media Deutschland GmbH, 2022-07-22T00:00:00) Nayak, Jyotsnamayee; Prajapati, Kumari Sunita; Kumar, Shashank; Sahoo, Suban K.; Kumar, Rajender
    Chlorogenic acid (CGA) was thiolated using Traut�s reagent. Then, thiolated chlorogenic acid (CAT) functionalized on the silver nanoparticles (AgNPs). The resulting CAT-functionalized silver nanoparticles (CAT-AgNPs) have higher stability with a uniform spherical shape compared to naked AgNPs. The average particle size is 10�nm, as revealed by transmission electron microscopy (TEM). The antimicrobial activity was higher against both gram-positive and gram-negative bacteria of spherically stable nanoparticles evaluated by the disk diffusion method. Minimal inhibitory concentration (MIC) values for CAT-AgNPs were 130��g/ml for Staphylococcus aureus and 150��g/ml for Escherichia coli. Cytotoxicity studies showed that the CAT-AgNPs show maximum activity against MCF-07 cell lines with an IC50 value of 20�ng/ml. Compared to traditional noncovalent interactions, the Ag�S covalent linkage of CAT with AgNPs helped in highly stable capping. The prepared CAT-AgNPs show anticancer and antibacterial activities, thus providing an efficient antimicrobial nano-drug carrier. Nanoparticles with a dual-mode of action help in preventing fouling of nanocarriers while delivering drugs to targeted cells, opening up many applications in nanobiotechnology and nanomedicine. � 2022, The Author(s), under exclusive licence to Springer-Verlag GmbH Germany, part of Springer Nature.
