Biological synthesis of gold nanoparticles using Magnolia kobus and Diopyros kaki leaf extracts

Characterisation of gold nanoparticles synthesised by leaf and seed extract ofSyzygium cuminiL.

“…The potential of plant extracts to reduce various metal ions into corresponding nanoparticles forms has been well documented [3,[22][23][24][25][26]. Towards this effort, we have recently explored the potential of S. cumini for the synthesis of SNP.…”

“…Similar correlation between size of nanoparticles and polyphenolic contents has been documented through previous studies. The reduction in active species like polyphenolic content in the reaction mixture, reduces the synthesis rate and nucleation process [4,22,37]. As the biochemical constituents vary from plant to plant and even within different tissues of a plant in concentration and type, different types of plant extracts directed nanoparticles with different sizes and shapes.…”

“…GNP have applications in therapeutic [5], catalysis [2], immunoassay and immunosensing [6], diagnostic and drug delivery [7][8][9][10], analyte sensing [11][12][13], cancer cell diagnostics and selective photothermal therapy [14,15], photoacoustic imaging [16,17] and cancer treatment [18]. Various plant extracts have been explored for the synthesis of GNP, namely tamarind [19], Aloe vera [20], Pelargonium graveolens [21], Diopyros kaki [22], Eucalyptus camaldulensis and Pelargonium roseum [23], coriander [24], Scutellaria barbata [25], lemongrass [26], Datura metel, Carica papaya and Solanum melongena [27]. Additionally, live plants like Brassica juncea [28], Avena sativa [29], Medicago sativa [30] and Chilopsis linearis [31] have also been used for GNP synthesis.…”

“…Different plants have differential potential for metallic nanoparticle synthesis in terms of size and shape [3,22,27]. We have recently reported on the Syzygium cumini leaf extract (LE) and seed extract (SE) mediated biosynthesis of silver nanoparticles (SNP) and their characterisation [4].…”

TTC- Based Test as an Efficient Method to Determine Antibiofilm Activity of Silver Nanoparticles

“…The synthesis of silver nanoparticles used microbiological method is the important part of nanobiotechnology, connecting the range of biotechnology research with nanotechnology. However, despite some reports, still many aspects of nanoparticles biosynthesis should be studied in detail It was observed that biosurfactants produced by microorganisms play very important role in aggregation and stabilization process [3][4][5][6][7][8][9][10][11][12][13]. They adsorbed onto Ag-NPs surface stabilizing the nanoparticles and prevent their aggregation.…”
