Biodirected synthesis of palladium nanoparticles using Phoenix dactylifera leaves extract and their size dependent biomedical and catalytic applications

Abstract

Graphical representation of green synthesis of PdNPs and their biological and catalytic applications.

Green synthesis palladium nanoparticles mediated by white tea (<em>Camellia sinensis</em>) extract with antioxidant, antibacterial, and antiproliferative activities toward the human leukemia (MOLT-4) cell line

“…The PdNPs have enormous catalytic potential in various organic transformations, including Suzukicross, Mizoroki-Heck, Stille, and Sonogashira coupling reactions. [9][10][11] However, the application of PdNPs in the biomedical field is yet to be adequately investigated, although the green-synthesized PdNPs possess remarkable antioxidant 12,13 and antimicrobial activities. 12,14 Plant-derived PdNPs seem to have potential for application in cancer therapy because these compounds are also toxic to cancer cells.…”

Green synthesis of zinc oxide nanoparticles and zinc oxide–silver, zinc oxide–copper nanocomposites using Bridelia ferruginea as biotemplate

Synthesis, characterization and antifungal activities of eco-friendly palladium nanoparticles

“…21 Smaller and spherical nanoparticles were observed to have more antibacterial effects compared to larger and irregular shaped nanoparticles. 21 At 10 À9 M concentration, Pd has also been reported to exhibit toxicity against Gram-positive bacteria such as Staphylococci, while at concentrations above 10 À9 M, it exhibits toxicity towards Gram-negative bacteria. 23 Two fungi, Aspergillus avus and Candida albicans have previously been tested against PdNPs as well.…”

“…However, there are a few studies that have been conducted on PdNPs for their antimicrobial capabilities. [21][22][23][24] Tahir et al demonstrated the use of biosynthesized PdNPs as antibacterial compounds against Pseudomonas aeruginosa. 21 Smaller and spherical nanoparticles were observed to have more antibacterial effects compared to larger and irregular shaped nanoparticles.…”
