Synthesis of silver nanoparticles (SNPs) by fungi is emerging as an important branch nanotechnology due to its ecofriendly, safe, and cost‐effective nature. In order increase the yield biosynthesized SNPs desired shape size, it necessary control cultural physical parameters during synthesis. We report optimum synthesis on malt extract glucose yeast peptone (MGYP) medium at pH 9–11, 40–60°C, 190.7 Lux in sun light. The salt concentrations, volume filtrate biomass quantity were found be...

Quorum sensing (QS), the communication signaling network, regulates biofilm formation and several virulence factors in Pseudomonas aeruginosa PAO1, a nosocomial opportunistic pathogen. QS is considered to be challenging target for compounds antagonistic virulent factors. Biologically synthesized silver nanoparticles (AgNPs) are reported as anti-QS anti-biofilm drugs against bacterial infections. The present study reports on synthesis characterization of Piper betle (Pb) mediated AgNPs...

Abstract In spite of the limited sources fossil fuels, energy demand has been considerably increased since last century. The problems associated with global warming due to rising atmospheric greenhouse gas levels and scarcity fuels make it imperative reduce our heavy dependency on fuels. These reasons forced countries throughout world search for new fuel alternatives. Biofuel have gathered considerable attention their inherent benefits, like lower emission, renewability, sustainability....

Curcumin is one of the polyphenols, which has been known for its medicinal use since long time. shows poor solubility and low absorption, therefore, as nanoparticles beneficial due to their greater absorption. The main aim present study was formation curcumin (Nano curcu), evaluation antibacterial activity against human pathogenic bacteria formulation Nano curcu-based cream. We synthesized curcu by sonication method. synthesis assessed in water UV–visible spectrophotometry. Further, were...

Apart from being fast, studies related to have geared their efforts towards development nanomaterial-based sensors that are affordable, robust reproducible. The equipped immobilized bioreceptor...

Aim: The authors report the biological synthesis of zinc oxide nanoparticles (ZnO-NPs) from petals extract Rosa indica L. (rose). Its efficacy was evaluated against two dermatophytes: namely: Trichophyton mentagrophytes and Microsporum canis which cause onychomycosis. activity antibiotics tested dermatophytes enhanced, when in combination with ZnO-NPs. Methods results: synthesised ZnO-NPs were preliminary detected by using ultraviolet UV visible spectroscopy, showed specific absorbance....

Lawsonia inermis mediated synthesis of silver nanoparticles (Ag-NPs) and its efficacy against Candida albicans, Microsporum canis, Propioniabacterium acne Trichophyton mentagrophytes is reported. A two-step mechanism has been proposed for bioreduction formation an intermediate complex leading to the capped was developed. In addition, antimicrobial gel M. canis T. also formulated. Ag-NPs were synthesized by challenging leaft extract L. with 1 mM AgNO3. The characterized Ultraviolet-Visible...

Lingzhi or Reishi medicinal mushroom, Ganoderma lucidum, has been used over the ages as highly herb in Orient. Many useful properties of this fungus are still being studied; we report here a new facet "elixir life" mycosource for synthesis metal nanoparticles. Treating extracellular suspension filtrate mycelia G. lucidum with silver nitrate reduces ions to Optical detection followed by confirmation through spectroscopic analysis suggests that can be purpose safe and sure nanoparticles,...
