“…Peaks observed at 1,638, 1,309 and 1,025 cm À1 associate with N-H bending, C-O stretch and C-N stretch, respectively. The peaks revealed binding of an amide linkage with Pb-AgNPs, which is clearly evident in the IR region of the electromagnetic spectrum, demonstrating the existence of biomolecules as a capping agent for Pb-AgNPs (Ramachandran et al 2015;Bhople et al 2016). Pb leaves contain a large number of phytochemicals such as amino acids, proteins, hydroxychavicol, eugenol, polyphenols, and several alkaloids and terpenoids, which have reduction properties (Guha 2006).…”

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 a challenging target for compounds antagonistic to virulent factors. Biologically synthesized silver nanoparticles (AgNPs) are reported as anti-QS and anti-biofilm drugs against bacterial infections. The present study reports on the synthesis and characterization of Piper betle (Pb) mediated AgNPs (Pb-AgNPs). The anti-QS activity of Pb-AgNPs against Chromobacterium violaceum and the potential effect of Pb-AgNPs on QS-regulated phenotypes in PAO1 were studied. FTIR analysis exhibited that Pb-AgNPs had been capped by phytochemical constituents of Pb. Eugenol is one of the active phenolic phytochemicals in Pb leaves, therefore molecular docking of eugenol-conjugated AgNPs on QS regulator proteins (LasR, LasI and MvfR) was performed. Eugenol-conjugated AgNPs showed considerable binding interactions with QS-associated proteins. These results provide novel insights into the development of phytochemically conjugated nanoparticles as promising anti-infective candidates.

“…Owing to the unique advantages of electrochemical techniques, electrochemical detection of inorganic pollutants such as nitrite has received significant attention in the recent era. Nitrite contamination in natural water, soil and food [1,2] and subsequently in human beings and animals results from its extensive utilization as an additive, preservative in food industries, fertilizer and as corrosion inhibitor [3][4][5][6]. Nitrite, also formed by the conversion of nitrate in the saliva pose serious problem to human health [7,8].…”

Silver nanospheres (AgNS) with SPR band ∼417 nm was synthesized by Green synthesis, using a pre‐hydrolysed liquor (PHL) of Nilgiri wood without any pretreatment. The synthesis was carried out at room temperature and was complete within three hours. The reduction and stabilization of silver is brought about by hemicelluloses present in the pre‐hydrolysed liquor. Electrochemical oxidation of nitrite on glassy carbon electrode (GCE) modified with the AgNS in 0.1 M phosphate buffer solution (PBS) of pH 7.0 was found to occur at 0.86 V with respect to Ag/AgCl. Electrochemical sensing experiments with AgNS/GCE showed a linear range of detection between 0.1 to 8 μM, with detection limit of 0.031 μM and a sensitivity of 580 μA mM−1cm−2.

“…However, the reducing reagents may increase the environmental toxicity or biological hazards . Moreover, plant‐mediated nanoparticle synthesis is preferred because it involves non‐toxic reagents, is cost‐effective, uses environmentally friendly solvents, is a single‐step method for biosynthesis process and is safe for humans and the environment.…”

Green tea extract having many phenolic hydroxyl and carbonyl functional groups in its molecular framework can be used in the modification of Fe 3 O 4 nanoparticles. Moreover, the feasibility of complexation of polyphenols with silver ions in aqueous solution can improve the surface properties and capacity of the Fe 3 O 4 @green tea extract nanoparticles (Fe 3 O 4 @GTE NPs) for sorption and reduction of silver ions. Therefore, the novel Fe 3 O 4 @GTE NPs nano-sorbent has potential ability as both reducing and stabilizing agent for immobilization of silver nanoparticles to make a novel magnetic silver nanocatalyst (Fe 3 O 4 @GTE/Ag NPs). Inductively coupled plasma analysis, transmission and scanning electron microscopies, energy-dispersive X-ray and Fourier transform infrared spectroscopies, and vibrating sample magnetometry were used to characterize the catalyst. Fe 3 O 4 @GTE/Ag NPs shows high catalytic activity as a recyclable nanocatalyst for the reduction of 4-nitrophenol at room temperature.
