“…Amphotericin is also reported the maximum inhibition about 13.2 ± 0.01 against the above mentioned species with slight difference of kanamycin. Comparatively both antibiotic shows poor inhibitory action against S. aureus [11, 16]. Seed extract represents that maximum inhibition against S. aureus, E. coli and K. pneumonia , minimum inhibition against P. vulgaris and A. niger Sp .…”

“…The mixture was then filtered by filter medium and dried at 80°C in the hot air oven for 24 h. Thus, the mixture is called as ultrasonic assisted activated carbon (UA-AC). Those two forms of activated carbon was used and characterised for experimental purpose [16].…”

“…Thus, the sustainability of raw tea waste (RTW) at extreme pH condition scavenges metal ions which lead to less contact time with high potential. The two step surface modification of activated carbon is done and characterised by scanning electron microscopy (HRSEM) to understand the structural changes due to interaction between the molecules, energy dispersive X‐ray (EDX) analysis [16]. Cellulose, lignin, tannin, and structural proteins are the constituents of RTW which makes it regenerated.…”

The bio-nanocomposite role in wastewater treatment is a primary concern of this research. The physical, chemical, mechanical stability and antimicrobial activity of these bio-nanocomposites were investigated. The method is based on the biological reduction of aqueous copper sulphate pentahydrate, lead nitrate, silver nitrate, zinc sulphate heptahydrate salt using seed extract of Eucalyptus globulus as reducing agent at ambient temperature. The synthesised metal nanoparticles (MNPs) were analysed by UV-visible spectroscopy and Fourier transform infrared spectroscopy analyses. An ex-situ method involves constructing bio-nanocomposite by blending MNPs with tea waste activated carbon. Cross-linking in activated carbon takes place which was confirmed by changes in the mixture of components. The present yield of activated carbon was characterised by scanning electron microscopy and energy dispersive X-ray measurements. A few micro or nano range, spherical shape of activated carbon was studied by SEM. The main elements found in the activated carbon by EDX are C, O, S, Ag, Cl and Cu. The efficacy of such active bio-nanocomposite (ABN) tested against human pathogen includes both type of bacteria and fungus. The inhibitory effects of ABN are discernible from the results that reveal biologically inseminated MNPs can be used to clean up the contaminated environment.

“…However, the peak was disappeared in AgB spectra and shifted to 1605 cm -1 in AgCN spectra, suggesting the binding of C=O functional group with Ag nanoparticles [28]. The peak at 1083 cm -1 which attributes to the ether linkage (C-O or C-O-C) stretching vibrations was observed in AgCN, revealed that the phenolic compounds in C.N leaves extract have been successfully absorbed on the surface of Ag nanoparticles [29,30]. A new peak appeared at 483 cm -1 in AgCN and AgB spectra confirming the formation of Ag nanoparticles, while the small peak at 1318 cm −1 is refer to the (C-OH) group [31].…”

Advanced extraction method such as simultaneous ultrasonic-hydrodistillation (UAE-HD) extraction method has been proved to increased extraction yield of plant material yet the application of this method in the preparation of metal nanoparticles has not been studied. In this study, Cymbopogon nardus (C.N) extracted via UAE-HD extraction method was used to synthesis silver (Ag) nanoparticles. XRD and TEM analysis confirms the formation of spherical shape Ag nanoparticles with size ranging between 10-50 nm. FTIR spectra suggest the presence of bioactive compounds in the C.N leaves extract that may responsible to the stabilization and reduction of Ag ions (Ag + ) to metallic Ag nanoparticles (Ag 0 ). The TPC analysis successfully proved that huge number of phenolic compound greatly involved in the nanoparticles synthesis process. Next, the catalytic activity of the synthesized Ag nanoparticles was tested towards the degradation of 2,4-Dicholorophenoxyacetic acid herbicide with remarkable degradation performance up to 98%. Kinetic study confirms that surface reaction was the controlling step of the catalytic process.

Nature and nanotechnology have not yet achieved a lucid correlation in the field of science but together they have exhibited immense potential towards the advancement and modification in future science and technology. Due to the unique properties of nanomaterials like nanoparticles gained considerable importance. Among all the nanoparticles, zinc oxide (ZnO NPs) are greatly utilized in sensors, catalysis, bioscience, etc. Antimicrobial activity by ZnO NPs had more attention by the implementation of nanotechnology for the preparation of ZnO NPs. At present, antimicrobial activity of ZnO NPs using Aegle marmelos (A. marmelos) leaves extract was done. The ZnO NPs subjected to UV-Vis, FT-IR, XRD, SEM and TEM analysis. The presence of phenolic group in extract has the capacity to form ZnO NPs and act as stabilizing agent. Every 5 min interval ZnO NPs was formed which recorded by UV-Vis spectrophotometer. The SEM analysis displayed a fine spherical ZnO NPs and EDAX report showed that the existence of zinc and oxygen in the ratio of 30.51% and 69.49%. The antimicrobial activity of ZnO NPs has high percentage inhibition against A. niger at 1000 ppm. Till now, no research carryout on A. marmelos mediated ZnO NPs and applications towards antimicrobial activity.
