Biogenic metallic nanoparticles (BMNPs) are nanostructure materials synthesized through biological processes that have gained significant attention due to their small size and high surface area-to-volume ratio. BMNPs several advantages over chemically ones eco-friendly synthesis regimen, sustainability, biocompatibility, diverse multifarious biomedical applications. Moreover, the superior cytocompatibility stability capping layer (MNPs), reduces like hood of toxicity side effects, making...
Abstract Surface properties always play a dominant role in the energy storage devices. Understanding surface phenomena is key to tune device using biowaste based porous nano carbons. Here, Callerya atropurpurea pod derived peculiar nanocarbons are synthesized by pyrolysis at different temperatures without any synthetic templates approach. Elaborate analysis of textures on effect pore size, volume and specific area capacitance frequency response behavior were studied detail. Electrochemical...
Introduction: The use of environmentally benign resources for nanoparticles synthesis is consistently pushed to the front burner in a bid ensure and enhance environmental protection beneficiation. In this light, application different plant parts reduction stabilization gaining popularity. Materials Methods: contribution, we have exploited Securidaca inappendiculata stem extract (SISE), as reducing stabilizing agent room temperature highly stable dispersed AgNPs. major bioactive compounds...
Herein, the synthesis of a biocompatible silver nanoparticles (AgNPs), for colorimetric detection toxic mercury (II) ion (Hg2+), is reported. Phenolic-rich fraction Asystasia gangetica leaf was extracted and used as reductant salt, all within hydrophilic konjac glucomannan (KgM) solution stabilizer, at room temperature (RT). The bioactive components phenolic extract (AGPE), elucidated with (UHPLC-MS-QTOF-MS), revealed plethora compounds, which can facilitate reduction salt ambient...
Abstract Herein, a sensitive colorimetric detection strategy is proposed for Ag + based on the use of environmentally friendly synthesis gold nanoparticles (AuNPs), at room temperature, using (tannic acid, TA), as reductant and pullulan (PUL) stabilizing agent. The colloidal solution (TA/PUL-AuNPs), optimal conditions, showed maximum absorbance 529 nm with berry red color. TEM FESEM validated that particles are spherical monodispersed, while other characterization results elucidated role in...
In this article, we have reported an environmentally benign and cost-effective method for the synthesis of monodispersed silver nanoparticles (AgNPs), based on Centella asiatica phenolic extracts (CAPE). The presence phenolics was confirmed by ultra high-performance liquid chromatography coupled with electrospray ionization quadrupole time flight mass spectrometry (UHPLC-ESI-qTOF-MS). Colloidal AgNPs synthesized under different concentrations nitrate were monitored a UV-vis...
This study investigated the antioxidant, antimicrobial, anticancer, and phytochemical profiling of extracts from leaves stem/root Acanthus ebracteatus (AE). The total phenolic content (TPC), flavonoid (TFC), 2,2-diphenyl-1-picryl-hydrazyl-hydrate (DPPH) radical-scavenging activity, 2, 2'-azino-Bis-3-ethylbenzothiazoline-6-sulfonic acid (ABTS) metal chelating activities (MCA), ferric reducing antioxidant power (FRAP) oxygen radical capacity (ORAC) were used for assessment. ethanolic (AEL-nor)...
There has been growing interest in the biological and pharmacological potential of C. odorata recent times. While a number reports had highlighted beneficial attributes various extracts prepared from odorata, properties lipophilic extract remained unexplored. This work aimed at examining anticancer, antimicrobial antioxidant aerial part (COLE). The results revealed that COLE possessed potent selective anticancer against human breast colon cancer cells. presented strong cytotoxic activity...
