Capuli cherry-mediated green synthesis of silver nanoparticles under white solar and blue LED light

Fabrication of silver nanoplates using Nephelium lappaceum (Rambutan) peel: A sustainable approach

“…3) and the corresponding size is slightly deviated with the TEM image results. This is due to the screening of small particles by bigger ones and also the presence of unreacted phytochemicals of RPE in a reaction mixture [24]. intensities of (111) and (200) diffraction peaks is higher than the conventional value (4.5 times).…”

Improvement of Cochineal Extract (Dactylopius coccus Costa) Properties Based on the Green Synthesis of Silver Nanoparticles for Application in Organic Devices

“…is solution was evaporated using a Rotavapor (Buchi R-220) at 40°C and a pressure of 44000 Pa before being vacuum-filtered (a filter paper of 0.45 μm). For the reduction of AgNO 3 , the pigment was diluted with NaOH to obtain a pH of 12 [9]. For the biosynthesis of AgNPs, different volumes (0.1 ml and 0.4 ml) of the alkaline solution (cochineal at pH 12) were diluted with 1 ml of AgNO 3 solution (10 mM; pH � 5.6), and this mixture was incubated for 1 h at 40°C.…”

“…To improve the optical and electrical properties of cochineal, it was used as the reducing agent during the biosynthesis of silver nanoparticles (AgNPs) without submitting the cochineal to any kind of separation of its primary compounds. e cochineal extract was used as the reducing agent for the biosynthesis of AgNPs, since green synthesis of the AgNPs has been an easy, affordable, inexpensive technique and is potentially not harmful to human health and the environment [9][10][11][12][13][14]. Different volumes of cochineal dye (pH � 12, [5]) in 1 ml of AgNO 3 solution (10 mM, pH � 5.6) were analyzed with UV-Vis spectrometry, Commission Internationale de l'Eclairage (CIE) chromaticity diagram, cyclic voltammetry (CV), scanning transmission electron microscopy (STEM), energy dispersive X-ray spectroscopy (EDS), dynamic light scattering (DLS), and X-ray diffraction (XRD).…”

Photobiologic-mediated fabrication of silver nanoparticles with antibacterial activity

“…Production of AgNPs was optimized by testing various levels of pH (2, 3, 4, 5, 6, 7, 8, 9, and 10) and different concentrations of DCRE (1,2,3,4,5,6,7,8,9, and 10 mL) and metal ion (0.1, 0.2, 0.3, 0.4, 0.5, 0.6, 0.7, 0.8, 0.9, and 1.0 mmol). The stability of the obtained nanoparticles was analyzed by exposing them to ambient conditions for several months.…”

“…In response to the emergence of new bacterial pathogens and the development of resistance to existing antibiotics, biomedical researchers and pharmaceutical companies are extensively studying the antibacterial properties of metallic nanoparticles against various microbial pathogens [1][2][3]. Among several biological metal nanoparticles that have been studied as antibacterial agents, silver nanoparticles play a key role in inhibiting most bacterial pathogens [4,5].…”
