Aqueous extract of shade dried leaves of Euphorbia hirta (L) was used for the synthesis of silver (Ag) nanoparticles. UV-visible spectroscopy studies were carried out to assess the formation Ag nanoparticles. Scanning Electron Microscopic (SEM) was used to characterize the Ag nanoparticles. SEM image divulges that silver nanoparticles are quite polydispersed, the size ranging from 40 nm to 50 n...

Supplementary Figure 1. Fullerence has poor solubility in water while the C60S and LC60S nanoparticles can be stably dispersed in water. (a) A typical photograph of fullerence (C60), C60S nanoparticles, and LC60S nanoparticles in deionized water (2 mg ml-1). The C60S and LC60S nanoparticles can be well dispersed in deionized water while fullerene forms aggregates and sinks down at the bottom of...

We report a novel, facile and general approach, in situ nanopressing, to integrate nanoparticles and polymers in a thin film configuration, where both nanoparticles exposure and film robustness are indispensable for applications. By simply pressing silica nanoparticles into a polymer thin film under an external force, we successfully attained a nanoparticles-polymer thin film, where the silica ...

extracellular extract for the synthesis of silver nanoparticles using AgNO3. The formation of nanoparticles was confirmed by different methods, such as UV-Vis absorption spectroscopy, XRD, FTIR, EDX, and TEM analysis. The formation of silver nanoparticles (AgNPs) was confirmed by the change in color from light yellow to dark brown. The absorbance peak obtained at 430 nm confirmed the presence o...

Emergence of resistant microbes to conventional antibiotics and increased emphasis on health-care costs has raised the concern for the development of new effective antimicrobial reagents. Silver nanoparticles being an excellent broad-spectrum antibacterial agent could be considered as a suitable alternative for existing antibiotic. This study demonstrates the extra-cellular synthesis of stable ...

Nanotechnology refers to research and technology development at the atomic, molecular, and macromolecular scale, leading to the controlled manipulation and study of structures and devices with length scales in the 1-100 nanometers range. Objects at this scale, such as “nanoparticles,” take on novel properties and functions that differ markedly from those seen in the bulk scale. The small size, ...
