Silver nanoparticles (AgNPs) are metal structures at the nanoscale. AgNPs have exhibited antimicrobial activities against fungi and bacteria; however synthesis of AgNPs can generate toxic waste during the reaction process. Accordingly, new routes using non-toxic compounds have been researched. The proposal of the present study was to synthesize AgNPs using ribose as a reducing agent and sodium ...

Two-dimensional electrophoresis, with isoelectric focusing in the first dimension and sodium dodecyl sulfate/polyacrylamide gel electrophoresis in the second, has been adapted for the high-resolution analysis of cerebrospinal fluid proteins. Proteins were detected with a new, highly sensitive silver stain that made visible more than 300 polypeptides from 60 microL of spinal fluid, in highly rep...

Persistent colonic inflammation increases risk for cancer, but mucosal appearance on conventional endoscopy correlates poorly with histology. Here we demonstrate the use of a flexible silver halide fiber to collect mid-infrared absorption spectra and an interval model to distinguish colitis from normal mucosa in dextran sulfate sodium treated mice. The spectral regime between 950 and 1800 cm(-1...

The protein IAs of serum-sensitive (FA635) and serum-resistant (FA638) transformants of Neisseria gonorrhoeae, which have identical pedigrees, have been shown to be different by the use of a monoclonal antibody and were also shown to be different by proteinase K cleavage and primary structural and surface peptide mapping. The difference in structure is within the surface-exposed region of the m...

The nanoparticles used in this study were prepared from AgNO3 using NaBH4 in the presence of capping agents such as citrate, sodium dodecyl sulfate, and polyvinylpyrrolidone. The formed nanoparticles were characterized with UV-Vis, TEM, and XRD. The generation of silver nanoparticles was confirmed from the appearance of yellow colour and an absorption maximum between 399 and 404 nm. The produce...

Nanofibers containing silk fibroin (SF), chondroitin sulfate (CS) and silver sulfadiazine (SSD) were made up through electrospinning technique, to produce new dressings with the potential control wound infections. Poly (ethylene oxide) (PEO) was added acidic water solution used for improve electrospinnability. Fibers characterized by scanning electron microscopy (SEM), Fourier transform infrare...
