Erythrocyte transfusion: remedy or poison?

Colloidal gold and silver triangular nanoprisms.

It is now well-known that the size, shape, and composition of nanomaterials can dramatically affect their physical and chemical properties, and that technologies based on nanoscale materials have the potential to revolutionize fields ranging from catalysis to medicine. Among these materials, anisotropic particles are particularly interesting because the decreased symmetry of such particles ofte...

Effect of colloidal silver nanoparticles and silver nitrate on hematological indices of Zayandehrud Chub (Petroleuciscus esfahani)

Effects of different concentrations of silver nanoparticles and silver nitrate on some hematological indices of Zayanderud Chub (Petroleuciscus esfahani) were investigated. One hundred individuals of the fish (average weight 26.4 ± 1.3 g) were divided into 5 experimental groups, exposed to 1 or 25 µg/L of silver nano or silver nitrate or unpolluted water as control for 10 days. At the end, prim...
