We have obtained gram quantities of clean, viable eggs of Meloidogyne incognita by a method which combined treatment with hypochlorite and differential centrifugation. Chili pepper plants (Capsicum frutescens L.) infected with M. incognita were dug at harvest from a naturally infested field. Egg sacs from roots of 50 plants were obtained by kneading the(More)
Targeted drug delivery systems are of special importance in cancer therapies, since serious side effects resulting from unspecific accumulation of highly toxic chemotherapeutics in healthy tissues can restrict effectiveness of the therapy. In this work we present the method of preparing biocompatible, polyelectrolyte nanoparticles containing the anticancer(More)
Ultrathin polyelectrolyte films containing silver nanoparticles appear to be a promising material for antimicrobial coatings used in the medical area. The present work is focused on the formation of multilayer polyelectrolyte films using: polyethyleneimine (PEI) as polycation, Poly(sodium 4-styrenesulfonate) (PSS) as polyanions and negatively charged silver(More)
Online communities play an important role in the world of contemporary social networks. Due to the ubiquitous availability of ICT tools individuals can easily form small, tight, dense groups around various topics and subjects of interest. These online communities share many similarities with general social networks, but they display some interesting(More)
Metallic monodisperse copper nanoparticles at a relatively high concentration (300 ppm CuNPs) have been synthesized by the reduction of copper salt with hydrazine in the aqueous SDS solution. The average particles size and the distribution size were characterized by Dynamic Light Scattering (DLS), Nanosight-Nanoparticle Tracking Analysis (NTA). The(More)
It is known that the light scattering from the metal particles deposited on the surfaces of cells can be used for increasing light trapping in the solar cells. In this work, plasmonic structures are composite materials that consisted of silver nanoparticles embedded in dielectric films of TiO x — used as cell antireflection coating. The films are deposited(More)
