"Green" Nanotechnologies: Synthesis of Metal Nanoparticles


The main methods for nanoparticle production are chemical and physical approaches that are often costly and potentially harmful to the environment. The present review is devoted to the possibility of metal nanoparticle synthesis using plant extracts.

Progressive aggregation of Tomato yellow leaf curl virus

Czosnek, 1998) we have shown that TYLCV CP aggregation is slower in R than in S plants. Moreover the aggregation process can be modified by experimentally changing the plant phenotype from resistant to susceptible, and from susceptible to resistant. 2. Materials and methods 2.1.

Thus the SPR technique is (ii) gold treated with KNCS; (iii) gold treated in recommended for the detection of plant viruses series with KNCS and with immobilized protein in samples and can be used for rapid diagnosis A S. aureus. It was shown that the antibodies to of virus diseases of plants.


Plant viruses are widespread and economically important plant pathogens. Virtually all plants that humans grow for food, feed, and fiber are affected by at least one virus. It is the viruses of cultivated crops that have been most studied because of the financial implications of the losses they incur.

reduce virus concentration on the seeds. Few methods have been reported to treat seed and protect plants from viruses, such as use of Acinetobacter strain KNF2022T isolated from tobacco plant roots, which showed inhibi-tory effects on Tobacco mosaic virus (TMV) (Lee et al., 2009), and Enterobacter asburiae, which induced resis-

Serology Applied to Plant Virology InTech Open

Although different variations of this serological technique have been developed, the direct and the indirect ELISA (Figure 3) are the most frequently used methods for diagnosis of plant virus diseases (Almeida & Lima, 2001; Clark & Bar-Joseph 1984; Cooper &

Virus Particle Characterization UvA

Literature study: Virus Particle Characterization Page 9 of 51 Ewoud van Tricht VIROSOMES A virosome is a virus-like particle used as vaccine delivery system that can be used to initiate the body's immune system without using living or synthetically produced microorganisms like viruses.

Disease outbreaks in plant-vector-virus models with vector

While feeding on host plants, viruliferous insects serve as vectors for viruses. Successful viral transmission depends on vector behavior. Two behaviors that impact viral transmission are vector aggregation and dispersal.

Viruses | Free Full-Text | Virus-Induced Aggregates in

The role of aggregation in the context of a specific virus is often poorly understood, especially in the case of plant viruses. The aggregates are utilized by viruses to house a large complex of proteins of both viral and host origin to promote virus replication, translation, intraand intercellular transportation.

Size distribution analysis of influenza virus particles


Sep 23, 2016· Size exclusion chromatography is a standard method in quality control of biopharmaceutical proteins. In contrast, vaccine analysis is often based on activity assays. The hemagglutination assay is a widely accepted influenza quantification method, providing no insight in the size distribution of virus particles.

Purification of plant-derived anti-virus mAb through

The main goal of this research was to determine optimum pH conditions for coupling between protein A and epoxy-activated Sepharose beads for purification of monoclonal antibodies (mAbs) expressed in plants. To confirm the effect of pH conditions on purification efficacy, epoxy-activated agarose beads were coupled to protein A under the pH conditions of 8.5, 9.5, 10.5, and 11.5 (8.5R, 9.5R, 10

The plant material should be fertile i.e. in flower or fruit (both if possible), as these characteristics are often vital for identification. This might entail returning to

Impact of Virus Aggregation on Inactivation by Peracetic

Viruses in wastewater and natural environments are often present as aggregates. The disinfectant dose required for their inactivation, however, is typically determined with dispersed viruses. This study investigates how aggregation affects virus inactivation by chemical disinfectants. Bacteriophage MS2 was aggregated by lowering the solution pH, and aggregates were inactivated by peracetic
