The use of polymeric supports in solid-phase peptide synthesis has allowed for the facile, rapid synthesis of short peptides in a one bead/one sequence manner. This approach allows for screening peptide libraries for binding and catalytic activities. Once hits are found, the sequence of the active protein can be determined via mass spectrometry. However, problems arise when trying to create lar...

Polyamide 12 (PA 12) has been nanostructured by reactive blending with 20 wt% of a symmetric anhydride end-capped polysty-rene-b-polyisoprene (PS-b-PIP-anh) The liposome-like nanovesicles which are originally formed in the polyamide matrix (PA 12) are converted into cucumber-like coreshell nanoobjects upon increasing the volume fraction of PS by addi-j tion of homo PS of a molecular weight lowe...

Singapore Grouper Iridovirus (SGIV) is a member of nucleo cytoplasmic large DNA viruses (NCLDV). This paper reports the functional analysis of ORF75R, a major structural protein of SGIV. Immuno fluorescence studies showed that the protein was accumulated in the viral assembly site. Immunogold-labelling indicated that it was localized between the viral capsid shell and DNA core. Knockdown of ORF...

The core-shell hybrid structure is the simplest motif of two-component systems which consists of an inner core coated by an outer shell. Core-shell composite materials are attractive for their biomedical, electronic and catalytic applications in which interface between core and shell is critical for various functionalities. However, it is still challenging to study the exact role that interface...

in this study, a set of experiments were conducted to investigate the influence of edta-grafted iron oxide nanoparticles exposure on agronomic traits of sunflower (helianthus annuus) plants. the experiment was implemented by applying nano-fe3o4-edta and fe-edta fertilizers applied through spray or soil amendment. a variety of parameters including aerial organ biomass, number of leaves, plant he...

background: magnetite (fe3o4) nanoparticles are currently one of the important and acceptable magnetic nanoparticles for biomedical applications. to use magnetite nanoparticles for bacteria cell separation, the surface of nanoparticles would be modified for immobilizing of nanoparticles on the surface of bacteria. functionalization of magnetite nanoparticles is performed by different surfactant...

with the rise in the use of afm (atomic force microscope), we have witnessed a growing use of atomic microscope based nanorobots in the precise displacement of various particles. there are certain limitations to the application of nanorobots in the moving of nanoparticles. one of the most important of these limitations is the lack of an appropriate image feedback concurrent with the displaci...

in this research, the inhibitory effects of silver nanoparticles and zinc oxide nanoparticles,  in vitro, on disease stone fruits bacterial canker caused by pseudomonas syrigae pv. syringae and disease bacterial blight caused by xanthomonas arboricola pv. juglandis, were studied. different concentrations of nanoparticles were prepared on mueller hinton agar medium in two different ways in a com...

a new magnetic nanocatalyst has been prepared using immobilization of vanadate onto aminopropyl functionalized sio2/fe3o4(vo3-/nh3+-sio2/fe3o4). the obtained magnetic catalyst was characterized by ft-ir, xrd, vsm and sem techniques and used for sulfoxidation of sulfide compounds to the correspondingsulfoxides in presence of h2o2 as oxidant at room temperature. the optimum of reaction conditions...
