the aim of this study was to develop a novel multifunctional nanoparticle, which encapsulates spion and gemcitabine in plga±peg to form multifunctional drug delivery system. for this aim, super paramagnetic iron oxide nanoparticles (spions) were synthesized and encapsulated simultaneously with gemcitabine (gem) in plga±peg copolymers via w/o/w double emulsification method. optimum size and enca...

Nanoscale dynamic heterogeneities in synthetic polymer solutions are detected using super-resolution optical microscopy. To this end, we map concentration fluctuations in polystyrene-toluene solutions with spatial resolution below the diffraction limit, focusing on critical fluctuations near the polymer overlap concentration, c*. Two-photon super-resolution microscopy was adapted to be applicab...

One of the most undesirable properties concrete is that cracks due to many reasons including shrinkage and applied loads. Normal has tendency seal these on its own utilizing un-hydrated cement particles deposited fine particles. This a very limited success deal with live expanding cracks. study helps by using Ultra-High Absorbent Polymer (UHAP). polymer absorbs large quantity water form gel-lik...

Schlievert et al. recently reported that the increased number of cases of toxic shock syndrome (TSS) observed by their surveillance group over the last 4 years in the Minneapolis-St. Paul metropolitan area is consistent with Centers for Disease Control and Prevention findings of an 18% increase in the incidence of TSS from 2002 to 2003 (3). He wisely cautioned medical practitioners and women us...
