the perovskite-structured la2cuo4 nanoparticles have been synthesized via an ultrasonic-assisted co-precipitation route using octanoic acid as organic surfactant, and the phase composition, morphology, lattice parameters and size of nanoparticles are characterized through fourier transform infrared spectroscopy, x-ray diffraction, scanning electron microscopy and transmission electron microscop...

Self-assembled polymeric nanoparticles modified with targeting ligands on the surface provide a means for localized cell delivery. To gain greater insight into the possibility of derivatizing poly(2-methyl-2-carboxytrimethylene carbonate-co-D,L-lactide) (poly(TMCC-co-LA)) nanoparticles using the Huisgen's 1,3 dipolar cycloaddition reaction, we synthesized amphiphilic copolymers comprising a hyd...

Advances in nanotechnology have led to the design of multifunctional nanoparticles capable of cellular imaging, targeted drug delivery, and diagnostics for early cancer detection. We synthesized poly(lactic-co-glycolic acid) nanoparticles encapsulating a model radiosensitizing drug docetaxel accomplishing localized in situ delivery of the sensitizer to the tumor site. The synthesized nanopartic...
