Parabens are substances used in the food, pharmaceutical and cosmetic industries. Recent studies have indicated that these toxic potential, cause endocrine disruption can easily bioaccumulate; therefore, their physicochemical properties of industrial, biological environmental interest. Due to potential use development more efficient cleaner processes, design recovery strategies reasonable desig...

Polymeric micelles are assemblies of synthetic polymers and have been studied and developed as drug carriers for targeting. Polymeric micelles are composed of the inner core and the outer shell, and typically form from AB-type block copolymers in which two polymer blocks are connected in a tandem form. Polyethyleneglycol (PEG) has been most commonly used as one polymer block composing the outer...

The effect of hydrocarbon chain length on chemical selectivity in micellar electrokinetic chromatography (MEKC) was investigated using polymeric sulfated surfactants: poly-(sodium 7-octenyl sulfate), poly(sodium 8-nonenyl sulfate), poly(sodium 9-decenyl sulfate), and poly(sodium 10-undecenyl sulfate). Linear solvation energy relationships (LSERs) and free energy of transfer studies were conduct...

We developed the novel polymeric prodrugs synthesized by mechanochemical solid-state copolymerization of glucose-based polysaccharides (dextran orglycogen) and the methacryloyloxy derivative of 5-fluorouracil (5-FU). The copolymerization proceededreadily and each polymeric prodrug was quantitatively obtained within8 h reaction. The number average molecular weight (Mn) and polydispersity (H) of ...

The nanostructured anatase TiO2 with high thermal stability was prepared by polymeric sol-gel method without any additives. The particle size distribution of polymeric titania sol was determined by dynamic light scattering (DLS). Then properties of obtained titania were investigated by TG-DTA, XRD, FESEM and TEM. Also, the decolorization capability of resultant anatase was evaluated using methy...

Fluorescent polymeric assemblies and nanoparticles (NPs) of nanoscale dimensions have become a focus of intensive investigations during the past few decades due to combined advantages such as improved biocompatibility, water dispersibility, stimuli-responsiveness, facile integration into optical detection devices, and the ability of further functionalization. In addition, the chemical compositi...

The development of polymeric luminescent nanomaterials for biomedical applications has recently attracted a large amount of attention due to the remarkable advantages of these materials compared with small organic dyes and fluorescent inorganic nanomaterials. Among these polymeric luminescent nanomaterials, polymeric luminescent nanomaterials based on dyes with aggregation-induced emission (AIE...

conventional transdermal drug delivery systems (tdds) have been designed for drug delivery through the skin. these systems use the permeability property of stratum corneum, the outermost surface layer of the skin. applying polymeric micro and nanofibers in drug delivery has recently attracted great attention and the electrospinning technique is the preferred method for polymeric micro-nanofiber...

acrylic-type polymeric systems having degradable ester bonds linked to ibuprofen were synthesized and evaluated as materials for drug delivery. ibuprofen, as a non-steroidal anti-inflammatory drug, was linked to 2-hydroxyethyl methacrylate by activated ester methodology in one-pot procedure. the resulting methacrylic derivative of ibuprofen was copolymerized with 2-hydroxyethyl methacrylate and...
