CuPt/Ag trimetallic alloy nanoparticles (NPs) were synthesized by co-sputtering onto liquid polyethylene glycol (PEG), using a CuPt target and an Ag target.

One of the major obstacles in the development of ligand-targeted liposomes is poor liposome circulation longevity as a result of antibody-mediated elimination of these highly immunogenic carriers. Because studies from our laboratory suggest that it is not possible to reduce the immunogenicity of ligand-conjugated liposomes by using surface-grafted poly(ethylene glycol) (PEG), we investigated th...

The purpose of this study is to fabricate the polyethylene glycol matrix tablet by mold technique. Indomethacin and hydroxypropylmethylcellulose were used as model drug and polymer, respectively, in PEG matrix system. The physical and drug release characteristics of developed matrix tablet were studied. This inert carrier system comprising 7:3 polyethylene glycol 4000: polyethylene glycol 400 c...

Affinity-based cell separation is label-free and highly specific, but it is difficult to efficiently and gently release affinity-captured cells due to the multivalent nature of cell-material interactions. To address this challenge, we have developed a platform composed of a capture substrate and a cell-releasing molecular trigger. The capture substrate is functionalized with a cell-capture anti...

The self-assembly in aqueous solution of benzene-1,3,5-tricarboxamide (BTA) bearing one alkyl chain and two PEG (polyethylene glycol) chains or yields molecular-packing driven nanostructures.

The objective of the present study was to evaluate the effect of different plasticizers on the ethylcellulose coatings of capsules and its timed release characteristics. Various plasticizers such as dibutyl phthalate (DBP), triacetin (TA), glycerol, triethyl citrate (TEC), polyethylene glycol-4000 and polyethylene glycol-6000 (PEG) were studied. The physicochemical properties of the casted poly...

Nano-sized γ-Al2O3 was synthesized successfully by a simple method using Al2(SO4)3·18H2O as aluminium source and in the presence of polyethylene glycol (PEG 2000). FTIR spectroscopy, X-ray diffraction (XRD), scanning electron microscope (SEM) and transmission electron microscope (TEM) were used to characterize the structure and morphology of synthesized powder. The results showed that PEG playe...

BACKGROUND: Constipation is one of the common problems in childhood and consists of 3% of referrals to pediatricians and 25% of pediatric gastroenterologists. Aperients are common alternatives for treating chronic constipation. The present study aimed to compare the efficacy of three laxatives [polyethylene glycol (PEG), magnesium hydroxide, and lactulose]. METHODS: In this randomized clinical ...

Graphene oxide (GO) is a hotspot, especially in the field of biomedical. However, the clinical application of GO is still faces a lot of challenges. In order to improve the solubility and biocompatibility of GO, polyethylene glycol (PEG) was grafted on the surface of graphene oxide by amide reaction. PEGylated graphene oxide (PEG-GO) was characterized using Fourier transform infrared spectrosco...

This study first reports the pharmacokinetic disposition of polyethylene glycol (PEG)-modified salmon calcitonin (sCT) based on the number of attached PEG molecules. PEG-modified sCT was prepared by covalent linkage with succinimidyl carbonate monomethoxy polyethylene glycol. Mono- and di-PEG-sCTs were separated by size exclusion and reverse phase HPLC, and radioiodinated by the chloramine-T me...
