A Reactive Poly(ethylene glycol) Layer To Achieve Specific Surface Plasmon Resonance Sensing with a High S/N Ratio: The Substantial Role of a Short Underbrushed PEG Layer in Minimizing Nonspecific Adsorption

Analytical Chemistry, 2005
A reactive poly(ethylene glycol) (PEG)-brushed layer was constructed on a surface plasmon resonance (SPR) sensor chip using a heterobifunctional PEG possessing an acetal group at one end and a mercapto group at the other end (alpha-acetal-omega-mercapto ...

Cross-Sectional PEG Ratios, Market Equity Premium, and Macroeconomic Activity [PDF]

SSRN Electronic Journal, 2012
This article explores the information content of PEG ratios (price/earnings to growth ratios) for future aggregate returns and economic fundamentals. We first establish an analytic link between PEG ratios and time-varying expected returns of stocks. We then combine the link with empirical asset pricing models to extract market-wide information from ...

Specific effects of PEGylation on gene delivery efficacy of polyethylenimine: interplay between PEG substitution and N/P ratio.

Acta Biomaterialia, 2012
While an effective non-viral gene carrier, 25 kDa branched polyethylenimine (PEI) is cytotoxic, and decreasing its toxicity while maintaining its functionality is vital. Conjugation of carriers with polyethylene glycol (PEG) is a common approach to decreasing toxicity and improving biodistribution; however, the effect of PEGylation on PEI transfection ...

Enhancing the Sensitivity of DNA and Aptamer Probes in the Dextran/PEG Aqueous Two-Phase System.

Analytical Chemistry, 2021
Increasing the local concentration of DNA-based probes is a convenient way to improve the sensitivity of biosensors. Instead of using organic solvents or ionic liquids that phase-separate with water based on hydrophobic interactions, we herein studied a ...

PEG Ratios

The Journal of Investing, 2003
High price-earnings ratios are often justified by high growth rates in corporate earnings. In recent years, many analysts have turned to the ratio of the PE ratio to the growth rate (the PEG ratio) in an effort to control for this relationship. In fact, the PEG ratio is not a constant that can be used to decide whether a stock is cheap or not.

Effect of EDA/PEGDGE Mole Ratios on PEG-Based Hydrogel Scaffolds Properties

Advanced Materials Research, 2012
The synthesis of biocompatible hydrogel based on poly (ethylene glycol) (PEG) and ethylene diamine (EDA) using epoxy-amine chemistry was conducted. PEG was chosen as the base material (or monomer) to synthesise hydrogels in this study due to its high hydrophilicity, biocompatibility and low toxicity properties.

PEG polymer brushes via the Langmuir–Schaefer technique: The transfer ratio

Journal of Colloid and Interface Science, 2013
The Langmuir-Schaefer technique allows horizontal transfer of monolayer films of amphiphilic molecules from an air-water interface to a hydrophobic solid substrate. Spectroscopic ellipsometry has been used to estimate the transfer ratio of Polyethylene Glycol (PEG) polymer brushes prepared by this Langmuir-Schaefer method.

Thermal and rheological behavior of PEG-based nanocomposites: Effect of filler aspect ratio and size

AIP Conference Proceedings, 2018
In this work, polyethylene glycol (PEG) nanocomposites containing different nanofillers (namely boehmites and hydrotalcites) were prepared through melt compounding and their thermal and rheological behavior was thoroughly investigated. The obtained results showed that the two types of nanofillers interact in a different way with the polymer matrix ...
