We are committed to bringing you Greener Alternative Products, which adhere to one or more of The 12 Principles of Green Chemistry. Polyethylene glycol (PEG) is an eco-friendly, biodegradable polymer widely used in pharmaceuticals and cosmetics. Its non-toxic nature and versatility make it a sustainable choice, derived from renewable resources, contributing to greener product formulations. Click here for more information.

Application

Challenges in Pharmacokinetic Modelling of [(18)F]fluoro-PEG-folate PET/CT Imaging in Epithelial Ovarian Cancer Patients.: This study addresses the complexities of pharmacokinetic modeling in using Polyethylene glycol (PEG)-conjugated imaging agents for PET/CT in ovarian cancer, highlighting the adaptability and clinical implications of PEG in diagnostic imaging (Ruytenberg et al., 2024).

Assessing the toxicity of one-step-synthesized PEG-coated gold nanoparticles: in vitro and in vivo studies.: Research into the biocompatibility of PEG-coated gold nanoparticles synthesized in a single step, evaluating their safety profile across both cellular and animal models, thus underscoring PEG′s role in enhancing nanomedicine safety (Garrigós et al., 2024).

Microwave synthesized novel biomass carbon dots applied in the fluorescent detection of crystal violet.: The study explores the use of PEG in the synthesis of carbon dots for enhanced fluorescence in dye detection, offering insights into the broader applicative potential of PEG in environmental monitoring and safety (Yin et al., 2024).

Modified zero-valent iron nanoparticles enhanced remediation of PCBs-contaminated soil.: Illustrating PEG′s utility in environmental cleanup, this study details the enhancement of soil remediation techniques through the application of PEG-modified nanoparticles, reflecting PEG′s versatility across different sectors (Zhao et al., 2024).
