Microstructured Dextran Hydrogels for Sustained Release of PEGylated Protein Drugs

Hydrogels have gained significant attention as ideal delivery vehicles for protein drugs. However, the use of hydrogels for protein delivery has been restricted because their porous structures inevitably cause a premature leakage of encapsulated proteins. PEG Hydrogels in Biomedical Applications A simple yet effective approach was recently reported to regulate the protein release kinetics of […]

The Stealth Properties of PEG-Coated Nanoparticles are Dependent on the PEG Grafting Densities

The Lai lab at UNC Chapel Hill published an article in Molecular Pharmaceiuticals – Evading Immune Cell Uptake and Clearance Requires PEG Grafting at Densities Substantially Exceeding the Minimum for Brush Conformation. Mol. Pharmaceutics, 2014, 11 (4), pp 1250–1258, DOI: 10.1021/mp400703d. Exploration in PEG Grafting This paper critically pointed out: Coating nanoparticles with polyethylene glycol […]

How Pegylated Drugs are Aiding Rheumatology

PEG Therapy Since PEG molecules bind to amino acids to target proteins, they are now being used in the Rheumatology field. For patients with Rheumatoid Arthritis who do not respond to standard treatment, the use of TNF-a inhibitors have been used as an alternative treatment. Positive signs with using this alternative treatment with a reduction […]

What is Chitosan and How Do We Use it?

Polysaccharide Product It turns out that shellfish are much more than delicious appetizers or entrees at our seafood restaurant. Scientists can take sugar from the hard outer skeleton of shellfish, including crab, lobster, and shrimp and use it in medicine! This sugar is called chitosan, and it has a variety of great uses. It can […]

Important Applications For Quantum Dots

Quantum Dots Semiconductor nanocrystals, also known as quantum dots, have a wide range of applications for many industries. Two of the most important applications for them are ink and in the medical industry. The particles emit distinctly different colors when they are reduced in size, and can be incorporated in materials as a sort of […]

How PEGylation can help Growth Hormone Deficiency (GHD)

Pegylation Pegylation has achieved reasonable success on the market thus far: approximately one dozen PEGylated pharmaceuticals are currently on the market with FDA approval. One of those has been instrumental in fighting the deleterious effects of Growth Hormone Deficiency. Peg acrylate More commonly recognized as a banned substance in professional sports, Human Growth Hormone (HGH) […]
