PEGylated Nanoparticle Technologies: Mechanisms and Therapeutic Applications – Liposome, Lipid Nanoparticle, Polymeric Micelles

PEGylated nanoparticles from liposome systems to advanced polymeric and lipid platforms tailored to specific therapeutic payloads and administration routes. Polyethylene glycol (PEG) surface modification, or PEGylation, constitutes a foundational strategy in nanomedicine for enhancing the pharmacokinetic and pharmacodynamic profiles of nanoparticle-based drug delivery systems.

How to measure molecular weights of hyaluronic acid? The three methods we use: SEC-MALS, conventional SEC and Intrinsic Viscosity methods

The molecular weight (MW) of hyaluronic acid (HA) can be determined by size-exclusion chromatography coupled with multi-angle light scattering (SEC-MALS), conventional SEC, or intrinsic viscosity. SEC-MALS provides absolute weight-average MW. Conventional SEC and intrinsic viscosity measurements provide a rapid, low-cost alternative MW estimation.

pegfilgrastim case study for 7 biosimilars – PEGylation is a mature and versatile platform for improving biopharmaceutical performance

Food and Drug Administration (FDA) has approved seven biosimilars for pegfilgrastim, the active ingredient in the reference product Neulasta (developed by Amgen). Pegfilgrastim is a PEGylated form of granulocyte colony-stimulating factor used to reduce the risk of febrile neutropenia in patients undergoing myelosuppressive chemotherapy.

Calculating the Contour Length and Hydrodynamic Radius of Polyethylene Glycol in Aqueous Solutions

This post outlines the fundamental methods for calculating the contour length—the maximum extended chain dimension—and the hydrodynamic radius, which characterizes the effective size of the solvated coil. These calculations rely on established polymer physics and empirical relations from experimental data.

Improving the Stability of Maleimide–Thiol Conjugation for Drug Targeting

Abstract Maleimides are essential compounds for drug conjugation reactions via thiols to antibodies, peptides and other targeting units. However, one main drawback is the occurrence of thiol exchange reactions with, for example, glutathione resulting in loss of the targeting ability. A new strategy to overcome such retro-Michael exchange processes of maleimide–thiol conjugates by stabilization of […]
