Targeted Delivery Systems
Targeted Delivery Systems
Precision drug delivery aims to transport therapeutic agents selectively to diseased tissues or target cells while minimizing systemic toxicity and off-target effects. Polyethylene glycol (PEG) has become a foundational material in modern delivery systems due to its exceptional hydrophilicity, biocompatibility, and versatile functionalization capabilities. PEGylation improves drug solubility, prolongs circulation time, enhances nanoparticle stability, reduces immunogenicity, and enables controlled targeting strategies across a broad range of therapeutic modalities.
BIOMATRIK provides a comprehensive portfolio of PEGylation reagents, PEG-lipids, and functional PEG linkers engineered for advanced drug delivery and therapeutic formulation.

Stealth PEGylation for Nanoparticle Drug Delivery
PEGylation is widely used to improve the pharmacokinetic behavior of nanoparticles, liposomes, and therapeutic payloads. PEG-coated delivery systems resist protein adsorption and immune recognition, enabling prolonged circulation and improved passive targeting through enhanced permeability and retention (EPR) effects.
Key products: DSPE-PEG, DMG-PEG, mPEG-Lipids, PEGylated Nanocarrier Components
PEG-Lipids for Vaccines & RNA Therapeutics
PEGylated lipids are critical components in modern vaccine and nucleic acid delivery technologies. These materials stabilize lipid nanoparticles and facilitate efficient delivery of mRNA, siRNA, plasmid DNA, and protein therapeutics while reducing aggregation and improving systemic stability.
Key products: DSPE-PEG-Maleimide, Ionizable PEG-Lipids, Azide-PEG-Lipids, DBCO-PEG-Lipids
Targeted Delivery Through Functional PEG Linkers
Heterobifunctional PEG linkers enable dual conjugation strategies by connecting therapeutic payloads with targeting ligands such as antibodies, peptides, or small molecules. These site-specific conjugation systems improve selective accumulation at disease sites and support the development of advanced targeted therapeutics.
Key products: Maleimide-PEG-NHS, NHS-PEG-Azide, PEG-Amine, PEG-Carboxylic Acid
Controlled Drug Release & Responsive Delivery Systems
Advanced PEG linker architectures enable precise control over payload release kinetics. Cleavable and stimuli-responsive PEG systems can be engineered to respond to pH, redox conditions, enzymes, or other biological triggers, supporting sustained and controlled therapeutic delivery.
Key products: Cleavable PEG Linkers, Disulfide PEGs, pH-Sensitive PEG Linkers
