Photodynamic Therapy
Precision PEG Reagents for Advanced Photodynamic Therapy
Photodynamic therapy (PDT) is a minimally invasive therapeutic strategy that combines photosensitizers, light irradiation, and molecular oxygen to generate reactive oxygen species (ROS) for selective destruction of diseased tissues. The effectiveness of PDT depends heavily on the solubility, stability, targeting capability, and controlled delivery of photosensitizers within biological systems. PEGylation technologies have become essential for optimizing PDT performance by improving biocompatibility, circulation behavior, and tumor-selective accumulation.
BIOMATRIK provides a comprehensive portfolio of high-purity PEG derivatives, PEG-lipids, and functional PEG linkers engineered for photodynamic therapy research, photosensitizer delivery, and advanced therapeutic nanomedicine.

PEGylation for Improved Photosensitizer Delivery
Many photosensitizers suffer from poor aqueous solubility, rapid clearance, and non-specific toxicity. PEGylation improves hydrophilicity and enhances pharmacokinetic behavior, enabling more efficient delivery and prolonged systemic circulation. PEG-modified photosensitizers also exhibit reduced aggregation and improved stability in biological environments.
Key products: mPEG, mPEG-NHS, PEGylated Lipids, PEG Block Copolymers
Targeted Photodynamic Therapy Through Functional PEG Linkers
Functional PEG derivatives enable precise conjugation of photosensitizers to antibodies, peptides, and targeting ligands for selective accumulation in tumor tissues or pathogenic cells. Heterobifunctional PEG linkers support modular and site-specific PDT system design while preserving biological activity.
Key products: PEG-COOH, NHS-PEG-Maleimide, Folate-PEG, Heterobifunctional PEG Linkers
Stimuli-Responsive PEG Systems for Controlled ROS Release
Responsive PEG linkers provide controlled activation and release of photosensitizers under specific biological conditions such as redox environments, pH changes, or enzymatic activity. These systems improve therapeutic precision while minimizing systemic side effects and off-target phototoxicity.
Key products: Disulfide PEG Linkers, Cleavable PEG Linkers, pH-Sensitive PEG Reagents
PEGylated Nanoplatforms for Advanced PDT
PEGylated liposomes, micelles, and nanoparticles improve photosensitizer loading, circulation stability, and tumor accumulation.
