In the evolving field of drug delivery, polymer micelles (PMs) have emerged as a transformative platform, enhancing drug solubility, stability, and targeted delivery. Litchlab is at the forefront of this innovation, leveraging its expertise in polymer micelle-based drug delivery systems to optimize therapeutic efficacy while minimizing systemic toxicity.
Polymer micelles are self-assembling amphiphilic block copolymers that form nanoscopic core-shell structures in aqueous environments. Their unique architecture allows for:
Enhanced solubility of hydrophobic drugs, improving bioavailability
Targeted drug delivery through passive (EPR effect) and active targeting (ligand-functionalized micelles)
Controlled drug release, reducing dosing frequency and side effects
Improved stability, protecting sensitive biologics such as siRNA, mRNA, and peptides
Litchlab’s proprietary polymeric excipients (PEG-PLA, PEG-PCL, PEO-PPO-PEO triblock copolymers, etc.) enable tunable micelle structures to optimize drug loading, release kinetics, and targeting efficiency.
Litchlab employs stimuli-responsive polymer micelles that release drugs in response to pH, temperature, redox conditions, or enzymatic triggers. This approach ensures:
Site-specific activation in tumor microenvironments
Minimized off-target toxicity for chemotherapy drugs and biologics
Extended circulation time for sustained therapeutic effects
Litchlab’s polymer micelles can be surface-modified with targeting ligands (antibodies, peptides, aptamers) to enhance cellular uptake and tissue specificity. This is particularly valuable for:
Oncology – Encapsulation of hydrophobic chemotherapeutics (paclitaxel, doxorubicin) to improve tumor accumulation
Gene Therapy – Protection and delivery of siRNA, mRNA, and CRISPR/Cas9 sys tems, improving transfection efficiency
Peptide & Protein Delivery – Overcoming enzymatic degradation challenges for biologics
Therapeutic Area | Application | Advantage |
Oncology | Chemotherapy drug encapsulation (paclitaxel, doxorubicin) | Increased tumor accumulation, reduced systemic toxicity |
RNA Therapeutics | siRNA/mRNA delivery | Protects RNA from degradation, enhances cellular uptake |
Inflammatory Diseases | Steroid & biologics encapsulation | Prolonged circulation, improved efficacy |
CNS Disorders | BBB-penetrating micelles for neurodegenerative diseases | Enables brain-targeted drug delivery |
Vaccine Delivery | Polymer micelle-based adjuvants | Enhanced immune response & stability |
