In the evolving landscape of nanomedicine and drug delivery, albumin nanoparticles (ANPs) have emerged as a powerful platform for enhancing drug solubility, improving bioavailability, enabling targeted delivery, and extending drug half-life. Given albumin’s biocompatibility, biodegradability, and natural affinity for tumor tissues, ANPs are being actively developed for oncology, RNA therapeutics, protein/antibody delivery, and vaccine applications.  As a global leader in advanced drug delivery systems, Litchlab has pioneered a next-generation albumin nanoparticle platform, designed to optimize drug loading, control release kinetics, and improve therapeutic efficacy while minimizing systemic toxicity.  

Core Advantages of Litchlab’s Albumin Nanoparticle Technology

1. High Drug Loading and Enhanced Solubility  

Albumin has multiple hydrophobic and hydrophilic binding domains, making it an ideal nanocarrier for poorly soluble small molecules, biologics, and nucleic acid therapeutics.  Through proprietary albumin crosslinking and nanoparticle formulation techniques, Litchlab achieves:  

>80% drug loading efficiency for small molecule chemotherapeutics (e.g., paclitaxel, docetaxel), significantly improving solubility;  

Stable encapsulation of protein and antibody drugs, maintaining bioactivity and extending circulation time;  

Enhanced delivery of RNA therapeutics (siRNA, mRNA, ASO), protecting them from degradation and improving cellular uptake.  

2. Targeted Drug Delivery via EPR Effect & Active Targeting  

Litchlab’s albumin nanoparticle system exploits both passive and active targeting mechanisms to maximize drug accumulation in diseased tissues.  

(1) Passive Targeting: Leveraging the Enhanced Permeability and Retention (EPR) Effect

Tumor tissues exhibit leaky vasculature and impaired lymphatic drainage, allowing albumin nanoparticles to accumulate preferentially in tumor sites, thereby increasing local drug concentration while minimizing systemic toxicity.  

(2) Active Targeting: Receptor-Mediated Transport  

Certain cells, especially in tumors, overexpress albumin receptors (gp60, SPARC), facilitating:  

Increased drug uptake via receptor-mediated endocytosis;  

Enhanced transendothelial transport for deeper tumor penetration;  

Improved therapeutic selectivity, reducing off-target effects.  

Litchlab further enhances targeting capabilities by functionalizing albumin nanoparticles with antibodies, peptides, or aptamers, enabling precision drug delivery to specific diseased cells.  

3. Controlled Drug Release: Optimizing Therapeutic Index & Reducing Toxicity  

Litchlab’s albumin nanoparticle platform features tailored drug release kinetics, allowing for:  

Sustained release – suitable for chronic disease treatments, reducing dosing frequency;  

Stimuli-responsive release (pH, enzyme-triggered) – ideal for tumor and inflammation sites, ensuring localized activation;  

Pulsatile release – effective for vaccines and gene therapies, enhancing immune response or gene expression.  

4. Versatile Platform for Multiple Drug Modalities  

Litchlab’s albumin nanoparticle technology is compatible with a broad range of therapeutics, including small molecules, biologics, and gene therapies.  

Clinical Applications of Litchlab’s Albumin Nanoparticle Technology
