Abstract
Aim: This study focuses on biotinylated nanocarriers designed to encapsulate amphiphilic molecules with self-biodegradable properties for enhanced drug delivery. Methods: Biotin-zein conjugated nanoparticles were synthesized and tested in C6 cell lines to evaluate their viability and cellular uptake. Optimization was achieved using a acentral composite design. The nanoparticles underwent thermogravimetric analysis, and their pharmacokinetics and biodistribution were also studied. Results: The optimized nanoparticles displayed 96.31% drug encapsulation efficiency, a particle size of 95.29nm and a zeta potential of -17.7mV. These nanoparticles showed increased cytotoxicity and improved cellular uptake compared with free drugs. Thermogravimetric analysis revealed that the drug-loaded nanocarriers provided better protection against drug degradation. Pharmacokinetic and biodistribution studies indicated that the formulation had an extended brain residence time, highlighting its effectiveness. Conclusion: The biotin-zein conjugated nanoparticles developed in this study offer a promising nano-vehicle for in vivo biodistribution and pharmacokinetic applications. Their high drug encapsulation efficiency, stability and extended brain residence time suggest they are effective for targeted drug delivery and therapeutic uses.
