Molecular transport through nano-sized multipores of lipid vesicles: a COMSOL simulation study
Biomembranes regulate molecular transport essential to cellular function and numerous biomedical applications, such as drug delivery and gene therapy. This study simulates molecular transport through nano-sized multipores in Giant Unilamellar Vesicles (GUVs) using COMSOL Multiphysics. We analyzed the diffusion dynamics of fluorescent probes—including Calcein, Texas-red dextran 3000 (TRD- 3k), TRD- 10k, and Alexa Fluor-labeled soybean trypsin inhibitor (AF-SBTI)—across different pore sizes, and derived rate constants using curve fitting that closely align with experimental data. Additionally, an analytical model based on Fick’s law of diffusion provides further insight into transport efficiency. This approach offers a novel perspective by examining simultaneous transport through multiple nanopores, which better mimics realistic biological environments compared to traditional single-pore studies. We used COMSOL for efficiently simulating large-scale, multi-nanopore systems, particularly in biomedical applications where modeling of complex transport phenomena is essential. This work provides new insights into multipore-mediated transport, critical for optimizing nanopore-based drug delivery and advancing the understanding of cellular transport mechanisms.
期刊介绍:
The journal publishes papers in the field of biophysics, which is defined as the study of biological phenomena by using physical methods and concepts. Original papers, reviews and Biophysics letters are published. The primary goal of this journal is to advance the understanding of biological structure and function by application of the principles of physical science, and by presenting the work in a biophysical context.
Papers employing a distinctively biophysical approach at all levels of biological organisation will be considered, as will both experimental and theoretical studies. The criteria for acceptance are scientific content, originality and relevance to biological systems of current interest and importance.
Principal areas of interest include:
- Structure and dynamics of biological macromolecules
- Membrane biophysics and ion channels
