#1 Potential of Unilamellar Liposomes as Delivery Vesicles Using Saccharomyces cerevisiae
Thalma Wahab, Félice Schreuder
Biology Program, School of Health Sciences, Stephens College
Abstract:
Fluorescein‑encapsulated liposomes play a vital role in research as they allow visualization of cellular uptake in tissues and cells. These microscopic vesicles have shown significant promise in improving stability, efficacy, and targeting of therapeutic agents. However, their performance is impacted by factors such as pH, temperature, and preparation methods. This quantitative study explores the potential of unilamellar liposomes as delivery vesicles in Saccharomyces cerevisiae (yeast). Liposomes were prepared using a 1:1 ratio of distearoylphosphatidylcholine (DSPC) and cholesterol via thin‑film hydration with probe sonication. A fluorescein release assay using Triton X‑100 was used to assess encapsulation efficiency across three experimental groups. Preliminary expectations indicate membrane disruption decreases in the presence of buffer and yeast cells. These findings contribute to understanding liposome stability for drug delivery applications such as vaccines, antimicrobial delivery, and gene therapy.
