Exploring Graphene Oxide–Cholesterol Interactions Across Model Membranes

Sunghee Lee • February 23, 2026

We’re pleased to announce our new collaborative publication, “Study of the Interaction Between Graphene Oxide and Cholesterol Using Different Artificial Membrane Models,” conducted in partnership with colleagues in Italy.


This work investigates how graphene oxide—an emerging nanomaterial with biomedical promise—interacts with cholesterol within lipid membranes. By employing various artificial membrane systems, we examined how membrane composition and organization influence these interactions, revealing key insights into the physicochemical mechanisms at play.


Our results contribute to a deeper understanding of how nanomaterials engage with biological membranes, providing valuable guidance for the safe and effective design of graphene-based biomedical applications.


Congratulations to all team members and our Italian collaborators on this exciting achievement! The full article is available here: https://www.sciencedirect.com/science/article/pii/S0021979726002821.

New Insights into Serotonin’s Relationship with Cell Membranes

By Sunghee Lee • February 23, 2026
In this study, we explored how the membrane environment shapes the behavior of serotonin, a key neurotransmitter involved in mood regulation and neural signaling. By systematically varying lipid composition in model membranes, we uncovered how differences in lipid charge, fluidity, and packing influence serotonin’s nonspecific interactions with bilayers. Our findings shed new light on the physical chemistry of neurotransmitter–membrane interactions, with potential implications for understanding serotonin’s diverse physiological functions and its role in receptor signaling. Congratulations to all co-authors for their outstanding work and collaboration! The article can be accessed here: https://pubs.acs.org/doi/full/10.1021/acsptsci.5c00767

Recent Publication: How Tiny Molecules Shape the Flexibility of Cell Membranes

By Sunghee Lee • November 15, 2025
Our research team has uncovered new details about how small oil-like molecules influence the thickness and flexibility of cell membranes. These membranes, built from layers of lipids, contain tiny pockets of free space that help control how soft, dense, or permeable the membrane is. Our research team found that some smaller molecules can fit into these layers, making the membrane thicker, while larger or crystallizing ones get pushed out, leading to thinning. These changes help explain how different molecules inside a membrane affect its overall structure and function. This study not only expands our understanding of how biological membranes work but also points to new possibilities for creating custom-designed synthetic membranes for research and technology.

Bacterial Membranes Meet PFAS: New Findings from the Project Symphony Lab

By Sunghee Lee • September 2, 2025
We are absolutely thrilled to announce that our Project Symphony, undergrad-fueled research team, just published another article digging into how those stubborn “forever chemicals”, called perfluoroalkyl substances, or PFAS, can mess with model bacterial membranes, making them leakier and less organized than before. It is alarming to discover that these chemicals actively change the physical properties of membranes, and different types of lipids respond in their own way to the disruption, meaning some bacteria could be more affected than others. What makes this work even more special is that our undergraduate team handled every step, and it’s now out there as open access for everyone to read—proof that curiosity and teamwork can lead to great science. The article is appeared in ACS Omega (on August 26, 2025), a publication of American Chemical Society (ACS). Please explore the article here: " Membrane-Modifying Effects of Perfluoroalkyl Substances in Model Bacterial Membranes " https://pubs.acs.org/doi/10.1021/acsomega.5c04177 Congratulations to Micaela, Amani, Jasmin, Jessica, Lizzy, Joey, and Jacqui for their enthusiasm and hard work leading to this contribution! Project Symphony’s journey continues—stay tuned for what’s next.
