Nanoscience Instruments invites you to their event

Screening of the Binding Affinity of Serum Proteins to mRNA-LNPs by QCM-D

About this event

Join us to hear from Federica Sebastiani, who earned her PhD in chemistry from the University of Reading, UK, in 2014. She is currently working as a Tenure Track Assistant Professor at the Department of Pharmacy, University of Copenhagen.

The focus of Prof. Sebastiani's research is on physicochemical characterization of self-assembled soft matter systems, and in particular, on lipid-based systems. She is interested in the relationship between the structure and function of lipid assembly for drug delivery, i.e. LNPs for mRNA delivery. In parallel, she is interested in studying these systems when interacting with proteins and/or model membranes. By understanding the relationship between structure and function of bio-colloids and biomimetic systems, she aims to control function by tuning structure.

Lipid nanoparticles (LNPs) are promising drug and gene carriers. Upon intravenous administration, LNPs experience different degrees of cellular uptake depending on their formulation. Currently, in vitro and in vivo studies are the gold standard for assessing the fate of nano-carriers once administered, but they are time consuming and expensive.

In this webinar, you will:

  • Learn about a time and cost-effective method to screen a wide range of LNP formulations and how to select the most promising candidates for in vitro and in vivo studies
  • Explore two different approaches to investigate the binding affinity between LNPs and serum proteins using sensor functionalization with either protein-specific antibody or PEG-specific antibody
  • Discover how sensing was conducted, using Quartz Crystal Microbalance with Dissipation (QCM-D)
  • Learn how to use this method for other surface sensing techniques such as Surface Plasmon Resonance (SPR) or ellipsometry
