Visualizing pH-induced Lipid Nanoparticle Dynamics Provide a Better Understanding of their Formation and Drug Delivery Mechanism
This is a presentation on “Single-particle microscopy of lipid nanoparticles (LNPs)”, which is achieved by applying fluorescence microscopy in combination with custom imaging techniques develops in Prof. Sabrina Leslie’s group at UBC. More specifically we use Convex Lens-induced Confinement (CLiC) microscopy, as well as Förster resonance energy transfer (FRET) and photo-bleaching measurements, to develop assays for studying LNPs. These measurements allow us to characterize biophysical properties of the LNPs, as well as their dynamics as function of changing buffer conditions (e.g. pH).

Selectivity of Protein Interactions Stimulated by Terahertz Signals
It has been established that Terahertz (THz) band signals can interact with biomolecules through resonant modes. Specifically, of interest here, protein activation. Our research goal is to show how directing the mechanical signaling inside protein molecules using THz signals can control changes in their structure and activate associated biochemical and biomechanical events. To establish that, we formulate a selectivity metric that quantifies the system performance and captures the capability of the nanoantenna to induce a conformational change in the desired protein molecule/population. The metric provides a score between −1 and 1 that indicates the degree of control we have over the system to achieve targeted protein interactions. The presented work sheds light on the potential associated with the electromagnetic-based control of protein networks, which could lead to a plethora of applications in the medical field ranging from bio-sensing to targeted therapy.

The Development of an Impedance-Based Biosensor for Early Detection of Colon Cancer
Nanomaterials functionalized with biorecognition elements that interact with analytes play an important role in a biosensor design. The purpose of this study was to determine the effectiveness of two different kinds of nanoparticles in the signal improvement in an impedance-based biosensor. In the study, we were able to effectively conjugate 13 nm gold nanoparticles and 60 nm liposomes to small metabolites, including diacetylspermine, hippuric acid and creatinine, known colon cancer biomarkers. The sensing function of these conjugates was then validated by the specific attachment to an antibody-modified electrode surface for the development of an electrochemical biosensor for detecting biomarkers for colon cancer. The conjugates, as well as modified electrodes were characterized through various analytical, spectroscopic and microscopic techniques. Analysis of the impedance results suggest which kind of conjugates, gold nanoparticles or liposomes, act as a more effective signal amplifier in this biosensor. Optimizing the performance of individual components of a sensor would result in many useful advancements for the field of biosensor development.

Novel Sulfur-Containing Lipids for the Delivery of RNA Therapeutics
Lipid nanoparticle (LNP) formulations are the leading systems for in vivo delivery of siRNA and mRNA in clinical applications. Such LNPs incorporate structurally novel ionizable lipids terminating with a tertiary amino group. In this research, we explore aspects of the structure-activity relationship of MC3, a particularly efficacious ionizable lipid for siRNA delivery. Thus, MC3 analogues wherein the double bonds are replaced with sulfur atoms were found to retain in vivo activity. This may lead to new classes of lipids with improved biological profiles.
Fariba Saadati is a Research Associate supervised by NMIN researcher Dr. Marco A. Ciufolini. She has PhD in organic Chemistry.

Single-Particle Measurements of Size and Loading for Drug-delivery Lipid Nanoparticles
To understand the drug-loading mechanism of lipid nanoparticles (LNPs) and optimize the design of LNPs, we developed a new imaging technique: Convex Lens-induced Confinement (CLiC) microscopy, which can be used to track mobilized nanoparticles with single molecule resolution over long viewing times. I will talk about how we learned the spatial distribution of silencing RNA (siRNA) drug molecules within Onpattro LNPs and offer valuable insights into the LNP structure.

Liposomal Resiquimod for Enhanced Immunotherapy of Peritoneal Metastases of Colorectal Cancer
Colorectal cancer with peritoneal metastases is currently treated by cytoreductive surgery and locoregional chemotherapeutics. This standard treatment is associated with high morbidity, mortality, and recurrence rate. To improve the efficacy of immunotherapy in treating colorectal metastasis, we used a cationic liposomal formulation to enhance localized immunotherapeutics retention in peritoneal cavity, achieving improved therapeutic outcomes. Our liposome-based delivery system contains 1,2-stearoyl-3-trimethylammonium-propane chloride (DSTAP), a cationic lipid, to localize a toll-like receptor agonist, resiquimod (R848), in the peritoneal cavity (PerC) for enhancing the immune response against cancer that had spread to the PerC.

Enhancing porphyrin intracellular delivery with next-generation porphysomes for photodynamic therapy
Porphysomes are liposome-like nanoparticles self-assembled and composed of a high density of porphyrin-lipid conjugates, allowing for their application in imaging and photonic-based therapies, such as photodynamic therapy (PDT). However, the utility of Porphysomes for PDT has been limited due to their poor cancer cell uptake. In this talk, I will present our discovery and development of a novel Porphysome nanoparticle to enhance their cellular uptake and PDT efficacy.
Tiffany Ho received her Bachelor of Medical Sciences degree from the University of Western Ontario and is currently pursuing her PhD in Pharmaceutical Sciences at the University of Toronto.
