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.
Irene Chen is currently going into her fourth year of her Bachelor of Science in Biology and Psychology at the University of Alberta. She was an Undergraduate Research Assistant at the Wishart Lab at the University of Alberta from May 2021 to March 2022.

Application of Early Health Technology Assessments to Nanomedicine: A Review of Conceptual Frameworks
Early Health Technology Assessments (eHTA) provide a systematic approach to guide early evidence generation and demonstrate value to stakeholders We aim to summarize existing literature on existing eHTA frameworks, and to explore the applicability of these frameworks to nanomedicine.

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. Her research focuses on the development of structurally novel lipids can be used to encapsulate and deliver therapeutic nucleic acids in lipid nanoparticle form. Selective delivery of nucleic acids to target tissues is an important consideration guiding lipid design.

Gold Nanoparticles Encapsulation into Polymeric Micelles for Cancer Theranostics
The presentation will discuss the development and characterization of hydrophobically modified gold nanoparticles by using poly(e-caprolactone), followed by their encapsulation into amphiphilic block copolymers, and their potential as a new theranostic platform.
Talita de Francesco obtained her MSc in chemistry at University of Sao Paulo, and is now a PhD candidate at University of Victoria. Her research goal is to develop a theranostic platform for cancer treatment by functionalizing and encapsulating gold nanoparticles into amphiphilic block copolymers.

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.
Yifei Gu obtained her M.Sc. in biophysics with Dr. Sabrina Leslie at McGill University and now works as a research assistant in the Leslie Lab within the Michael Smith Laboratories at UBC. Her research focuses on developing tools and assays to study the drug-loading and -releasing mechanism of lipid nanoparticles (LNPs) and help improve the design of an LNP drug delivery platform.

X-Ray Triggered Drug Release of Hybrid Protein-Gold Nanoparticle
This research focuses on the use of hybrid Zein-gold nanoparticles in X-Ray triggered drug release. A proof-of-principle release study and characterization of the hybrid system shows promising results for its potential in cancers which combine high doses of chemotherapy and radiation, such as head and neck cancer.

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. Her research focuses on investigating the application of a new generation of porphysomes for photodynamic therapy and understanding the mechanism underlying their enhanced cellular uptake and efficacy.
