Nanoparticle Shape Effects on Nano-Bio Interactions

Anisotropic gold nanoparticles exhibit shape-dependent properties beneficial for drug delivery vehicles, imaging probes, and therapeutic agents. Although increased therapeutic efficacy has been realized, direct visualization of how engineered nanoparticles interact with specific organelles or cellular components has been limited. Such interactions will have implications for fundamentals in cancer biology as well as in the design of translational nanoconstructs. This talk will describe how drug-loaded gold nanostars can behave as optical probes to interrogate how targeting nanoconstructs interact with cells at the nanoscale. We will focus on model cancer cell systems that can be used to visualize how gold nanoconstructs target cells, rotate, and translate on the plasma membrane and are endocytosed and trafficked intracellularly. Differences in single-particle dynamics reveals how nanoparticle geometry affects binding to cell-membrane receptors and internalization. That nanoparticle shape can preserve ligand activity of nanoconstructs extracellularly as well as dictate spatial organization intracellularly will have important implications for engineering designer nanoconstructs for nanomedicine.

Small Science and Big Science Entanglement: The Advent of a New Era of Synchrotron Light Sources for Chemical Research

The matured third generation synchrotron light sources have provided an exciting playground and unprecedented opportunities for chemical research. The very bright, energy-tunable, highly collimated, and pulsed light sources are making tunable X-rays readily available for all branches of science and technology: from proteins to drug delivery, from CO2 capture to environmental protection, from energy materials to energy storage and conversion, from cultural heritage materials to preservation and conservation, and from soil science to agricultural advancement, just to name a few.

In this talk, I will describe the powerful synchrotron technology and its applications. More importantly, I will present how synchrotron technology came about, especially in the Canadian context and how the science community can benefit from this powerful tool for research. The impact of synchrotron on the sociology of science will also be noted. The world is now marching toward the fourth-generation synchrotron technology which includes diffraction limited-electron storage ring and free-electron laser. The Canadian synchrotron community is in pursue of the next generation synchrotron and will engage the scientific community and industry moving forward.

Towards a Panacea in Chemical Sensing

The development of devices to facilitate the chemical determination of organic compounds in complex matrices has largely consisted of two main directions. One is the design of sensors, which are simple, portable devices that enable good performance for the on-site analysis of real samples, even in-vivo.  However, sensors are typically limited to single-component determination, with selectivity determined by membrane and/or readout characteristics. The second direction entails the use of hyphenated separation using mass spectrometry technologies, such as GC/MS and LC/MS. Indeed, the rapid development of mass spectrometry and multidimensional approaches in recent years has enabled multicomponent determination and the comprehensive characterization of the composition of complex samples. The main limitation of this direction is the demands required to prepare complex samples in a manner that enables good analytical performance. Miniaturized, on-site versions of the instruments used in this stream are already available or being constructed, so issues related to size and portability are currently being addressed; however, what are missing are effective sampling/sample-preparation tools.

To address the above challenges, we propose combining sensor a design strategy, thus providing good isolation selectivity, and chromatography/spectrometry technologies, which facilitate multicomponent characterization with high accuracy, reproducibility, and precision. For this approach to be effective, the “sensor” must be able to accumulate enough analyte during sampling to facilitate sensitive determinations. To accomplish this task, we have been designing matrix-compatible high-analyte-capacity probes with flexible shapes and morphologies that facilitate GC/MS, LC/MS, or direct mass spectrometry readout. These probes consist of thin, matrix-compatible coatings consisting of extraction phases made up of sorbent particles and a binder, which forms a protective layer that prevents direct contact with the matrix particles while also facilitating the analytes’ adhesion to the support. The designed probes enable non-exhaustive sampling in manner similar to sensors, but much longer extraction times are used to allow the accumulation of sufficient quantities of analytes to allow sensitive detection. Such chemical biopsy probes selectively enrich smaller molecules, which can diffuse though the protective layer formed by the binder while leaving the investigated system intact, thus preventing macromolecules in the sample from influencing the measurement quality. After completing the sampling/sample-preparation step, the probes are introduced to the analytical instrument where the analytes are isolated via thermal or solvent desorption.

This flexible solid-phase microextraction (SPME) approach has deployed for a wide range of the applications, with results demonstrating its superior performance compared to traditional approaches to the determination of complex samples [1]. In addition to better analytical performance, SPME possesses much better sustainability characteristics, as it eliminates or minimizes the use of organic solvents, making it an ideal tool for future generations of chemists. The main challenge in adopting the SPME approach is that, as with sensors, it is based on non-exhaustive sampling, whereas standard technologies utilize exhaustive approaches, with performance being evaluated based on the recovery of spiked analytes. This feature has led to some resistance to the adoption of SPME technologies by many regulatory agencies.  However, despite this challenge, SPME technology remains commonly used in many areas where no good solutions exist. Furthermore, the application of SPME in various scientific disciplines is also fueled by its “green” features.  During the talk, examples of different SPME designs that address important world challenges will be presented to help the audience gain a deeper appreciation of the impact of this chemical sensing approach.
