Lecture II: Surface characterization and bottom up nanopatterning, part 2
10:20 am - 11:10 am
P. Weiss, UCLA
Abstract: We use molecular design, tailored syntheses, intermolecular interactions, and selective chemistry to explore the ultimate limits of miniaturization. We direct molecules into desired positions to create nanostructures, to connect functional molecules to the outside world, and to serve as test structures for measuring single or bundled molecules. Interactions within and between molecules can be designed, directed, measured, understood, and exploited at unprecedented scales. Such interactions can be used to form precise molecular assemblies, nanostructures, and patterns, and to control and to stabilize function. We selectively test hypothesized mechanisms of function by varying molecular design, chemical environment, and measurement conditions to enable or to disable function and control using predictive and testable means. Critical to understanding these variations has been developing the means to make tens to hundreds of thousands of independent single-molecule/assembly measurements in order to develop sufficiently significant statistical distributions, while retaining the heterogeneity intrinsic in the measurements. We use a number of excitation mechanisms to induce changes in the molecules and assemblies, including electric field, light, electrochemical potential, ion binding, and chemistry. We measure the electronic coupling of the contacts between the molecules and substrates by measuring the polarizabilities of the connected functional molecules. We have likewise developed and applied the means to map buried chemical functionality and interactions. The next steps are to learn to assemble and to operate molecules together, both cooperatively and hierarchically, in analogy to biological muscles. We discuss our initial efforts in this area, in which we find both interferences and cooperativity.

Lecture III: Luminescent Nanoparticles for Biomedical Applications
11:40 am - 12:30 pm
F. Vetrone, INRS
Abstract: Luminescent inorganic nanoparticles, particularly those stimulated with near-infrared (NIR) light,have been explored for a plethora of biological and medical applications. The biggest impact of such materials would be in the field of disease diagnostics and therapeutics, now commonly referred to as theranostics. Here, we will focus on NIR perturbable nanoparticles since excitation in the optically transparent “biological windows” mitigates some of the drawbacks associated with high-energy light (UV or blue) excitation, for example, little to no background autofluorescence from the specimen under investigation as well as no incurred photodamage. Moreover, one of the biggest limitations is of course, that of penetration. As such, NIR light can penetrate tissues much better than high-energy light especially when these wavelengths lie within the three biological windows. Thus, significant strides have been made in the synthesis of inorganic nanomaterials whose excitation as well as emission bands lie within one of these three optically transparent biological windows.
We present the synthesis of various NIR excited (and emitting) inorganic core/shell nanostructures and demonstrate their potential use in various biomedical applications. Furthermore, we will show how such nanoparticles can be used as building blocks towards developing multifunctional nanoplatforms for simultaneous detection and therapy of disease.
Lecture IV: Flexible, stretchable and healable electronics
2:00 pm - 2:50 pm
F. Cicoira, Polytechnique Montréal
Abstract: Organic electronics, based on semiconducting and conducting polymers, have been extensively investigated in the past two decades and have found commercial applications in lighting panels, smartphone screens, and TV screens using OLEDs (organic light emitting diodes) technology. Many other applications are foreseen to reach the commercial maturity in future in areas such as transistors, sensors and photovoltaics.
Organic electronic devices, apart from consumer applications, are paving the path for key applications at the interface between electronics and biology, such as in polymer electrodes for recording and stimulating neural activity in neurological diseases. In such applications, organic polymers are very attractive candidates due to their distinct property of mixed conduction: the ability to transport both electron/holes and ionic species. Additionally, conducting polymers offer the possibility to tune their surface properties (e.g., wettability or chemical reactivity) by changing their oxidation state, thus promoting or hindering the adhesion of biomolecules. This feature can be particularly useful for enhancing the biocompatibility of implantable electrodes.
My lecture will deal with processing and characterization of conducting polymer films and devices for flexible, stretchable and healable electronics. I will particularly focus on micro-patterning of conducting polymer films for flexible and stretchable devices and on grafting of biological species on conducting polymer surfaces.

Lecture V: Raman Spectroscopy of 2D Materials: Fundamentals
2:50 pm - 3:40 pm
S. Francoeur, Polytechnique Montreal
Raman spectroscopy is finding an exceptionally wide range of applications in both pure and applied science and its contributions to the fields of chemistry, physics and material science has made this optical spectroscopy technique one of the most important characterization techniques for the development of new materials. This is particularly true for 2D materials like graphene and black phosphorus, where Raman spectroscopy has played a critical role in their development.
In addition to providing vibrational energies and revealing electron-phonon interactions, Raman spectroscopy can determine the symmetry and atomic structure, measure the sample thickness with monolayer resolution, identify the presence of defects and disorder, evaluate the charge doping, and measure strain induced by the environment. Through its coupling with nearby electronic states, resonant Raman spectroscopy also provides critical information on the electronic band structure.
Fundamentals : In this first part, I will develop the physical concepts related to Raman scattering and its connection to the phonon band structure and electronic band structure. The classical and quantum theory of Raman scattering will be presented; the first provides useful insights and the second rigorously express the intricate connection between electronic and vibrational states.
Lecture VI: Biomedical Micro/Nanodevice Based Imaging Systems
4:10 pm - 5:00 pm
John T. W. Yeow, University of Waterloo
Abstract:The emergence of minimally invasive diagnostics and therapeutics in modern high-tech medicine has generated an unmet demand in miniaturized biomedical devices. There exist a definite need for clinical diagnostic and treatment instruments that are based on micro and nanotechnologies. In the past decade, micromachining technology and nanomaterials are making big impacts in many fields, especially in the field of biomedical engineering. The small size and low mass provided by micro/nanodevices make medical instruments portable, power efficient, and, in many cases, more effective. This talk will focus on the current development of the state-of-the-art miniaturized X-ray CT machines, and MEMS-based imaging devices.
