Grant: Research Tools and Instruments

Advanced nano-fabrication technologies enable the research team to pursue inter-disciplinary researches in biomaterials and regenerative medicine, novel bio-adhesive, fuel cell and sensor development. Robust characterization of the nano-structure are vital for the research program. High resolution and efficient 3D imaging of large area samples will be needed in each of the research areas. Currently, at the University of Waterloo (UW), the team rely on conventional surface characterization methods such as scanning electronic microscopy (SEM) or atomic force microscopy (AFM), which require slow, manual measurement on small area, while sample preparation and contacting mode measurement will induce surface damages. These cause long delay in research and training, requiring additional research funding and manpower, and limiting the potential and return-on-investment of valuable engineering programs at UW. We propose the acquisition of a non-contact laser microscope with automated surface roughness analysis. The superiorities of the non-contact laser microscope include fast high-resolution image acquisition, motorized stage with auto-focusing and tile imaging for 3D characterization of large non-planar specimens. Non-contact measurement will eliminate surface damage and possibilities of artifacts. With a dual confocal system and multilayer mode, the non-contact laser microscope enables the analysis of multiple layers, which is essential to examine cell morphology on nano-structure. The system will be used to characterize a wide range of materials from prototypes of nano-structures on biomaterials, porous membrane for fuel cells, biosensors and biomedical devices that may be licensed and commercialized in the future. Thus, the non-contact laser microscope provide a versatile and high-throughput characterization that is needed by the research programs, and it can enable building of new research program and engaging broader research partners. The requested equipment will be the first motorized industrial surface roughness microscope at UW and in Kitchener-Waterloo area. The team comprises of experts in nanotechnology for electrical, energy and biological applications. The efficient non-contact laser microscope will enable the team to accelerate the application of nanotechnology at UW, maintaining UWs leadership in this field. In addition to enabling collaboration with industrial partners, at least 65 students from the 6 research teams will benefit from access to the surface characterization system each year to further advance their education and training in engineering and nanofabrication technologies. Trainees will learn specialized surface characterization on different types of materials, as well as the application of the nanostructured devices, that will equip them for the fast-growing nanotechnology-based biomedical, electrical industries.
