The Radisic, Santerre, Sefton and Shoichet groups have come together to address critical issues in biomaterials design and protein release. Together, we propose to design, synthesize and characterize innovative materials for their rheological properties – gelation time, modulus, viscous properties – all of which are critical to their use in advanced research and translation to practical application. Moreover, in order to influence cell fate, these materials often incorporate proteins into their design. By controlling the release of proteins with innovative affinity strategies, we can further influence cell growth and differentiation. This proposal sits at the interface of engineering, chemistry and biology. ******We propose to purchase two critical, inter-related instruments required for cutting edge research: an FPLC for protein purification and characterization; and a rheometer for material characterization. These instruments are critical to the advanced research of our 65+ HQP and our national and international collaborators. Moreover, the instruments will be available to the 400+ HQP in the Donnelly Centre where they will be housed. ******We are internationally renowned for advanced research in biomaterials design, protein and cell delivery. The Radisic lab investigates UV-crosslinked polymers for organ-on-a chip applications; the Santerre lab synthesizes polymers to influence the immune system; the Sefton lab designs polymers to promote new blood vessels; the Shoichet lab invents hydrogels for in situ gelation and protein affinity release. Our four laboratories are intimately linked through the Institute of Biomaterials & Biomedical Engineering – a leader in interdisciplinary research – and have links to the research institutes across the U of T ecosystem, Canada and the world. ******The DHR-2 rheometer is critical to analysis of our innovative polymers where mechanical properties, such as gelation, viscosity, shear storage and loss moduli, are essential to their design, reproducibility and ultimate utility. TA instruments is a leading manufacturer of rheometers and the DHR-2 is superb because it uses magnetic bearings, which reduce friction.******The FPLC is a key instrument in all protein synthesis, modification and release laboratories, providing well-characterized and pure proteins. The Bio-Rad NGC Quest 10 FPLC is particularly compelling because it has a Peltier-controlled cooling kit that ensures that collected proteins remain bioactive during collection and subsequent storage.******These instruments are critical to the advancement of knowledge in recognized areas of strength for Canada and the innovation economy. Undergraduates, graduate students, and post-doctoral fellows will be trained on this cutting-edge equipment, preparing them for advanced research careers in industry, academia and government, ultimately benefitting Canada, as already reflected with 6+ current spin-off companies from the laboratories of the PIs in this proposal.**

radiic, Santerre， Sefton和Shoichet团队聚集在一起解决生物材料设计和蛋白质释放的关键问题。我们建议设计，合成和表征创新材料的流变特性-凝胶时间，模量，粘性特性-所有这些都是在先进研究和转化为实际应用的关键。此外，为了影响细胞的命运，这些材料通常在其设计中加入蛋白质。通过创新的亲和力策略控制蛋白质的释放，我们可以进一步影响细胞的生长和分化。这个建议是工程学、化学和生物学的结合。******我们建议购买两种关键的，相互关联的仪器，用于前沿研究：用于蛋白质纯化和表征的FPLC；以及用于材料表征的流变仪。这些仪器对于我们的65+ HQP以及我们的国内和国际合作者的高级研究至关重要。此外，这些仪器将在唐纳利中心提供给400多名HQP，他们将被安置在那里。******我们在生物材料设计、蛋白质和细胞传递方面的先进研究享誉国际。radiic实验室研究紫外交联聚合物在器官芯片上的应用；Santerre实验室合成聚合物来影响免疫系统；塞夫顿实验室设计聚合物来促进新血管的形成；Shoichet实验室发明了用于原位凝胶和蛋白质亲和力释放的水凝胶。我们的四个实验室通过生物材料与生物医学工程研究所（跨学科研究的领导者）紧密联系在一起，并与多伦多大学生态系统、加拿大和世界各地的研究机构建立了联系。****** DHR-2流变仪对于分析我们的创新聚合物至关重要，其中机械性能，如凝胶，粘度，剪切储存和损失模量，对其设计，可重复性和最终实用性至关重要。TA仪器是流变仪的领先制造商，DHR-2是一流的，因为它使用磁性轴承，减少摩擦。****** FPLC是所有蛋白质合成，修饰和释放实验室的关键仪器，提供表征良好的纯蛋白质。Bio-Rad NGC Quest 10 FPLC特别引人注目，因为它有一个peltier控制的冷却套件，确保收集的蛋白质在收集和随后的储存过程中保持生物活性。******这些工具对于加拿大和创新经济在公认的优势领域的知识进步至关重要。本科生、研究生和博士后研究员将接受这种尖端设备的培训，为他们在工业、学术界和政府部门从事高级研究工作做好准备，最终使加拿大受益，正如本提案中从pi实验室衍生出来的6多家公司所反映的那样。**
