The utilization of Mightex LED systems for the generation of polymeric microstructures

具有明确形状和尺寸的微小聚合物结构，如颗粒、膜和图案化表面，在生物医学应用中具有巨大的潜力，如侵入性药物递送、生物测定、生物传感和细胞研究。一种流行的方法来产生这种结构是使用 ** 光聚合与紫外光。金属卤化物灯通常用于紫外线光源，但 ** 受到紫外线强度波动，长预热要求和短寿命的影响。另外，LED** 系统提供高度稳定的强度，不需要预热或冷却，寿命长，但它们 ** 主要用于生命科学研究中的目标模拟和成像，但在材料科学中也有潜在的应用 **，例如，基于光聚合来创建聚合物结构。瑞尔森大学的黄博士的研究小组已经开发了几种基于光聚合的聚合物结构技术。Mightex Systems是光子产品和服务的领先制造商和供应商。其主要产品之一是大功率LED系统。该Engage赠款将使Migthex**Systems和瑞尔森团队能够开始致力于成功地将LED系统用于材料科学中的应用 **，特别是生成具有明确形状和尺寸的颗粒和膜。因此，** 此次合作将扩大Mightex LED系统的使用范围，从而加强其市场份额。

Tiny polymeric structures with well-defined shape and size such as particles, membranes, and patterned**surfaces can have great potential in biomedical applications such as invasive drug delivery, bioassay,**biosensing, and cellular studies. One popular approach to generate such structures is to use**photopolymerization with ultraviolet light. The Metal Halide Lamps are commonly used for a UV source but**suffer from UV-intensity fluctuation, long warm-up requirement, and short-life-time. Alternatively, LED**systems offer highly stable intensity, no requirements for warm-up or cool-downt, and long life-time but they**are mostly used for targeted simulation and imaging in life science research, yet there are potential applications**in material science, for example, to create polymeric structures based on photopolymerization.**Dr. Hwang's group at Ryerson University has developed several techniques to generate polymeric structures**based on photopolymerization. Mightex Systems is a leading manufacturer and supplier of photonic products**and services. One of their main products is high-power LED systems. This Engage grant will enable Migthex**Systems and the Ryerson team to begin working towards successfully using LED systems for their application**in material science, particularly to generate particles and membranes with well-defined shape and size. Thus,**this collaboration will broaden the utilization of Mightex LED systems and thus strengthen their market share.
