This subproject is one of many research subprojects utilizing the resources provided by a Center grant funded by NIH/NCRR. The subproject and investigator (PI) may have received primary funding from another NIH source, and thus could be represented in other CRISP entries. The institution listed is for the Center, which is not necessarily the institution for the investigator. ABSTRACT: Currently, microfluidics technology is being applied to develop micromixers for time resolved cryo-electron microscopy (TRCEM) application. TRCEM requires fast and homogeneous premixing of tiny amounts of macromolecules in the time scale of milliseconds or less. Work is also just beginning in which this technology will be applied to the problems of specimen deposition onto EM grids and rapid freezing. Our goal for the remainder of this grant is to design and test a microfluidics-based device that allows TRCEM experiments to be conducted routinely with millisecond time resolution and requires only the small amounts of biomolecules that are often available to researchers.

这个子项目是许多研究子项目中的一个 由NIH/NCRR资助的中心赠款提供的资源。子项目和 研究者（PI）可能从另一个NIH来源获得了主要资金， 因此可以在其他CRISP条目中表示。所列机构为 研究中心，而研究中心不一定是研究者所在的机构。 摘要： 目前，微流体技术正被应用于开发用于时间分辨低温电子显微镜（TRCEM）应用的微混合器。 TRCEM需要在毫秒或更短的时间内快速均匀地预混合微量的大分子。这项技术将应用于EM网格上的样品沉积和快速冷冻问题的工作也刚刚开始。 我们的目标是设计和测试一种基于微流体的设备，使TRCEM实验能够以毫秒级的时间分辨率常规进行，并且只需要研究人员经常使用的少量生物分子。
