This EAGER award by the Biomaterials program in the Division of Materials Research to University of Maryland is aimed at obtaining preliminary data on the material properties and blood coagulation mechanism of a novel polymer hemostatic hydrogel material. Structure-property material optimization experiments will be performed to determine the key chemical, biological, mechanical and morphological characteristics of the hydrogel that are necessary to induce fibrin formation and produce a robust clot. Blood Clotting Factor deficient and Blood Clotting Factor inhibition studies will be completed to isolate the vital biological components in the hemostasis. Dynamic mechanical analysis experiments will be performed to determine the various regions of mechanical equivalency in these 3-component hydrogels, and elucidate the relationship between mechanical properties, Blood Clotting FVII activation, and fibrin formation. The education activities to be undertaken in this work are designed to educate and train next-generation scientists and engineers that embrace diversity as a strength. Initiatives are planned that assist in undergraduate and graduate education, graduate student mentoring, and training of high school students from schools in minority-rich communities.Uncontrolled hemorrhaging accounts for over 1 million deaths world-wide each year and is the leading cause of preventable deaths after hospital admission for physical injury in the U.S. trauma centers. Millions more around the world suffer injuries that need bandaging to prevent blood loss and cover wounds. There is a clear need for the advancement of hemostatic technology in order to develop next generation materials which are inexpensive, safe, and capable of rapidly stopping blood loss. The proposed research will have an immediate and direct impact on the millions of people around the world who die of blood loss each year along with those who suffer from lethal clotting disorders, such as hemophilia. An inexpensive, biocompatible synthetic material that has the ability to induce effective clotting would have a transformative scientific impact and has the potential to save countless lives. Students sponsored from this project will be educated and trained in polymer material science and bioengineering. The PI will utilize the existing programs in the campus to recruit and train students of many different educational levels, and from diverse and under-privilege backgrounds.

马里兰大学材料研究部生物材料项目颁发的EAGER奖项旨在获得新型聚合物止血水凝胶材料的材料特性和凝血机制的初步数据。将进行结构性能材料优化实验，以确定水凝胶的关键化学、生物、机械和形态特征，这些特征是诱导纤维蛋白形成和产生坚固凝块所必需的。将完成凝血因子缺乏和凝血因子抑制研究，以分离止血中的重要生物成分。将进行动态力学分析实验以确定这些 3 组分水凝胶中机械等效性的各个区域，并阐明机械特性、凝血 FVII 激活和纤维蛋白形成之间的关系。这项工作中将进行的教育活动旨在教育和培训将多样性视为优势的下一代科学家和工程师。计划采取多项举措，协助本科生和研究生教育、研究生指导以及对少数民族社区学校高中生的培训。失控的出血每年导致全球超过 100 万人死亡，并且是美国创伤中心因身体受伤入院后可预防死亡的主要原因。 世界各地还有数百万人受伤，需要包扎以防止失血和覆盖伤口。显然需要进步止血技术，以开发廉价、安全且能够快速止血的下一代材料。这项拟议的研究将对世界各地每年因失血而死亡的数百万人以及患有血友病等致命凝血疾病的人产生直接和直接的影响。一种廉价的、生物相容性的合成材料，能够诱导有效的凝血，将产生变革性的科学影响，并有可能拯救无数的生命。该项目资助的学生将接受高分子材料科学和生物工程方面的教育和培训。 PI 将利用校园现有的项目来招募和培训来自不同教育水平、不同背景的学生。
