The broader impact/commercial potential of this I-Corps project is to improve the capabilities of sample collection in industries where this step is critical to high quality results. Currently, poor recovery efficiencies, inability to collect from diverse environments, and no standardization affects this activity. The proposed technology will improve sample collection systems for better ease of sampling, an improved range of samples that can be collected, and the quality of evidence collected for the forensic science industry, expected to be a ~$40 B industry by 2025. The solution would lead to less failed testing, improved utilization of time and resources, and improved case-solving opportunities. This I-Corps project will explore a venturi-based technology to generate a vacuum. Through a modular design, many front-end applicators can be equipped to allow one handheld device to collect a number of samples. The device is lightweight, portable, field deployable and requires no electricity. It uses a compressed air tank to power the venturi pump. This device can collect trace amounts of “touch-DNA” evidence, particulates from solid and porous surfaces, and pathogens associated with agricultural disease in infected trees. This technology will allow experts to collect more efficiently samples and enable new sample collection and testing.This award reflects NSF's statutory mission and has been deemed worthy of support through evaluation using the Foundation's intellectual merit and broader impacts review criteria.

这个I-Corps项目的更广泛的影响/商业潜力是提高行业的样本收集能力，这一步骤对高质量的结果至关重要。目前，回收效率低下、无法从不同环境中收集数据以及没有标准化影响了这项活动。拟议的技术将改善样本收集系统，以更好地方便采样，改善可以收集的样本范围，并为法医科学行业收集证据的质量，预计到2025年将成为一个约40 B美元的行业。 该解决方案将减少失败的测试，提高时间和资源的利用率，并改善解决案例的机会。这个I-Corps项目将探索一种基于Venturi的技术来产生真空。通过模块化设计，可以配备许多前端点样器，使一个手持设备可以收集许多样品。该设备重量轻，便携，可现场部署，不需要电力。它使用压缩空气罐为文丘里泵提供动力。该设备可以收集微量的“触摸DNA”证据，固体和多孔表面的颗粒，以及受感染树木中与农业疾病相关的病原体。这项技术将使专家能够更有效地收集样本，并使新的样本收集和测试。这个奖项反映了NSF的法定使命，并已被认为是值得通过使用基金会的智力价值和更广泛的影响审查标准进行评估的支持。
