项目摘要

Continuous monitoring of biological and chemical markers within the human body represents a significant advancement in medical technology, offering comprehensive insights into an individual’s health status. The development of such monitoring capabilities is crucial for medical professionals managing patients with compromised immune systems—a condition responsible for a substantial number of fatalities in U.S. hospitals annually and one of the costliest to diagnose and manage. The ability to access patient immune status rapidly and frequently poses a challenge for doctors seeking to make informed clinical decisions, a reality underscored by the recent COVID-19 pandemic. The research project aims to develop a novel bio-monitoring technology that enables clinicians to directly assess the immune functions of patients at point of care. This will be accomplished by integrating nanomaterials and biomolecules into a novel diagnostic device. Beyond its medical applications, this biosensing technology has potential utility in environmental monitoring, water quality assessment, and the oversight of pharmaceutical production. Additionally, this project will explore the application of bio-monitoring technology to investigate the emotional responses during learning in students from diverse educational backgrounds. In the education study, the project will produce new learning resources, broaden research opportunities for students, and offer tailored research training programs to high school and college students in the STEM education pipeline. Understanding the rules of human immunology requires continuous access to immune system status, which can provide dynamic insights about immune functions in health and disease. Critical gaps exist in our knowledge of the underlying mechanisms that drive immune dysfunction, and we lack tools that can continuously monitor immune responses. There is a critical need for novel biosensing technologies that enable continuous immunologic monitoring, timely disease trajectory prediction, and tailored medical intervention. The overall goal of this project is to develop a novel Photothermal Recycling (PTR) biosensing technology that meets the bioanalytical needs of frequent, in-line immunomodulator monitoring. A major technical challenge in biochemical monitoring is achieving fast sensor response while maintaining high sensitivity and specificity. This project plans to overcome this challenge by leveraging photothermal properties of nanomaterials to rapidly recycle binding reagents. The approach encompasses three objectives. First, an ultra-sensitive PTR assay mechanism and characterize assay performance will be demonstrated. Second, a high-throughput screening pipeline for assay generalization will be developed. Third, a prototype device for automated in-line immunomodulator analysis will be developed. The research is innovative and significant because it gives researchers a new tool to access time-resolved physiological data, which is an important resource for advancing our knowledge in understanding the rules of life. Building on the nanosensor research, the education activities will investigate the interrelation of students’ test anxiety and learning outcomes using time-resolved physiological data enabled by multimodal biosensing.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.
对人体内生物和化学标志物的持续监测代表着医疗技术的重大进步,提供了对个人健康状况的全面洞察。这种监测能力的发展对于医疗专业人员管理免疫系统受损的患者至关重要-这种疾病每年导致美国医院大量死亡,也是诊断和管理成本最高的疾病之一。快速且频繁地获取患者免疫状态的能力,对寻求做出明智临床决策的医生构成了挑战,最近的新冠肺炎疫情突显了这一现实。该研究项目旨在开发一种新的生物监测技术,使临床医生能够在护理点直接评估患者的免疫功能。这将通过将纳米材料和生物分子集成到一种新的诊断设备中来实现。除了医学应用之外,这种生物传感技术在环境监测、水质评估和药品生产监督方面也具有潜在的实用价值。此外,本项目将探索生物监测技术的应用,以调查不同教育背景的学生在学习过程中的情绪反应。在教育研究方面,该项目将产生新的学习资源,拓宽学生的研究机会,并在STEM教育管道中为高中生和大学生提供量身定制的研究培训计划。了解人类免疫学的规则需要持续了解免疫系统的状态,这可以提供关于健康和疾病中的免疫功能的动态见解。我们对导致免疫功能障碍的潜在机制的了解存在严重差距,我们缺乏能够持续监测免疫反应的工具。迫切需要新的生物传感技术来实现持续的免疫学监测、及时的疾病轨迹预测和量身定做的医疗干预。该项目的总体目标是开发一种新的光热回收(PTR)生物传感技术,以满足频繁的在线免疫调节剂监测的生物分析需求。生化监测中的一个主要技术挑战是在保持高灵敏度和高特异性的同时实现快速的传感器响应。该项目计划通过利用纳米材料的光热特性来快速回收结合试剂来克服这一挑战。该方法包括三个目标。首先,将演示一种超灵敏的PTR检测机制和表征检测性能。其次,将开发一条用于分析推广的高通量筛选管道。第三,将开发用于自动在线免疫调节剂分析的原型设备。这项研究具有创新性和重要意义,因为它为研究人员提供了一种新的工具来访问时间分辨的生理数据,这是促进我们理解生命规律的知识的重要资源。在纳米传感器研究的基础上,教育活动将使用多模式生物传感实现的时间分辨生理数据来调查学生考试焦虑和学习结果的相互关系。该奖项反映了NSF的法定使命,并通过使用基金会的智力优势和更广泛的影响审查标准进行评估,被认为值得支持。
