This proposal is to develop an instrument that can rapidly identify drug resistant cancer cells in tumors and prescribe a course of treatment for the patient that minimizes chance of cancer recurrence. Drug resistance is one of the greatest impediments to treating both cancer and infectious disease and has been identified as one of the greatest public health threats of the next several decades. The proposed miniaturized instrument can be utilized for rapidly screening cancer patients for drug resistance and identifying the key molecular players involved and selecting optimal cancer treatment drugs. In this work, a microfluidics/electronic/data-driven crosscut approach is proposed to enable a rapid technology that can identify drug resistant cells using machine learning and examine the key protein pathways resulting in resistance using a label-free sensing array. The proposed platform is adaptive and reconfigures itself to assay the relevant proteins on-demand and avoids a resource-hungry brute force approach. This interdisciplinary project will engage and train both graduate and undergraduate students in various areas. The PI will also engage K-12 students through outreach workshops, local industry through educational lectures, and the general public through development of an online course, resulting in broad dissemination of knowledge. A new class of data-driven biosensors will be developed that can adapt themselves on-demand to detect and treat multidrug resistant cancers. Treatment of multi-drug resistance in cancer is difficult using static analysis platforms because of the rapid ability of tumor sub-clones to mutate and become insusceptible to a chemotherapeutic drug, thus an adaptive approach can be more efficient. An all-electronic platform will be developed for rapidly sorting drug resistant cells and adaptively analyzing the molecular pathways involved in resistance using a reconfigurable array of sensors. The analyzer will iteratively detect drug resistant cells using reconfigurable impedance cytometry in conjunction with machine learning, then sort them using dielectrophoresis (DEP), analyze them using a reconfigurable array of label-free protein sensors, and then use a machine learning classifier to further sub-type the drug resistant cells to select a drug combination to test in the subsequent iteration. An integrated closed-loop feedback system will be fabricated and characterized for sorting drug-sensitive and drug-resistant cells, and analyze differential expression of potential drug-resistance pathways iteratively against key drug candidates. The result of this research will be a new class of data-driven biosensors that can detect and sub-type drug resistant cancer cells from a breast tumor tissue that can be broadly applied to a multitude of biomedical applications including anti-microbial resistance.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.

该提案旨在开发一种仪器，可以快速识别肿瘤中的耐药癌细胞，并为患者提供治疗过程，最大限度地减少癌症复发的机会。耐药性是治疗癌症和传染病的最大障碍之一，已被确定为未来几十年最大的公共卫生威胁之一。所提出的小型化仪器可用于快速筛查癌症患者的耐药性，并确定所涉及的关键分子参与者和选择最佳的癌症治疗药物。在这项工作中，提出了一种微流体/电子/数据驱动的横切方法，以实现一种快速技术，该技术可以使用机器学习识别耐药细胞，并使用无标记传感阵列检查导致耐药性的关键蛋白质途径。拟议的平台具有自适应性，可自行重新配置以按需检测相关蛋白质，并避免了消耗资源的强力方法。这个跨学科的项目将从事和培训研究生和本科生在各个领域。PI还将通过外联讲习班吸引K-12学生，通过教育讲座吸引当地行业，通过开发在线课程吸引公众，从而广泛传播知识。将开发一类新的数据驱动生物传感器，可以根据需要进行调整，以检测和治疗多药耐药癌症。使用静态分析平台治疗癌症中的多药耐药性是困难的，因为肿瘤亚克隆快速突变并变得对化疗药物不敏感的能力，因此自适应方法可能更有效。将开发一个全电子平台，用于快速分选耐药细胞，并使用可重新配置的传感器阵列自适应地分析与耐药性有关的分子途径。该分析仪将使用可重构阻抗细胞仪结合机器学习迭代检测耐药细胞，然后使用介电泳（DEP）对其进行分类，使用可重构的无标记蛋白传感器阵列对其进行分析，然后使用机器学习分类器进一步对耐药细胞进行分型，以选择药物组合在后续迭代中进行测试。一个集成的闭环反馈系统将被制造和表征，用于分选药物敏感和耐药细胞，并针对关键候选药物反复分析潜在耐药途径的差异表达。 这项研究的成果将是一类新的数据驱动的生物传感器，可以检测和亚型耐药癌细胞从乳腺肿瘤组织，可广泛应用于多种生物医学应用，包括抗菌药物耐药性。该奖项反映了NSF的法定使命，并已被认为是值得支持的评估使用基金会的智力价值和更广泛的影响审查标准。
