Project Summary An electrolyte panel is a blood test that measures the levels of electrolytes and carbon dioxide in your blood. Electrolytes are chemicals found naturally in the body, such as potassium, calcium, sodium, and are needed to keep the body's balance of fluids at the proper level and to maintain normal functions, such as heart rhythm, muscle contraction, and brain function. CO2 is a waste product made when the body breaks down food for energy, CO2 helps your blood stay at the right pH. Physicians may order an electrolyte panel as part of a regular health examination, to check on or diagnose a medical condition, and/or assess whether medications are negatively affecting one electrolyte levels. Electrolyte panels are currently typically carried out as laboratory test, where a blood sample is sent out to be characterized via manual ion selective electrodes (ISEs). This process takes a significant amount of time, is cost inefficient, and has issues associated with the fragility and maintenance of manual ISEs. And, while there has been the development of point-of-care or handheld electrolyte panel systems, these current systems have failed to gain widespread use or traction, due to issues with stability, storability, accuracy, and inability to be combined with other assays for comprehensive blood work analyses, i.e. complete blood count (CBC), chemistry (basic metabolic) panel, thyroid panel, nutrient tests for levels of vital nutrients, such as iron or B vitamins, enzyme markers, and STDs. Recently however, Professor Henry S. White at the University of Utah has developed a new nanopore-based ISE technology that solves the predominant issues of conventional ISEs, can be multiplexed to a high degree, can be mass fabricated and can be easily combined with other nanopore-based characterization techniques for complete blood work analyses on a single device. During this Phase 1 STTR program, Electronic BioSciences will develop and expand upon Professor White’s nanopore-based ISE technology, developing a storable, highly stable, rapid, and accurate electrolyte panel POC testing vial. The utility of this device will be demonstrated characterizing electrolyte abnormalities in blood samples from chronic kidney disease patients.

项目概要 电解质检查是一种血液测试，可测量血液中电解质和二氧化碳的水平。 电解质是体内天然存在的化学物质，例如钾、钙、钠，是维持生命所需的物质。 保持身体的液体平衡在适当的水平并维持正常的功能，例如心律， 肌肉收缩和大脑功能二氧化碳是身体分解食物时产生的废物。 能量，二氧化碳可以帮助您的血液保持在正确的 pH 值，医生可能会订购电解质板作为常规检查的一部分。 健康检查，检查或诊断健康状况，和/或评估药物是否有效 对电解质水平产生负面影响目前通常作为实验室测试进行。 血液样本被发送出去，通过手动离子选择电极 (ISE) 进行表征。 需要大量时间，成本效率低下，并且存在与脆弱性和维护相关的问题 手动 ISE 的发展，同时还开发了现场护理或手持式电解质面板。 系统，由于稳定​​性问题，这些当前系统未能获得广泛使用或牵引， 可储存性、准确性以及无法与其他全面的血液工作分析相结合，i Assay.e。 全血细胞计数 (CBC)、化学（基础代谢）检测、甲状腺检测、生命体水平营养测试 然而，亨利·S·怀特教授最近指出，铁或 B 族维生素、酶标记物和性传播疾病等营养物质 犹他大学开发了一种新的基于纳米孔的 ISE 技术，解决了主要问题 传统 ISE 的问题，可以高度复用，可以批量制造，并且可以轻松 与其他基于纳米孔的表征技术相结合，可在单个样本上进行完整的血液工作分析 在第一阶段 STTR 计划中，Electronic BioSciences 将开发和扩展教授。 White基于纳米孔的ISE技术，开发可储存、高度稳定、快速且准确的电解质 将展示该装置的实用性，以表征电解质异常。 慢性肾病患者的血液样本。
