    摘要:

    细胞的形态学和电生理学特征是生命科学研究的重点,然而传统的单模态探测系统因只能测量单一参数,难以全面揭示细胞复杂的生理反应。多模态探测技术因其同时检测多种参数的能力逐渐受到重视,但现有系统在多模态、大视场和高分辨率之间面临权衡难题,且难以实现实时探测。为解决这些问题,开发了一种新型的成像电学双模态监测技术,通过创新设计的成像电学双模芯片,实现对细胞的实时成像和电学信号探测。具体技术包括通过“异质封装”整合无透镜显微成像芯片与微电极阵列的成像电学双模芯片设计,芯片视场占整个芯片面积的90%以上;集成基于现场可编程门阵列的成像控制系统以及多功能电学信号处理系统的探测系统构建。实验验证显示,该系统能够有效监测C57小鼠胎鼠皮层神经元和胶质瘤GL261细胞的共培养体系,展示了良好的实时性和综合探测能力。这项技术为细胞的综合生理监测提供了创新解决方案,有望在生命科学研究和临床应用中发挥重要作用。

    Abstract:

    The morphological and electrophysiological characteristics of cells are a key focus in life science research. However, traditional single-modal detection systems, which can only measure a single parameter, struggle to fully reveal the complex physiological responses of cells. Multi-modal detection technology, which has the capability to simultaneously measure multiple parameters, is gaining attention. Yet, existing systems face challenges in balancing multi-modality, large field of view, and high resolution, while also finding it difficult to achieve real-time detection. To address these issues, this study developed a novel dual-modal imaging and electrical monitoring technology. Through an innovatively designed imaging-electrical dual-modal chip, it enables real-time imaging and electrical signal detection of cells. The specific technology includes the design of a dual-modal imaging-electrical chip that integrates lensless microscopy imaging chips with microelectrode arrays through “heterogeneous packaging,” with the chip’s field of view covering more than 90% of the chip area. Additionally, a detection system was constructed, integrating an imaging control system based on field-programmable gate arrays and a multifunctional electrical signal processing system. Experimental validation showed that this system effectively monitors co-cultures of cortical neurons from C57 mouse embryos and glioma GL261 cells, demonstrating good real-time performance and comprehensive detection capabilities. This technology provides an innovative solution for comprehensive physiological monitoring of cells and holds promising potential for application in life science research and clinical practice.
