Abstract

This work presents a programmable CMOS DEP chip that allows real-time control over the spatial distribution of DEP force, enabling controlled cell movement on the chip surface, from single-cell manipulation to multi-cell patterning. Implemented on a standard 0.18 μm CMOS process without post-processing, the chip features a 128 × 128 array of individually controllable 10 μm microelectrodes with 0.28 μm spacing. Utilizing Metal 5 electrodes in a 1P6M process, the chip achieves particle manipulation speeds up to 27 μm/s while operating at only 1.8 V, preserving cell viability as confirmed through post- DEP assessments. The implementation of time-sharing patterns enhances manipulation precision by creating distinct boundaries between phases. Experiments demonstrate the chip's capabilities in particle patterning, concentration control, and single-particle manipulation, all performed sequentially on the same chip. Additionally, stem cell aggregation control demonstration offers possibilities for future differentiation studies. With its reconfigurability, this DEP chip offers promising solutions to technical challenges in cell preparation, drug screening, and other biological applications.

用于细胞操作的可编程CMOS DEP芯片。
这项工作提出了一种可编程的CMOS DEP芯片,可以实时控制DEP力的空间分布,从而可以控制芯片表面上的细胞运动,从单细胞操作到多细胞图案。该芯片采用标准的0.18 μm CMOS工艺,无需后处理,具有128 × 128的独立可控10 μm微电极阵列,间距为0.28 μm。该芯片在1P6M工艺中使用Metal 5电极,在仅1.8 V的电压下实现了高达27 μm/s的粒子操作速度,并通过DEP后评估确认了电池活力。分时模式的实现通过在阶段之间创建明确的边界来提高操作精度。实验证明了该芯片在粒子模式、浓度控制和单粒子操作方面的能力,所有这些都在同一芯片上依次进行。此外,干细胞聚集控制的论证为未来的分化研究提供了可能。由于其可重构性,这种DEP芯片为细胞制备、药物筛选和其他生物应用中的技术挑战提供了有希望的解决方案。
