文摘

White blood cell quantization was achieved with large range and high accuracy. Paper-based label-free electrochemical method was proposed. Sensing mechanism relied on diffusion blockage by trapped cells. Differential pulse voltammetry was proved suitable for paper porous electrode. Sensing system was integrated with smartphone using wireless communication.
