可调电阻脉冲传感纳米颗粒分析仪
Based on the Coulter principle, tunable resistive pulse sensing measures each particle as it passes a stretchable pore, giving sizing from 40 nm to 10 µm without optical assumptions. Only 35–100 µL is needed, and concentration spans 10⁵–10¹¹ particles/mL. Pressure is programmable to 2 kPa and voltage to 1.5 V. Size resolution is ≤ 10%.
