Magnetic nano-particles are used in medicine both as medical means, and for the transport of medicines in the pathological area of an organism. Simultaneous influence on these particles of ultrasonic radiation and a constant magnetic field allows summarising a magnetic field of an nano-particles ensemble to the value, sufficient for its registration by the remote magnetic detector. The parity connecting the measured magnetic flux of the nanoparticles with parameters of the particles, ultrasound, and the measuring system using as the magnetic detector superconducting quantum magnetometer is received. Calculations have shown, that such a system can measure a concentration of the nano-particles in colloidal solution, modeling the biological medium, in the unattainable earlier dynamic range of values (from 1 vol % to 10−7 vol %).

使用超导量子磁力计测量生物介质中磁性纳米粒子的浓度

磁性纳米粒子在医学中既用作医疗手段，又用于在生物体的病理区域中运输药物。超声波辐射和恒定磁场对这些粒子的同时影响允许将纳米粒子集合的磁场总结为足以通过远程磁检测器进行登记的值。接收将测量的纳米粒子的磁通量与粒子、超声波和用作磁探测器的测量系统的参数连接的奇偶超导量子磁力计。计算表明，这样的系统可以测量胶体溶液中纳米粒子的浓度，模拟生物介质，在早期无法达到的动态值范围内（从 1 vol % 到 10-7 vol %）。
