【摘要】：目的:設(shè)計(jì)基于磁阻傳感器的檢測(cè)系統(tǒng),實(shí)現(xiàn)實(shí)時(shí)磁靶向藥物運(yùn)動(dòng)軌跡的跟蹤。方法:用Fe-Fe3O4核殼結(jié)構(gòu)納米顆粒模擬磁靶向藥物,磁阻傳感器檢測(cè)到其磁場(chǎng)信號(hào)進(jìn)行處理和變換,得到其空間位置信息。結(jié)果:用LabVIEW軟件實(shí)現(xiàn)實(shí)時(shí)檢測(cè),實(shí)時(shí)顯示磁性顆粒運(yùn)動(dòng)位置。結(jié)論:檢測(cè)系統(tǒng)具有良好的實(shí)時(shí)性及精準(zhǔn)度,可為臨床研究磁靶向藥物的在體檢測(cè)提供一種新方式。
[Abstract]:Aim: to design a detection system based on magnetoresistive sensor to track the moving track of real-time magnetically targeted drugs. Methods: the Fe-Fe3O4 core-shell structure nanoparticles were used to simulate the magnetically targeted drugs, and the magnetic field signals detected by the magnetoresistive sensors were processed and transformed. Results: the real time detection of magnetic particles was realized by LabVIEW software, and the moving position of magnetic particles was displayed in real time. Conclusion: the detection system has good real time and accuracy. It may provide a new method for in vivo detection of magnetic target drugs.
