本文报道了双光子光聚合（TPP）制造的磁性微涡轮机具有高的表面光滑度的微流体混合。作为磁性光致抗蚀剂的关键组分，Fe（3）O（4）纳米颗粒被仔细筛选以均匀掺杂。在本工作中，油酸稳定的Fe（3）O（4）纳米粒子通过高温诱导有机相分解的铁前体的合成显示出明显的优势，在颗粒形态。将磁性纳米粒子用交联剂PO（3）-TMPTA改性后，均匀掺杂到丙烯酸酯基光刻胶中，制备了磁性纳米粒子TPP微结构。最后，成功地制作了一个磁微型涡轮机作为主动混合装置的远程控制的微流体混合。高质量磁性光刻胶的发展将导致高性能的磁可控微器件的芯片实验室（lab-on-a-chip）的应用。
Reported in this paper is two-photon photopolymerization (TPP) fabrication of magnetic microturbines with high surface smoothness towards microfluids mixing. As the key component of the magnetic photoresist, Fe(3)O(4) nanoparticles were carefully screened for homogeneous doping. In this work, oleic acid stabilized Fe(3)O(4) nanoparticles synthesized via high-temperature induced organic phase decomposition of an iron precursor show evident advantages in particle morphology. After modification with propoxylated trimethylolpropane triacrylate (PO(3)-TMPTA, a kind of cross-linker), the magnetic nanoparticles were homogeneously doped in acrylate-based photoresist for TPP fabrication of microstructures. Finally, a magnetic microturbine was successfully fabricated as an active mixing device for remote control of microfluids blending. The development of high quality magnetic photoresists would lead to high performance magnetically controllable microdevices for lab-on-a-chip (LOC) applications.
