We present a microfluidic platform that allows undergoing different chemical operations in a nanoliter droplet starting from the colloidal suspension of magnetic iron oxide (γ-Fe2O3) nanoparticles "NPs" (ferrofluid). These operations include: mixing, flocculation, magnetic decantation, colloidal redispersion, washing, surface functionalization, heating and colloidal assembly. To prove the platform capabilities, we produced fluorescent and magnetic nanoassemblies composed of fluorescent silica and magnetic NPs.
我们展示了一种微流控平台，该平台能够以纳米升液滴为起始，从磁性氧化铁（γ-Fe2O3）纳米颗粒“NPs”（铁磁流体）的胶体悬浮液开始进行不同的化学操作。这些操作包括：混合、絮凝、磁性倾析、胶体再分散、洗涤、表面功能化、加热和胶体组装。为了证明该平台的能力，我们制备了由荧光二氧化硅和磁性纳米颗粒组成的荧光和磁性纳米组件。
