Multistep Continuous‐Flow Microsynthesis of Magnetic and Fluorescent γ‐Fe2O3@SiO2 Core/Shell Nanoparticles

Coupled microreactors allow fast, continuous, multistep synthesis of the title compound. Thus, grafting with APTES is carried out in microreactor I, mixing with sol–gel TEOS and APTES labeled with Rhodamine B isothiocyanate (RITC) in II, and coating in III. This technique opens the way to developing a lab-on-a-chip platform for nanoparticle synthesis.
