Formasi nanopartikel besi oksida (IONP) melalui kaedah perhentian aliran pantas dijalankan
menggunakan RX2000 Rapid Mixing Unit. IONP multiteras telah distabilkan menggunakan
polimer PSS 70k dengan pelbagai kepekatan IONP dari 10ppm hingga 50ppm. Dengan masa yang
ditetapkan pada satu minit, kinetik penjerapan telah diperolehi. Keputusal kinetik penjerapan tidak
stabil dan bising, dan membawa kepada kesimpulan bahawa penyalutan polimer pada IONP tidak
berlaku. Oleh sebab sifat IONP untuk menggumpal and memendap, kluster telah terbentuk
sebelum kerja eksperimen bermula, dan telah mewakili gerakan penyebaran, bukannya kinetik
penjerapan yang dikehendaki. Dengan ini, dapat disimpulkan bahawa kaedah perhentian aliran
pantas tidak boleh menghasilkan multiteras zarah nano besi oksida.

The rapid stopped-flow assembly of multicore iron oxide nanoparticle (IONP) was performed
using the RX2000 Rapid Mixing Unit. IONP was to be stabilized using polymer PSS
(Poly(sodium(4)styrenesulfonate)70k with varying concentrations of IONP from 10ppm to
50ppm. With a fixed time of one minute, the adsorption kinetics were obtained. Adsorption kinetic
results were unstable and noisy, leading to conclusions that ineffective coating has taken place.
Due to the nature of IONP to agglomerate and sedimentate, clusters were formed even before
experimental work began, hence leading to kinetics representing the diffusion motion, rather than
the adsorption kinetics that is intended. It was concluded that rapid stopped-flow method was not
feasible to form multicore iron oxide nanoparticle.
