Maghemite particles for spermidine separation

Abstract

We report the optimal conditions for the separation of spermidine from different types of samples, for example blood or cancer cells and its subsequent determination by ion-exchange liquid chromatography (IEC) with UV-VIS detector. Here in, we synthesized paramagnetic particles able to isolate and immobilize spermidine from blood of patients with cancer or cancer cells and thus preconcentrate it for analysis. Dowex surface was covered by nanomaghemite (-Fe2O3) or maghemite particles surface was modified by chitosan and sulfoxyethyl cellulose. The best separation properties showed Dowex microparticles. The paramagnetic particles can be used in the future for isolation of spermidine from real samples and diagnosis of cancer.
