Abstract
Przedmiotem zgłoszenia jest sposób otrzymywania ultramałych superparamagnetycznych nanocząstek gamma-tlenku żelaza(III) (USPIO) domieszkowanych magnezem, charakteryzujący się tym, że obejmuje następujące etapy: a) mieszanie acetyloacetonianu żelaza(III), czterowodnego octanu magnezu, eteru dibenzylowego oraz kwasu oleinowego w temperaturze pokojowej; b) doprowadzenie mieszaniny uzyskanej etapie a) do temperatury 190°C - 200°C w ciągu 25 - 30 min.; c) ogrzewanie mieszaniny przez 50 min. w temperaturze 190°C - 200°C; d) ogrzewanie mieszaniny przez 80 min. w temperaturze 230°C - 235°C; e) schłodzenie mieszaniny do temperatury pokojowej i jej przemywanie; f) oddzielanie nanocząstek za pomocą magnesu; g) stabilizacja oczyszczonych nanocząstek stabilizatorem, którym jest mPEG-silan; przy czym, etapy a-g) prowadzone są w atmosferze, którą stanowi powietrze. Kolejnym przedmiotem zgłoszenia są ultramałe supermagnetyczne nanocząstki gamma-tlenku żelaza(III) (USPIO) domieszkowane magnezem otrzymywane sposobem według wynalazku i charakteryzujące się tym, że ich średni rozmiar wynosi 27 - 28 nm, maksymalna magnetyzacja na podstawie rejestracji pętli histerezy wynosi 65 emu/g.
