Ultrasound Assisted Non-Seeded Method OnudSurface Modification Of SuperparamagneticudIron Oxide Nanoparticles For MagneticudResonance Imaging Probe

摘要

Dalam tesis ini, satu kaedah baru tanpa benih dan ultrasonik mudah untukudmenggabungkan SPION ke dalam silica telah dibangunkan dan dianalisa. Campuranudkedua-dua nanopartikel SPION dan silika yang di sintesis secara berasingan oleh kaedahudmendakan-bersama dan sol-gel, masing-masing telah dikenakan pancaran secaraultrasonik pada julat pH yang berbeza antara 3 dan 5. ududIn this thesis, a new non-seeded and facile ultrasonic method of incorporatingudSPION into silica was developed and analysed. Mixture of both SPION and silicaudnanoparticles synthesized separately by co-precipitation and sol-gel method, respectivelyudwas ultrasonically irradiated at different pH ranges between 3 and 5.
