“…Amorphous silica is characterized, among other properties, by the presence of silanol groups (-Si-OH) on its surface providing negative surface charge for pH > 3 (Yiu et al, 2001). Silica coating onto magnetic nanocompounds may cause difficulty because of its structure, which makes it impossible the formation of a uniform layer onto the surface of maghemite.…”

“…Нові можливості для опти-мізації методів адсорбції відкриваються завдя-ки швидкому прогресу в галузі синтезу мікро-та наночастинок з заданими властивостями. Мезопористі матеріали мають велику площу поверхні кристалу та можуть нести різнома-нітні хімічні групи, які можуть бути корис-ними при іммобілізації біоматеріалу [5]. Зо-крема, до таких мезопористих мікрочастинок належать силікаліти та мезопористі кремнієві сфери (МКС), які і були використані в даній роботі; для порівняння був використаний мі-кропористий цеоліт L.…”

“…Functionalised MPS can be prepared directly, post-synthesis and by the addition of bridged silesquioxanes as the source of silica. MPS modified with functional groups such as thiol, amine, chloro, carboxylic acid, N-(trimethoxysilylpropyl)ethylene diamine triacetic acid (EDTA), oxirane rings, cyano, alkane and aromatic functional groups together with a range of metal ions have been prepared [8][9][10][11][12][13][14][15][16][17].…”

“…Post-synthesis functionalization involves direct grafting of a suitable functional group onto the surface of MPS and has been used to graft chloro, alkoxy, and silyl and amine groups [8][9][10][11][12][13][14][15] onto the exposed surfaces of the mesoporous channels and external surface. The advantages of post-synthesis functionalization include the fact that no alteration of the structural ordering of the starting mesoporous material occurs and that functionalization occurs only on the surface.…”
