Silica-based surface molecular imprinting for recognition and separation of lysozymes

Abstract

A highly selective surface molecularly imprinted inorganic polymer composed of tetraethoxysilane and 3-aminopropyltriethoxysilane has been prepared by a sol–gel process on silica submicroparticles in aqueous solution under simple and mild conditions.

Novel polydopamine imprinting layers coated magnetic carbon nanotubes for specific separation of lysozyme from egg white

“…protein is summarized briefly in Table 3. As can be seen, the resultant nanomaterials prepared in this work has a higher IF than those of other polymers [19, [35][36][37][38][39][40][41]. From this comparison, it can be found that MCNTs@Lyz-MIPs reported here constitute a significant improvement.…”

“…10,11 Molecularly imprinted polymers (MIPs) are articial recognition materials with cavities that are formed by polymerization of functional monomers and cross-linkers around a target molecule aer template removal to specically bind that molecule. 12,13 They allow both sample pretreatment and enrichment and have been used in separation media, 14 and to mimic antibodies 15 as well as in chemical and biochemical sensing. 16 Molecularly imprinted solid-phase extraction (MISPE), which combines MIPs with SPE, has high selectivity, specicity and separation ability.…”

“…Surface imprinting using silica as the support has been applied to imprint pharmaceuticals [13][14][15][16][17][18] and biological macromolecules. 9,[19][20][21][22][23][24][25][26][27][28][29] Regrettably, the surface imprinting technology to prepare amino acid MIPs has been seldom reported.…”
