Surface modification of magnetite nanoparticles using gluconic acid and their application in immobilized lipase

Surface Modification of Alumina Nanoparticles: A Dispersion Study in Organic Media

“…2a) is due to stretching frequency of Al-O in Al 2 O 3 . 31 The broad peaks at around 3442 and 1630 cm -1 are attributed to the stretching and bending bands of O-H groups on the surface of alumina, respectively.…”

Effects of surface modification and activation of magnetic nanoparticles on the formation of amylase immobilization bonds under different ionic strength conditions

“…A c c e p t e d M a n u s c r i p t 6 In the present work, mechanisms of amylase immobilization on Fe 3 O 4 MNPs were investigated in different conditions. Surface treatment of MNPs was carried out through two coating methods with different densities of amino groups on the surface of MNPs.…”

“…covalent bond) and physical immobilization of the enzymes on supports [4,5]. For catalytic applications, immobilization through the covalent bond between the enzyme Page 5 of 44 A c c e p t e d M a n u s c r i p t 4 and carrier has been proposed, because the amount of enzyme released from the carrier within the chemical process would be minimum under this condition [6]. However, controlling the immobilization conditions is necessary for reaching the optimum immobilization value and activity of biocatalysts, as the formation of a chemical bond between the enzyme and support, in covalent immobilization method, can potentially cause conformational changes in the structure of the enzyme and variations in its catalytic activity [7].…”

Recombinant surface engineering to enhance and expand the potential of biologically produced nanoparticles: A review

“…Such cross-linking agents are supplied externally to the particle surface, after which proteins of interest which are synthesized and purified separately are added to interact with the cross-linking agents [16][17][18], such that they are presented on the surface of the particles. By contrast, living organisms are natural displayers of proteins onto the surface of BNPs [1, 2, 5-9]: during the particle synthesis process, the surface proteins, produced with the appropriate modifications to their functions, are naturally displayed [10].…”
