Regenerated Cellulose Films with Amino-Terminated Hyperbranched Polyamic Anchored Nanosilver for Active Food Packaging

“…The bands at 1467 cm –1 were related to the bending vibration of −CH 2 – . >CO stretching vibration of amide bond and NH bending vibration appeared at 1649 and 1557 cm –1 . The band at 3430 cm –1 was related to the superposition of the stretching vibration of −NH 2 and stretching vibration of −NH– in an amide bond .…”

“…39 >CO stretching vibration of amide bond and NH bending vibration appeared at 1649 and 1557 cm −1 . 40 The band at 3430 cm −1 was related to the superposition of the stretching vibration of −NH 2 and stretching vibration of −NH− in an amide bond. 41 After reduction of AgNO 3 , the stretching peak of >CO and the bending absorption peak of −NH− were moved from 1649 and 1557 cm −1 to 1652 and 1575 cm −1 , respectively, and the superimposed peak of −NH 2 stretching vibration and −NH− stretching vibration moved from 3430 to 3445 cm −1 .…”

Solvothermal synthesis of FeCo nanoparticles for magneto-controllable biocatalysis

“…Magnetic nanoparticles (MNPs) with well-dened nanoscale structures and unique properties have attracted tremendous research efforts because of the potential applications in many elds, 1,2 such as magnetic resonance imaging, 3,4 drug delivery, [5][6][7] environmental remediation, 8 chemical sensors, 9 bioseparation 10,11 and biocatalysis. 12 Among various magnetic nanomaterials, FeCo nanoparticles (FeCo NPs) exhibit exceptional magnetic properties, including high Curie temperature, the highest saturation magnetization and high permeability.…”

Magnetic nanoparticles coated with immobilized alkaline phosphatase for enzymolysis and enzyme inhibition assays

“…Magnetic nanoparticles are advanced materials that have potential use as supports for biomacromolecules, such as nucleic acids, antibodies, peptides and enzymes. [1][2][3][4][5] Magnetic nanoparticles with immobilized enzymes or proteins possess several notable advantages due to their novel nanostructures and magnetic properties. Such nanoparticles can provide a biocompatible and inert microenvironment that does not interfere with the native properties of enzymes or proteins, thus retaining their biological activities.…”
