[ 1 ] - Ultrasound effects on the activity of free and immobilized urease on the magnetic nanoparticles and silica gel

In this study, the effect of low-frequency ultrasound on the structure and activity of urease enzyme has been investigated. For this purpose, the enzyme was exposed to ultrasound with 20 kHz frequency at different time intervals. The urease enzyme was immobilized on the surface of magnetic nanoparticles (Fe2O3), and activated silica gel with 89% and 66% efficiency respectively. The enzyme activ...
