• recent research on tetrazoles, 1-substituted 1H-1,2,3,4-tetrazoles was found to be a special category due to their biological activity [16]. The plant biosynthesis of nanoparticles immobilized on natural supports is a subject of new research as little has been published on this topic [17][18]. Therefore

The findings demonstrate the complexity of reactions in terms of protein biosynthesis and protein release – even alterations of the cellular vesicular transport are conceivable. It cannot be excluded that cell material of dead cells could
