Biocatalyst biosensors
WebFeb 8, 2011 · Standard immobilizations are not fully random processes, but the protein orientation may be difficult to alter. Initially, most efforts using this idea were addressed towards controlling the orientation of the enzyme on the immobilization support, in many cases to facilitate electron transfer from the support to the enzyme in redox biosensors. WebA large number of potentiometric urea biosensors are reported in the literature because urease is a cheap and stable biocatalyst that is widely used as model enzyme for the development of new enzyme immobilization protocols, new urea-sensitive materials and new sensing schemes. pH-sensitive urea biosensors.
