摘要
We describe the construction of a miniaturized module which allows carrying out potentiometric urea determination with the usage of biosensors. The module was fabricated using new hybrid technologies developed in our group which combine ceramic and polymeric materials. Its simplicity and easy way of preparation makes the system very useful for analytical measurements in a flow mode. Application of urease-modified polymer membranes deposited on silver screen-printed electrodes in the module allows to determine urea concentration in clinical range. Moreover, it is a very promising construction for other applications in that other enzymes can be immobilized and various bioanalytes can be determined using this module.
