Present Status of Application of Sol-Gel Technique in Electrochemical and Biological Sensors

A review on the present status of application of Sol-gel technique in electrochemical and biological sensors,covering mainly the years from 1992 to 2006,was given in this paper,focusing specially on the methods of preparation of electrochemical and biological sensors using Sol-gel technique to encapsulate electrochemically active substances or biologically active molecules,and the related principles,on the influential factors on the preparation of such censors and on its analytical applications.A brief discussion on its trends of development was also given (51 ref.cited).
