Abstract
A sterile device immersed in a sterile buffer and a method for providing same. The sterile device may be a medical device such as a biosensor having a biomolecule as a sensing element such as, for example, a glucose oxidase enzyme. The buffer may be a bicarbonate solution. Both the device and the buffer may be packaged and stored over long term while maintaining sterilization. The sterilization method may comprise a combination of gaseous, liquid and light sterilization.
