    摘要: An improved spacer material for improving the biocompatibility of a biomaterial and a method for making it in which a polyalkylimine is covalently attached to an aminated substrate and combined with a crosslinking agent which is at least difunctional in aldehyde groups. The polyalkylimine can be, for example, polyethyleneimine and the crosslinking agent can be, for example, glutaraldehyde. Preferably, the crosslinking agent is applied in dilute solution and at a pH suitable to accomplish light crosslinking of the polyalkyaimine and also provide aldehyde linkages at the interface between the biomolecule and the spacer.

The polyalkylizine can be, for example, polyethyleneimine and the crosslinking agent can be, for example, glutaraldehyde. Preferably, the crosslinking agent is applied in dilute solution and at a pH suitable to accomplish light crosslinking of the polyalkylimine and also provide aldehyde linkages at the interface between the biomolecule and the spacer.

    摘要: A combination ion sensing and reference electrode and a method for producing it. The electrode is formed of bi-lumen plastic tubing using one lumen as sensing chamber and the other as a reference chamber. A portion of the sensing chamber extends distally relative to the reference chamber, and is permeated with an ion selective material by soaking that portion in a solution containing the ion selective material. The method of manufacture is thereby simplified and sealing of the chambers is improved.
