Continuous subcutaneous glucose monitoring in diabetic patients: a multicenter analysis.

Objective: To evaluate the accuracy of a new subcutaneous glucose sensor (Glucoday; A. Menarini Diagnostics) compared with venous blood glucose measurement in type 1 and type 2 diabetic patients.

Research Design: A multicenter study was performed in 70 diabetic patients.

An electrochemical multienzymatic biosensor for determination of cholesterol.

This paper describes an electrochemical biosensor for free cholesterol monitoring. The sensor is a multienzymatic electrodic system in which horseradish peroxidase and cholesterol oxidase are simultaneously immobilized within a polymeric film, on the surface of a pyrolitic graphite electrode. From voltammetric and amperometric (flow-injection) data obtained, the efficiency, reproducibility and stability of the system are discussed.

Analytical performance of an heterogeneous enzyme immunoassay using the same separation system.

A single "one step" solid phase sandwich enzyme immunoassay was developed. The assay employs two monoclonal antibodies with affinity and specificity for different epitopes of the analyte: one is covalently coupled to peroxidase, while the other one is coupled to biotin. The addition of the reagent to an avidin-coated strip gave a specific and efficient mean for binding the sandwich complex to the solid phase, via the high affinity interaction between biotin and avidin.
