- *Abstract
-
Researchers at the University of California have developed an implantable analyte sensor fabricated using an improved porous membrane. A special property of the membrane is a defined pore size, which has a small size distribution (+/- 1%-5%) compared to the size distribution of standard membranes. These membranes can exclude interfering molecules, such as proteins, which could otherwise cause major drift problems for a sensor implanted in vivo.
The membrane of this analyte sensor may be fabricated such that it has a glucose diffusion test of at least 1mg/dl in 330 minutes, and an albumin diffusion test of at most 0.1g/dl in 420 minutes.
