and cartilage. The company develops and commercializes the Arthro-BSTTM, an arthroscopic probe used for_x000D_
precise, non-destructive assessment of articular cartilage. Arthro-BSTTM measures streaming potentials_x000D_
generated during compression of articular cartilage during an arthroscopic procedure and assesses its_x000D_
electro-mechanical properties. To ensure reliable local streaming potential measurement by an individual_x000D_
microelectrode (37 microelectrodes, each with a geometric surface: 20µm x 80µm), a sophisticated_x000D_
current-voltage transducer is used. When the device is surgically introduced into the knee, small air bubbles_x000D_
tend to form on the microelectrodes' surfaces, which create electrical fluctuations that cause a significant delay_x000D_
before the probe can perform useful measurements. Improving hydrophilicity (wettability) of the_x000D_
microelectrode array should greatly reduce air bubble formation, which in turn should significantly reduce_x000D_
electrical equilibration time during arthroscopy. In this project, two separate surface treatment methods will be_x000D_
tested on the microelectrode array, both designed to increase wettablity: (i) Pluronic® brush-coating; (ii)_x000D_
