Lab-on-a-chip sensor for monitoring of oceanographic chemical parameters Navy SBIR FY2016.1 Sol No.: Navy SBIR FY2016.1 Topic No.: N161-065 Topic Title: Lab-on-a-chip sensor for monitoring of oceanographic chemical parameters Proposal No.: N161-065-0470 Firm: HJ Science & Technology, Inc. 820 Heinz Avenue Berkeley, California 94710 Contact: Hong Jiao Phone: (408) 464-3873 Web Site: http://www.hjsciencetech.com Abstract: In this Phase I SBIR effort, HJ Science & Technology proposes to demonstrate the feasibility of an integrated and fully automated "lab-on-a-chip" (LOC) sensor capable of autonomous and in-situ high sensitivity and precision measurement of oceanographic chemical parameters. Our innovation stems from our patent pending valve-less fluidic switching (VLFS) technology that we have developed for a myriad of microfluidic automation applications. The LOC sensor is compact and inexpensive with a full automation capability, specifically designed to perform autonomous measurements with sensitivity and precision that are only currently achievable with laboratory-based instruments. During Phase I, we will develop the LOC sensor to meet the precision requirement of measuring chloride, bromide, sodium, calcium, sulfate, sulfide, and conductivity. During Phase I Option, we will integrate the commercially available miniature temperature, pH, and dissolve oxygen sensors to our LOC sensor. The overall Phase I goal is to determine the feasibility for the development of the ruggedized LOC sensor that can be integrated into a shipboard corrosion control system. We will demonstrate this feasibility through simultaneous sensing of all the key oceanographic chemical parameters in a laboratory environment in order to meet the design and performance metrics required for in-situ monitoring. Benefits: The proposed LOC sensor is designed to be integrated into Navy's shipboard corrosion control system. In addition, the proposed LOC sensor technology has application in commercial ship hull corrosion protection where previously impressed current corrosion protection has been impractical due to the ongoing maintenance and calibration requirements of such systems. Because our LOC sensor can measure all ionic analytes, its analytical capability extends far beyond the chemical parameters for corrosion control to include a broader class of in-situ environmental monitoring of water-based analytes.
