TECHNICAL ABSTRACT (Limit 2000 characters, approximately 200 words)
Accurate real-time microbial monitoring of water environment is of paramount importance to crew health as well as to ensure proper functioning and control of the life support system during space exploration. The existing methods are time-consuming and labor-intensive, and the devices used are bulky, consumable-hungry, and ill-suited for spacecraft deployment. We propose to develop and demonstrate a novel, fully automated, milli-/micro-fluidics-based sensor cartridge for sample preparation and detection of microbes in water. The final product will be compact, accurate, fully integrated and automated, power-effective, and fieldable in space environments. In Phase 1, key technology elements have been successfully demonstrated. Major components of the sensor cartridge were designed using a computational virtual-prototyping approach followed by state-of-the-art microfabrication and engineering. Experiments with microbial samples commonly found in space water environment were undertaken to demonstrate component functionality and to establish proof-of-concept of the proposed technology. In Phase 2, efforts will focus along two lines. First, component design optimization will be carried out with fabrication enhancements and extended testing and characterization for technology validation. Second, an integrated microfluidic cartridge and instrumentation capable of automated operation (sample processing and detection) will be developed. The prototype instrument will be demonstrated in both terrestrial and hypogravity environments (in collaboration with NASA researchers/facilities). A multi-disciplinary team with experience in all aspects of the proposed effort including fluidic system design, fabrication and experimentation, systems engineering, microbiology and spaceflight has been assembled to ensure successful completion of project milestones.
POTENTIAL NASA COMMERCIAL APPLICATIONS (Limit 1500 characters, approximately 150 words)
The end product of the proposed SBIR effort will be a first-of-its-kind, compact, label-free, fully automated and integrated microbial sensor device for water monitoring. The device will provide NASA a powerful tool for real-time microbial detection and identification, and greatly aid in NASA's efforts to minimize microbial exposure/infection hazard, develop countermeasures, and ensure proper functioning and quality-control of life support system in spacecrafts, space shuttles and space stations. The device will be of direct use to NASA's ground-based research facilities and amenable for space deployment as well.
POTENTIAL NON-NASA COMMERCIAL APPLICATIONS (Limit 1500 characters, approximately 150 words)
The proposed sensor technology will have direct commercial value in both federal and civilian sectors. The device can be used for US Navy shipboard wastewater monitoring or on-field assessment of water quality during military mission. The anticipated civilian applications include:
Pre-clinical and clinical diagnostics (e.g., microbial detection in body fluids)
Public and natural water monitoring (e.g., hospital & health site, recreational and drinking waters)
Industrial wastewater surveillance (e.g., water treatment and food-processing plants)
TECHNOLOGY TAXONOMY MAPPING (NASA's technology taxonomy has been developed by the SBIR-STTR program to disseminate awareness of proposed and awarded R/R&D in the agency. It is a listing of over 100 technologies, sorted into broad categories, of interest to NASA.)
