FORM 9B - PROPOSAL SUMMARY


PROPOSAL NUMBER: B2.01-9728 (For NASA Use Only - Chron: 012271 )
PHASE-I CONTRACT: NAS10-01054
PROPOSAL TITLE: Electrochemical Ethylene Sensor for Monitoring Low Levels in Plant Environments

TECHNICAL ABSTRACT (LIMIT 200 WORDS)
In Phase I Giner, Inc. successfully demonstrated the feasibility of a novel electrochemical sensor that detects gaseous ethylene for NASA?s use in studying the effects of microgravity on plants and in growing plants for use in missions. Ethylene (C2H4) is a plant hormone that is active at very low concentrations in the developmental and reproductive processes of plants. With the Phase I prototype sensor, the detection range for ethylene in air was 22-800 parts per billion (ppb) (volume/volume). The sensor did not experience interference from CO2, N2 or O2, but NO and NO2 did show some cross reactivity on the sensor. Ethylene was successfully detected in headspace samples from cell culture systems with Catharanthus roseus and is being compared to GC/MS analysis of those gas samples. The Phase II goals include: 1) extension of the detection range to 5 to 5000 ppb, by a design change to increase the active sensing area while decreasing background noise 2) extensive validation and improvement of ethylene accuracy and specificity in laboratory and field settings and 3) fabrication of a low power, compact, light instrument for delivery to NASA.

POTENTIAL COMMERCIAL APPLICATIONS
The commercial potential of an accurate, sensitive ethylene monitor extends beyond the plant research community into agriculture and food handling. Commercial uses of the technology include use in optimizing the production, harvest, ripening and storage of fruits and vegetables. The sensor could also be used in conjunction with ethylene generating equipment for ripening or ethylene removal systems. The proposed Giner, Inc technology will be inexpensive, accurate and portable giving it a significant advantage over any existing technology.
