ATP Bioluminescence

BTC is working collaboratively in the area of Bioluminescence - Detection of ATP from bacterial cells. The first assay is related to a generic bacterial detection system to determine general contamination. Through these efforts, we can identify specific bacteria with the inclusion of specific phage lytic enzymes (gram positive lytic enzyme detection).

The bioluminometer shown here is able to determine the presence of low levels of viable bacteria and as few as 100 spores. The system generally provides results within five minutes for bacterial detection and within 20 minutes for spore detection.

hand held assay (hha)

The SMART assay was the first rapid hand held assay developed in 1986 by the NHD team.  In a new advancement to Hand Held Assays, the polymer enhanced SMART lateral flow assay provides an increase of up to 1 log in sensitivity as part of the first bio-defense test used since Desert Storm I in 1991. This new assay can be used for the detection of unknown bacteria, viruses and toxins for defense, food, animal or environmental applications.

Desert Storm
During the Gulf War we deployed 17 research and development systems to the Gulf region to monitor the air for suspected Iraqi Biological Warfare (BW) agents. Twelve of the 17 systems were mobile, and consisted of the Army’s XM-2 high volume air samplers and Sensitive Membrane Antigen Rapid Test (SMART) identification tickets.

Fluorescence Immunoassay System

Fluorescence Immunoassay System

BTC also is working with partners on the development of a Membrane Enhanced Fluorescence Immunoassay System with specific monoclonal antibodies for the rapid and sensitive detection of bacteria, viruses and toxins based on immunological (antibody-antigen) reactions. A combined 180 degree optical/membrane configuration will be employed for rapid, high sensitivity and simple determination of low concentrations of target substances such as bacteria, spores and viruses.

The fluorescence antibody mixture is immobilized on a carefully selected translucent membrane with appropriately low fluorescence background and high sensitivity characteristics.
