CBGI is currently developing an innovative water testing system,
a Multiple Simultaneous Immunologic/Reagent Testing System (M-SIRTS),
in which common chemicals and biologicals and their concentrations
can be detected by using standard reagent chemistry and colorimetry
and/or a unique form of immunoassay/ELISA test.
The M-SIRTS uses a hand held, three part cassette to both take
the sample and to process it. The sample is captured and them
processed within the cassette. The cassette is then put into
a portable detector which reads the color of the sample/reagent
in each well to determine the concentration of analyte. The
current planned configuration of the cassette includes 100+
wells, which would enable simultaneous sampling of a number
of chemical or immunological tests as well as the necessary
calibration wells within 10 minutes. We also have a cassette
that can detect organisms such as e. coli in concentrations
as low as 1 per 100 mL.
Currently, CBGI has a functional cassette prototype and has
demonstrated “proof of concept” for colorimetric
detection of a variety of chemicals. There are three separate
aspects of the CBGI technology, two revolutionary and one inventive.
The revolutionary aspects are the test cassette designs (small-well
and large-well) and the immunological assays (Single-Step Immunological
Assay, SSIA, and Single-Step Immunological Assay for Multiple
Analytes, SSIAMA). The inventive parts are the detector that
brings the whole system together and the way our cassette and
detector technology allow the use of standard laboratory reagent
chemistry and colorimetry in a completely new way.
M-SIRTS can be packaged as: 1) portable/field deployable units,
2) free-standing laboratory units, 3) in-line process units,
4) submersible autonomous continuous monitoring units, and 5)
free-standing retail kiosks.
