Abstract: A device for rapidly collecting tissue samples from organisms serves as a reaction chamber. It includes a solvent used to extract the analyte, a filter, and optional bioconcentrators. The filtered suspension is irradiated with a predetermined wavelength and the emitted, scattered, or reflected photons transmitted to a detector that identifies and quantifies the analyte. The bioconcentrators may consist of antibodies and colloidal metal nanoparticles that enhance emission of Raman signal frequencies by analytes bound to the antibodies. Alternatively, the device may contain only the extraction solvent and a filter.

Abstract: An immunological test kit suitable for the rapid detection of ciguatoxin and related low molecular weight lipid polyether marine toxins in fish tissues in the field, home or laboratory. The test procedure utilizes a synthetic membrane laminated onto one end of a solid plastic stick, which is immersed into alcohol with a piece of fish tissue. The membrane is then removed and dried thoroughly, then placed in the suspension of mixed colored beads coated with anti-ciguatoxin. The membrane is then rinsed in water and the intensity of the color compared with a standard range of colors formed (0-3+). The color intensity is proportional to the concentration of toxin in the piece of tissue. The kit includes the synthetic membrane on a plastic stick, a suspension of mixed colored beads coated with anti-ciguatoxin antibody, testing instruments, and a supply of solvent.
