US Patent:

20180292369, Oct 11, 2018

Filed:

Jun 8, 2017

Appl. No.:

15/617798

Inventors:

Kathleen Stitzlein - Millersburg OH, US

International Classification:

G01N 30/95
G01N 30/94

Abstract:

A field testing device is provided for quantitating psychoactive components of marijuana such as THC in biological fluids such as saliva. Such a device may include an HPTLC plate for separating interferents from THC and may also include fluorometric components for quantitating THC. The device may include a microprocessor adapted to relate fluorescent intensity to analyte concentration through one or more calibration curves. Devices may optionally include microfluidics for carrying out HPTLC on biological samples including sample reservoirs, reagent reservoirs, micro-pumps, mixers, and the like.

International Classification:

G01N 33/94
B01L 3/00

Abstract:

A microfluidic device for on-site quantitative detection of marijuana in body fluids has a body fluid collecting reservoir for receiving a body fluid and an anti-THC antibody reservoir that retains anti-THC antibodies. A first micromixer receives the body fluid from the body fluid collecting reservoir and the anti-THC antibodies from the anti-THC antibody reservoir to form a sample mixture. The device further comprises a fluorescein-THC conjugate reservoir that fluorescein-THC conjugate; a second micromixer that receives the sample mixture and the fluorescein-THC conjugate to form a test mixture; and at least one light source to emit an excitation wavelength and at least one detector to receive an emission wavelength.
