Abstract

See full text

A lab-on-a-cartridge (LOAC) handheld assay device including an integrated test cartridge, a carbon nanotube electrode sensor, and a reagent dispenser for dispensing a liquid reagent into the test cartridge. The test cartridge includes a syringe plunger for drawing a test fluid into a test cavity, a bottom wall with a reagent inlet port, and a vibration adaptor for mixing. The reagent input port is attached with a slit valve for engaging with a slit spout of the reagent dispenser as a needleless dispensing system. Carbon nanotube sensors of different three-electrode configurations are provided for testing a volume of test fluid to increase the electrochemical reaction sensitivity. The assay device can be used with a CNT three-electrode sensor for saliva testing for determining glucose concentration.
