Cup with integrated lateral flow assay for detecting caffeine content

Abstract

The present disclosure discusses a novel cup designed with an integrated lateral flow assay (LFA) to detect the presence of caffeine in coffee. The LFA is housed in a specialized chamber in a selected position or at the bottom of the cup. This chamber is designed with an opening only at the bottom, which traps air when the cup is filled with liquid, ensuring that only the bottom part of the LFA is wetted by the beverage. This design allows the LFA to function effectively, provided the coffee does not contain milk or other additives that could interfere with the test. The invention includes a transparent window on the cup to allow the user to observe the LFA and determine the caffeine content visually. Additionally, the cup can be modified or retrofitted with LFA chambers that can be attached to existing cups or stand inside them like a straw.
