In one configuration, a handheld compound tester to process and detect presence of a compound in a tablet is disclosed. The handheld compound tester may include a sampling chamber configured to receive a tablet and a lid couplable with the sampling chamber. The coupling of the lid with the sampling chamber may cause cutting of the tablet. A liquid may be added inside the sampling chamber to create a mixture with segments of the tablet. The mixture may be then received by a housing adjoining the sampling chamber. A test strip disposed within the housing, upon contacting the mixture, may be configured to indicate a presence of the compound in the mixture.

Microfluidic droplet generators

Disclosed herein is a novel method of producing monodisperse aqueous droplets, as well as a novel microfluidic droplet generator. In some examples, the method comprises flowing an aqueous solution through a microchannel and into a sample reservoir of the microfluidic droplet generator, wherein monodisperse droplets of the aqueous solution form by step-emulsification at a step change in height at an intersection of a reservoir end of the microchannel and a sidewall of the sample reservoir. In some examples, the aqueous solution is a hydrogel precursor solution and monodisperse droplets of the hydrogel precursor solution form by step-emulsification at the step change in height at the intersection of the reservoir end of the microchannel and the sidewall of the sample reservoir. In some examples, the monodisperse droplets of the hydrogel precursor solution are incubated under conditions suitable for gelation to form hydrogel beads.
