Abstract
In accordance with the present disclosure, an example non-transitory computer readable medium may store instructions that when executed cause a computing device to dispense, using a first fluid ejector of a microfluidic device, a biologic sample to a region of a substrate, dispense, using a second fluid ejector of the microfluidic device, a reagent to the region of the substrate, and dispense, using a third fluid ejector of the microfluidic device, a metabolic indicator to the region of the substrate, wherein the metabolic indicator provides a visual indication in response to reaction with the biologic sample.
Claims15
A non-transitory computer readable medium storing instructions that when executed cause a computing device to:
- dispense, using a first fluid ejector of a microfluidic device, a biologic sample to a region of a substrate;
- dispense, using a second fluid ejector of the microfluidic device, a reagent to the region of the substrate;
- and
- dispense, using a third fluid ejector of the microfluidic device, a metabolic indicator to the region of the substrate, wherein the metabolic indicator provides a visual indication in response to reaction with the biologic sample.
An apparatus, comprising:
- a dispense head including:
- a first fluid ejector of a microfluidic device to dispense a biologic sample to a region of a substrate;
- a second fluid ejector of the microfluidic device to dispense a reagent to the region of the substrate;
- and
- a third fluid ejector of the microfluidic device to dispense a metabolic indicator to the region of the substrate, wherein the metabolic indicator provides a visual indication in response to reaction with the biologic sample;
- and
- an imaging device to obtain a measurement of the metabolic indicator.
