  • Publication number: 20230176042
    Abstract: Compositions comprising multiple hydrogel particles having substantially the same diameter, but with each subgrouping of particles from the multiple hydrogel particles having different associated values for one or more passive optical properties that can be deconvoluted using cytometric instrumentation. Each hydrogel particle from the multiple hydrogel particles can be functionalized with a different biochemical or chemical target from a set of targets. A method of preparing hydrogel particles includes forming droplets and polymerizing the droplets, with optional functionalization.
