Abstract: A hydrogel material for modulating an immune response in a human subject or other mammal includes a collection of microgel particles having one or more network cross linker components, wherein the microgel particles, when exposed to an endogenous or exogenous annealing agent, links the microgel particles together in situ to form a covalently-stabilized scaffold of microgel particles having interstitial spaces formed between the microgel particles and wherein the collection of microgel particles further includes at least one of an antigen and an adjuvant.

Abstract: A hydrogel material for use in a human subject or other mammal includes a collection of microgel particles having one or more network cross linker components, wherein the microgel particles, when exposed to an endogenous or exogenous annealing agent, links the microgel particles together in situ to form a covalently-stabilized scaffold of microgel particles having pores formed between the microgel particles wherein the pores are substantially devoid of hydrogel.

Abstract: A microporous gel system for certain applications, including biomedical applications, includes an aqueous solution containing plurality of microgel particles including a biodegradable crosslinker. In some aspects, the microgel particles act as gel building blocks that anneal to one another to form a covalently-stabilized scaffold of microgel particles having interstitial spaces therein. In certain aspects, annealing of the microgel particles occurs after exposure to an annealing agent that is endogenously present or exogenously added. In some embodiments, annealing of the microgel particles requires the presence of an initiator such as exposure to light. In particular embodiments, the chemical and physical properties of the gel building blocks can be controlled to allow downstream control of the resulting assembled scaffold. In one or more embodiments, cells are able to quickly infiltrate the interstitial spaces of the assembled scaffold.

Abstract: A biocompatible analyte sensing material for intradermal or subcutaneous application includes a collection of microgel particles having one or more network crosslinker components and an endogenous or exogenous annealing agent that links the microgel particles together in situ to form a covalently-stabilized scaffold of microgel particles having interstitial spaces therein. A plurality of analyte-specific fluorophores are conjugated to the microgel particles, wherein the analyte-specific fluorophores, in the presence of the analyte and subject to excitation radiation, emit fluorescent light. The analyte sensing material may, in some embodiments, be applied to an excision made in the skin or injected into the skin of a subject.
