Figure 1. From microarrays to gel particle arrays.

Figure 1

Cartoon depiction of technology advancements that led to creation of hydrogel particle arrays. Spots on microarrays were first translated into hydrogel spots functionalized with biological probes. Techniques were then established to fabricate free-floating hydrogel particles that were similarly functionalized and could be suspended in solution for assays.
