Schematic illustration of hydrogel‐based mRNA detection by a shape‐encoding intraplex hydrogel microparticle. The particle in stripe shape contained a reference fluorophore as positive control (yellow, channel 1) and blanks as negative controls (gray, channel 2 and 6). Channel 3–5 were used for the simultaneous detection of three different targets. Inert PEG600 was added as a porogen to enhance mass transport, whereas PEG diacrylate was used for the hydrogel formation.
