✦ Synopsis

The creation of microlenses from hydrogel microparticles is demonstrated. The fabrication of substrate‐supported microgels is performed using electrostatic interactions between aminopropyltrimethoxysilane‐functionalized glass substrates and acrylic acid groups present on the microgel surface. The lensing ability is illustrated by imaging a photomask through each of the microgels present on the surface (see Figure).
