Light through a lens : 2D microlens arrays composed of temperature‐ and pH‐responsive poly( N ‐isopropylacrylamide‐co‐acrylic acid) microgels assembled on Au nanoparticles have been prepared (see SEM image). Optical properties of the arrays can be modulated locally and reversibly in response to illumination with a Nd:YAG laser.
