摘要：

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. © 2005 Wiley-VCH Verlag GmbH & Co. KGaA, Weinheim.
