Abstract: | Patterned arrays of light‐responsive microchambers are suggested as candidates for site‐specific release of chemicals in small and precisely defined quantities on demand. A composite film is made of poly(allylammonium)‐poly(styrene sulfonate) multilayers and gold nanoparticles incorporated between subsequent stacks of polyelectrolytes. The film shaped as microchambers is loaded with colloid particles or oil‐soluble molecules. The microchambers are sealed onto a glass slide precoated with an adhesive poly(diallyldimethylammonium)‐poly(styrene sulfonate) multilayer film. A focused laser beam is used for remote addressing the individual microchambers and site‐specific release of the loaded cargo. |
