This review covers the area of bioapplications of layer-by-layer assembled polymer planar films and microcapsules-biologically relevant responses stimulated by light. We present recent progress in light-stimulated release of bioactive molecules from the assembled structures. Functionalization of the films with metal nanoparticles and bioactive molecules that provide the films with light sensitivity and reservoir properties is also described. The use of these films in the delivery of bioactive molecules is closely related to light-induced cargo release from capsules; this promising method of intracellular delivery is also addressed.
