Abstract
New generation delivery systems involve smart materials such as shape memory and self-folding polymers. Shape memory polymers revert back to their original shape above their glass transition temperatures where this temperature change can be induced con‐ ventionally, photolytically, with a lazer or magnetically depending on the composition of the material. This ability to assume original shape upon a trigger can be used in deliver‐ ing drugs, DNA or cells. Self folding polymers are a new class of materials which may be composed of multilayers with different thermal expansion coefficients or with hinges that allow folding upon being triggered. These new materials allow various architectural de‐ signs of smart delivery vehicles predominantly for DNA and cells. The aim of this chap‐ ter is given shape and folding polymers and their usage for drug delivery systems.
