Hydrogels can release drugs one at a time - A hydrogel that can be programmed to release different protein drugs one after the other rather than all at once could simplify the delivery of complex therapeutic regimens for various diseases. Researchers have used aptamers to functionalise a hydrogel made from natural polysaccharides to this end. Sequences of DNA that complement the aptamers then allow the proteins to be released at different stages.(10.1021/ja305238a)
