Although DNA origami originally produced nanoarchitectures of purely aesthetic interest, refinements of the technique have opened the door to a range of exciting applications including molecular cages for the encapsulation of molecules,
enzyme immobilization and catalysis, chemical and biological sensing tools, drug delivery mechanisms, and molecular computing devices.
Unlike traditional approaches to immobilize
enzymes, here it is unnecessary to expose the
enzymes to activity - killing reagents or conditions during the
immobilization procedure because all harsh chemical synthesis conditions involved in
immobilization material production were completed before introduction of the
enzyme.
