A self-assembling DNA system has now been designed to perform complex pattern recognition ... work 6 on DNA-tile assembly can support the design of sophisticated new experiments.

1 These structures are referred to as pathogen-associated molecular patterns, and the receptors of the innate immune system that evolved to recognize them are called pattern-recognition receptors.

In humans, pattern-recognition systems in the intestine involving Toll-like receptors scan the physical structure of different bacteria to sense the presence of infectious microorganisms.
