Figure 9

A) Signaling aptamers by one-chain molecular beacon approach. An aptamer sequence is extended so that it can be formulated into a molecular beacon. B) Signaling aptamers by two-chain molecular beacon approach. An aptamer is split into two chains, one of which is formulated into a molecular beacon. C) Signaling aptamers by two-chain molecular assembly. An aptamer is split into two chains, each of which is labeled with a fluorophore or a quencher. This figure is adapted from ref. 86.
