text: The secondary structures of aptamers mainly consist of short helical arms and single stranded loops, defined by intramolecular base complementarity, whereas tertiary structures of aptamers result from a combination of these secondary structures with pseudoknotting of segmental sequence complementarity of loops and bulges and allow aptamers to bind target by noncovalent interactions like Van der-Waals interactions, hydrogen bonding, topological compatibility, stacking of aromatic rings, and electrostatic interactions .
