(A) Bilingual PNA biopolymers contain hydrophobic and hydrophilic amino acid residues at the γ-position to direct self-assembly. Upon the introduction of a complementary sequence, nucleobase recognition induces stimuli-responsive disassembly. (B) Changes to the amino acid code (R1, R2) do not significantly impact assembly. (C) Nucleic acid sequence truncation allows for control over assembly size.
