Nucleic acid-polymer conjugates are an attractive class of materials endowed with tunable and responsive character. Herein, we exploit the dynamic character of nucleic acids in the preparation of hybrid DNA-covalent polymers with extendable grafts by the hybridization chain reaction. Addition of DNA hairpins to an initiator DNA-dextran graft copolymer resulted in the growth of the DNA grafts as evidenced by various characterization techniques over several length scales.

Article Synopsis
- This study explores whether spin crossover molecules maintain their functionality when integrated into a device, specifically gold nanoparticle arrays featuring a specific room-temperature spin crossover molecule, Fe(S-BPP)2.
- Three experimental techniques—temperature-dependent Raman, magnetization measurements, and charge transport assessments—are employed to analyze the molecular-nanoparticle structures and confirm that spin transitions occur within the arrays.
- Results show a unique resistance minimum in temperature-resistance curves for the Fe(S-BPP)2 device, suggesting that this behavior is linked to spin transitions and differs from passive molecule networks, with theoretical backing indicating higher resistance in the high spin state compared to the low spin state.
