研究目的
Investigating the dual thermal and photo-switchable plasmonic circular dichroism (PCD) in noble metal nanostructures through a supramolecular strategy involving guanosine, deoxyguanosine, and boric acid modified achiral gold nanorods.
研究成果
The study successfully demonstrated a supramolecular strategy for achieving dual thermal and photo-switchable PCD in noble metal nanostructures. The hybrid hydrogel showed reversible PCD properties under thermal and photo-irradiation, with selective response to circularly polarized light, indicating potential applications in phototherapy and drug delivery.
研究不足
The study is limited by the specific conditions required for the formation of the hybrid hydrogel and the induction of PCD. The reversibility and stability of the PCD under repeated thermal and photo-switching cycles may also pose challenges for practical applications.
1：Experimental Design and Method Selection:
The study involved the co-assembly of guanosine (G), deoxyguanosine (dG), and boric acid modified achiral gold nanorods (GNRs) into a hydrogel to produce hybrid nanofibers with PCD. The methodology included the use of dynamic borate ester bonds for chiral induction and the investigation of thermal and photo-switchable properties of the PCD.
2：Sample Selection and Data Sources:
G, dG, and GNRs were used as the primary materials. The samples were characterized using SEM, UV-vis, and CD spectroscopy.
3：List of Experimental Equipment and Materials:
Gold nanorods modified by phenylboronic acid, guanosine, deoxyguanosine, and various chemicals for synthesis and characterization.
4：Experimental Procedures and Operational Workflow:
The synthesis of GNRs, preparation of hybrid hydrogels, and their characterization under varying temperatures and light irradiations.
5：Data Analysis Methods:
The analysis of PCD signals, photothermal performance, and selective response to circularly polarized light (CPL) was conducted using UV-vis and CD spectroscopy.
