This core-shell composite can be applied in photothermal, antibacterial, tumor therapy and biological imaging with low dosage and nontoxicity.Īntibacterial gold nanorods layered double hydroxides photothermal conversion tumor therapy. CTAB (cetyltrimethyl ammonium bromide) can be replaced totally during the synthesis process, and GNRs maintain a good dispersion in LDHs. The η value of can reach up to 60% under the 808 nm laser irradiation, which is a significant enhanced conversion efficiency compared with the reported GNR-based photothermal therapy materials. The interaction between Au and LDHs results some electron deficiency on the surface of Au and the more electrons induce more thermal energy conversion. The composite nanorod is composed of SiO 2 core and Au shell, and its cross-sectional view is shown in Fig. S1).Diraction peaks at 26.5, 33.8, 37.9, 51.7, 61.7 and 65.8 degreesare assigned to the rutile phase of SnO2from the FTO substrates(JCPDS no. (2008) Preparation of poly (ethylene oxide)-graft-poly(acrylic acid). In this work, a core-shell composite nanorod is proposed to improve the solar energy absorption performance of the working fluid. The thin PDA shell is bene cial forimmobilizing the enzyme.23The crystal structure of the sampleswas studied by recording their XRD patterns (Fig. The ZIF-8 shell with fine grains (<140 nm) was intergrown well andthe ZnO nanorod core was intact. nanorod/PNIPAAm core / shell nanohybrids via surface initiated ATRP for smart. Figure 5a displays the SEM image of the ZnOZIF-8 coreshell nanorod film. The average diameter of ZnO core is about 100 nm, and the thicknesses of Ag 2 S shell are adjusted from 6 to 35 nm by varying the time of SILAR. Herein, an easy synthesis method is developed to construct the core-shell nanostructure with GNRs and layered double hydroxides (LDHs). The designed ZnOZIF-8 coreshell nanorod film was ob- tained with aHmIM concentration of 0.48 mmol, aH2O/DMF volumeratio of 1:4, and areaction time of 20 hours. ZnO/Ag 2 S coreshell nanorod arrays (NRAs) are successfully fabricated via chemical bath deposition procedure and subsequent successive ionic layer adsorption and reaction (SILAR) technique. Photothermal conversion efficiency (η) of gold nanorods (GNRs) can be tuned by enlarging the aspect ratio and forming the core-shell structure.
