Multifunctional nanoprobes are designed to own various functions such as tumor targeting, imaging and selective therapy, which offer great promise for the future of cancer prevention, diagnosis, imaging and treatment. Herein, silica was applied to replace cetyltrimethylammonium bromide (CTAB) molecules on the surface of gold nanorods (GNRs) by the classic(More)
BACKGROUND Melanoma is known to be radioresistant and traditional treatments have been intractable. Therefore, novel approaches are required to improve the therapeutic efficacy of melanoma treatment. In our study, gold nanorods conjugated with Arg-Gly-Asp peptides (RGD-GNRs) were used as a sensitizer to enhance the response of melanoma cells to 6 mV(More)
Indocyanine green-loaded mesoporous silica-coated gold nanorods (ICG-loaded Au@SiO2) were prepared for the dual capability of X-ray computed tomography (CT) and fluorescence imaging. X-ray CT scanning showed that ICG-loaded Au@SiO2 could provide significant contrast enhancement; Near-infrared fluorescence generated by the nanomaterial was present up to 12 h(More)
Metallic glass film of Pr<sub>60</sub>Al<sub>10</sub>Ni<sub>10</sub>Cu<sub>20</sub> is proposed to be used as a resist of phase-change lithography (PCL). PCL is a mask-less lithography technology by using laser-direct-writing to create the intended nanopatterns. Thermal distribution in the PrAlNiCu film after exposure is calculated by finite element method(More)
We explored the biocompatible gold nanoparticles (GNPs) with surface modified by chitosan in the applications of cell's response to X-ray irradiation. Substantial amounts of chitosan modified gold nanoparticles (CS-GNPs) were found to be internalized in cell cytoplasm revealed by transmission electron microscopy. Their in vitro cytotoxicity effects on(More)
A hydrophilic indocyanine green derivative (ICG-Der-02) was covalently doped into mesoporous silica-coated gold nanorods (AuNRs/mSiO2). The self-synthesized derivative offers one carboxyl functional group on a side chain, which enables ICG-Der-02 to be covalently linked to nanomaterials and reduces the probability of leakage/desorption of the dye. The(More)
