Good Contrast

A method for in situ preparation of fluorescent AuNPs@AuNCs core/shell nanoparticles by the template of BSA coated gold nanoparticles was developed. The as-prepared AuNPs@AuNCs core/shell nanoparticles possessed advantages such as uniform size, improved monodispersity and excellent fluorescence. The AuNPs@AuNCs core/shell nanoparticles in powder and suspension form were applied to the detection of latent fingermark due to the above properties. The developed latent fingermarks by AuNPs@AuNCs core/shell powder on various surfaces can exhibit excellent ridge details with good contrast between the fingermarks and the substrate. Moreover, under alternative light sources, the latent fingermarks developed with AuNPs@AuNCs core/shell powder work well.

Fe3O4nanoparticle was synthesized in the solution involving water and ethanol. Then,α-Fe2O3shell was produced in situ on the surface of theFe3O4nanoparticle by surface oxidation in molten salts, formingα-Fe2O3/Fe3O4core-shell nanostructure. It was showed that the magnetic properties transformed from ferromagnetism to superparamagnetism after the primaryFe3O4nanoparticles were oxidized. Furthermore, the obtainedα-Fe2O3/Fe3O4core-shell nanoparticles were used to photocatalyse solution of methyl orange, and the results revealed thatα-Fe2O3/Fe3O4nanoparticles were more efficient than the self-preparedα-Fe2O3nanoparticles. At the same time, the photocatalyzer was recyclable by applying an appropriate magnetic field.

Selenium-polypyrrole core–shell nanoparticles are fabricated by an in-situ polymerization process and functionalized with transferrin for targeting and imaging of human cervical cancer cells. The shell thickness and chemical composition of the as-synthesized particles can be manipulated by controlling the precursor concentration. The presence of the polymer layer can greatly increase the thermal stability of the selenium nanoparticles. The presence of transferrin molecules on the surface of the core–shell nanoparticles can significantly enhance their cellular uptake. The tranferrin-conjugated core–shell nanoparticles can be potentially used for the targeting and imaging of cancer cells.
