In this work, we correlated the rational selection of carbon nanoparticles by cancer cells in various stages of the disease to the surface chemistry of the nanoparticles. Understanding the mechanism of interaction of drug carriers with complex cancer cells at different stages of the disease is important. Integration of this knowledge with pathophysiological analysis would promote the development of nanomedicines with superior likelihoods of crossing the endocytic “barrier” for drug delivery.

A new route to fabricating inorganic nanomaterials in protein nanocages is reported, which features encapsulation of a presynthesized nanoparticle (NP) as the seed via self-assembly and subsequent electroless deposition.

We report the fabrication of a novel TaOx-based selector with a trapezoidal band structure, obtained by tuning the concentration of defects in the oxide. Salient features such as a high current density (1 MA·cm–2), high selectivity (5 × 104), low off-state current (~10 pA), robust endurance (>1010), self-compliance, and excellent uniformity were successfully achieved.

We introduce an efficient, controllable, and facile two-step synthetic strategy to prepare graphene-based nanocomposites. A series of reduced graphene oxide nanocomposites incorporating Fe3O4 nanocrystals of various sizes were prepared using the new approach. The capacitance of the as-prepared nanocomposites exhibits a strong dependence on their structure, which indicates that excellent electrochemical properties can be obtained by precisely controlling the microstructure of the electrode materials.

Through the optimization of synthesis and dopant ion concentration, monodispersed, bright up-converting CaF2:Yb3+,Tm3+ nanoparticles were obtained. The new biofunctionalization method enabled the application of this material for labeling and imaging of Candida albicans cells.

Gold nanorings and nanoring arrays with well-defined nanoring quantities, diameters, and spacings were fabricated via colloidal lithography and polymer-assisted Au nanoparticle self-assembly. Three dimensional coaxial gold nanorings and three-dimensional (3D) coaxial gold nanoparticle rings with different diameters were fabricated for the first time.

Poly(vinylidene fluoride-trifluoroethylene)/zinc oxide nanocomposite scaffolds were fabricated by electrospinning. Detailed characterization of the scaffolds showed that they are highly promising candidates for tissue engineering applications as they promote robust cell adhesion and vascularization.

Sulfur-containing, chevron-type graphene nanoribbons were designed and fabricated from sulfur-substituted oligophenylene monomers via a bottom-up synthetic approach. The graphene nanoribbons are composed of distinct segments with varying band gaps that produce a sequence of quantum dots and thus may be useful in nanoscale optoelectronic applications.
