The paper reports a facile one-pot synthesis of core@shell nanoparticles (NPs) composed of Au core and graphene oxide nanocolloid (GON) shell. Unique properties of Au NPs and GON can be incorporated into a single nanohybrid structure to provide desirable functions for theranosis such as localized surface plasmon resonance, Raman scattering, amphiphilic(More)
The multifunctional DNAzyme (Dz) delivery system is developed based on nano-sized graphene oxide (nGO) for simultaneous detection and knockdown of the target gene. The Dz/nGO complex system allowed convenient monitoring of HCV mRNA in living cells and silencing of the HCV gene expression by Dz-mediated catalytic cleavage concurrently.

Current movie title retrieval models, such as IMDB, mainly focus on utilizing structured or semi-structured data. However, user queries for searching a movie title are often based on the movie plot, rather than its metadata. As a solution to this problem, our movie title retrieval model proposes a new way of elaborately utilizing associative relations(More)
A new framework combining proactive search with mobile hypertext lets mobile phone users avoid text entry and tailors search results to suit the context. Mobile phones and devices are evolving steadily, adding increasingly advanced capabilities. Today's smart phones, for example, have PClike functionality with complete operating system software that(More)
