Luminescent glutathione-capped gold nanoclusters (GS-AuNCs) with tunable emissions have been efficiently synthesized by a solution-based microwave method.
Recently, nanoplatforms with multiple functions, such as tumor-targeting drug carriers, MRI, optical imaging, thermal therapy etc., have become popular in the field of cancer research. The present study reports a novel multi-functional liposome for cancer theranostics. A dual targeted drug delivery with radiofrequency…
Biocompatible and enzyme-responsive supramolecular assemblies have attracted more and more interest in biomaterial fields, and find many feasible applications especially in the controlled drug release at specific sites where the target enzyme is located. In this work, novel supramolecular nanoparticles were successful…
Conducting polyaniline is deposited into a G-quadruplex-crosslinked pNIPAM copolymer undergoing switchable stimuli-responsive solution/hydrogel/solid transitions.
Hierarchical chiroptical activity of emissive YVO 4 :Eu 3+ nanoparticles in chiral nematic cellulose host matrix.
Porous Co 3 O 4 -MOF and Ru/Co 3 O 4 -MOF were prepared and applied in the catalytic oxidation of toluene. Ru/Co 3 O 4 -MOF showed higher catalytic performance than other materials. The stability and water-resistence of the catalyst were also studied.
We take advantage of the folic acid conjugated iron-based metal–organic frameworks (Fe-MIL-101) without any surface modification to design a simple and sensitive colorimetric assay to detect cancer cells based on its intrinsic peroxidase-like activity over broad pH range.
Halogenated silicene, with enhanced stability compared with silicene, presents a moderate and tunable direct gap with small carrier effective mass and improved elastic properties.
Electronic properties of the hetero-structures consisting of silicene, graphene and BN monolayers under the influence of an electric field were investigated using density functional theory. With no electric field, both silicene/graphene and silicene/BN were shown to have a finite gap of about ∼50 meV, though silicene…
The nature of the promotion effect of isolated potassium atoms anchored on surfaces of a Hollandite manganese oxide was investigated by studying their geometric and electronic structures. The results reveal that the surface isolated potassium atoms with hybridized d-sp orbitals specifically promote oxygen activation,…
Two different precursors, manganese nitrate (MN) and manganese acetate (MA), were employed to prepare two series of catalysts, i.e., xCuyMn(N)/TiO2 and xCuyMn(A)/TiO2, by a co-impregnation method. The catalysts were characterized by XRD, LRS, CO-TPR, XPS and EPR spectroscopy. The results suggest that: (1) both xCuyMn(…
Ca 8 MgTb(PO 4 ) 7 :Eu 3+ phosphor, a potential candidate for application in NUV-based WLEDs, can show efficient energy transfer from Tb 3+ to Eu 3+ , color-tunable emission from green to pure red and excellent thermal stability.
Carbon-based nanoparticles (CNPs) have emerged as novel man-made materials with diverse applications, which may present significant risks to organisms. To bridge the gap in our knowledge of nanotoxicology, a number of in vitro or in vivo studies have been carried out. However, toxicity data remains limited. Herein, we…
This work presents the design of substrates for Surface Enhanced Raman Scattering (SERS) using star-like gold nanoparticles which were synthesized using a wet chemical method and functionalized with 1-dodecanethiol. This molecule allowed us to obtain a spacing of ∼2.6 nm among gold stars, which promoted the generation…
Azobenzene photoresponsive elements can be installed on sulfonylureas, yielding optical control over pancreatic beta cell function and insulin release. An obstacle to such photopharmacological approaches remains the use of ultraviolet-blue illumination. Herein, we synthesize and test a novel yellow light-activated sul…
Bioreducible FA-PEG- b -P(α-Pt( ii )-SS-CL/CL) conjugates have been successfully developed in order to build redox-responsive micelles with targeting and site-specific drug releasing abilities.
How to concentrate target molecules on the surface of a SERS substrate is a key problem in the practical application of SERS. Herein, we designed for the first time a pollutant capturing surface enhanced Raman spectroscopy (SERS) substrate, namely porous BN microfibers uniformly decorated with Ag nanoparticles, in whi…
The upconversion luminescence properties of oleic acid capped NaYF 4 :Gd 3+ :Yb 3+ :Er 3+ upconversion nanoparticles (UCNP) with pure β crystal phase and Nd 3+ ions as an additional sensitizer were studied in the temperature range of 288 K < T < 328 K.
The in-plane (kip) and through-plane (ktp) thermal conductivities of heat sinks using carbon nanotubes (CNTs), graphene nanosheets (GNs), and CNT/GN composites are extracted from two experimental setups within the 323-373 K temperature range. Hierarchical three-dimensional CNT/GN frameworks display higher kip and ktp…
The RGO sheets are homogeneously distributed in the RGO/Cu composite produced by the molecular-level mixing and high-shear mixing method and the composites with high mechanical properties are obtained.
