【RSC Adv】Controlled evaporative self-assembly of Fe3O4 nanoparticles assisted by an external magnetic field
High fidelity and regularity structures of nanoscale materials has opened up new opportunities for developing miniaturized devices. A simple yet robust approach of magnetic field assisted controlled evaporative self-assembly (CESA) is developed to achieve Fe3O4 nanoparticle (NP) micro- and nano-patterns in a two dimensional (2D) direction. In the magnetic field assisted CESA process, the self-asse...

【RSC Adv.】Close-packed assemblies of discrete tiny silver nanoparticles on triangular gold nanoplates as a high performance SERS probe
Bimetallic nanocatalysts often display enhanced physical and chemical properties compared to those of their monometallic counterparts. Herein, we introduce a simple method to fabricate an island like array of tiny Ag nanoparticles bounded on triangular Au nanoplates as the surface-enhanced Raman scattering (SERS) substrate. The surface morphology of the synthesized nanoparticles was characterized ...

【RSC Adv】Concave gold nanoparticle-based highly sensitive electrochemical IgG immunobiosensor for the detection of antibody-antigen interactions
In this work, we report a novel electrochemical sensor for the label-free, real time and highly sensitive detection of antibody-antigen interactions based on concave gold nanocuboids (CAuNCs). In contrast to low-index facet gold nanoparticles (AuNPs) such as gold nanorods (AuNRs), the CAuNCs provide higher surface atoms with enhanced chemical activities, which can efficiently catalyse the oxidatio...

【RSC Adv】Fabricating a morphology tunable patterned bio-inspired polydopamine film directly via microcontact printing
A robust and simple strategy of microcontact printing is provided to fabricate micro-patterned polydopamine (PDA) films with tunable morphology achieved by altering the concentration of PDA "ink" solution. Photoactive sites on the surface of patterned PDA films allow the further growth of polymer brushes by self-initiated photografting and photopolymerization (SIPGP) endowing the bio-inspired PDA ...

【RSC Adv】A remarkable sensitivity enhancement in a gold nanoparticle-based lateral flow immunoassay for the detection of Escherichia coli O157:H7
Because of the distinctive features of ease-of-use, low cost and portable detection, a gold nanoparticle (AuNP) based lateral flow immunoassay (LFA) is an effective and currently used method for the detection of Escherichia coli O157:H7; however, its low sensitivity limits its practical use. In the present study, the size and uniformity of AuNPs have been systematically optimized to maximally ampl...

【RSC Adv.】Au nanoparticle-loaded PDMAEMA brush grafted graphene oxide hybrid systems for thermally smart catalysis
A novel smart catalytic system was successfully constructed by using poly[(dimethylamino)ethyl methacrylate] (PDMAEMA) brush grafted graphene oxide (GO) to load gold nanoparticles (Au NPs). The catalytic activity of the Au NPs was finely tuned by temperature, which can control the inclusion and ''''''''exposure'''''''' of Au NPs inside the PDMAEMA brushes via the phase transition of the grafted PD...

[Adv. Synth. Catal.] Copper-Nitrene Triggered Annulation of α-Acyl Cinnamides: Access to Isoxazol-3(2H)-ones
A facile and efficient one-pot synthesis of isoxazol-3(2H)-ones has been developed starting from α-acyl cinnamides and tosyliminophenyliodinane catalyzed by copper(II) acetate [Cu(OAc)2] under very mild conditions involving a tandem aza-Michael addition and intramolecular cyclization sequence.

【RSC Adv】Effect of Polyethylene Glycol on the Antibacterial Properties of Polyurethane/Carbon Nanotube Electrospun Nanofibers
The discovery of antibacterial functions for carbon nanotube (CNT) has triggered great interest of people, because of excellent antibacterial property of CNT. However, there are two obstacles, i.e., cell toxicity and CNT’s aggregation in polymer matrix, which would greatly limit the antibacterial application of CNT in medical device. In this article, a facile, cost-effective, time-saving and envi...

[2015][RSC Adv., 2015,5: 6815-6822]Colorless Metallodithiolene Oligomers and Polymers with Intense Near- and Mid-Infrared Absorption
Reported herein are the syntheses and properties of a series of multi-nuclear metallodithiolene complex oligomers (5, 6 and 7) and a homologous polymer (8). The Ni/Pd–dithiolene complexes 5, 6 and 7 are characterized by intense absorption in the spectral region of 1000–1800 nm with a high molar absorption coefficient(e.g.,105M-1cm-1 at 1257 nm for 7). Complex polymer 8 is readily soluble in co...
