Development of aptamer-conjugated magnetic graphene/gold nanoparticle hybrid nanocomposites for specific enrichment and rapid analysis of thrombin by MALDI-TOF MS.

Ya Xiong et al.

Talanta, 129, 282-289 (2014-08-17)

Simple, rapid and sensitive analysis of thrombin (a tumor biomarker) in complex samples is quite clinical relevant and essential for the development of disease diagnosis and pharmacotherapy. Herein, we developed a novel method based on aptamer-conjugated magnetic graphene/gold nanoparticles nanocomposites

Mimetic biomembrane-AuNPs-graphene hybrid as matrix for enzyme immobilization and bioelectrocatalysis study.

Tianshu Wang et al.

Talanta, 143, 438-441 (2015-06-17)

A hybrid composite constructed of phospholipids bilayer membrane, gold nanoparticles and graphene was prepared and used as matrices for microperoxidase-11 (MP11) immobilization. The direct electrochemistry and corresponding bioelectrocatalysis of the enzyme electrode was further investigated. Phospholipid bilayer membrane protected gold

Multilevel and Multicomponent Layer-by-Layer Assembly for the Fabrication of Nanofibrillar Films.

Yuanyuan Zhang et al.

ACS nano, 9(7), 7124-7132 (2015-07-15)

In this study, we demonstrate multilevel and multicomponent layer-by-layer (LbL) assembly as a convenient and generally applicable method for the fabrication of nanofibrillar films by exploiting the dynamic nature of polymeric complexes. The alternate deposition of poly(allylamine hydrochloride)-methyl red (PAH-MR)

Silica-based strong anion exchange media for protein purification.

Feng Gu et al.

Journal of chromatography. A, 1376, 53-63 (2014-12-30)

The main objective of our research was to develop silica-based, polymer-functionalized ion exchange materials for single-use bioprocess applications, with the ultimate goal of achieving maximal binding capacity for target proteins. Herein we report the utilization of Grace(®) wide pore silica

Role of 5-aminolevulinic acid-conjugated gold nanoparticles for photodynamic therapy of cancer.

Zhenxi Zhang et al.

Journal of biomedical optics, 20(5), 51043-51043 (2015-05-30)

There are three possible mechanisms for 5-aminolevulinic acid (5-ALA) conjugated gold nanoparticles (GNPs) through electrostatic bonding for photodynamic therapy (PDT) of cancer: GNPs delivery function,singlet oxygen generation (SOG) by GNPs irradiated by light, and surface resonance enhancement (SRE) of SOG.

Construction and biofunctional evaluation of electrospun vascular graft loaded with selenocystamine for in situ catalytic generation of nitric oxide.

Siyuan Chen et al.

Materials science & engineering. C, Materials for biological applications, 45, 491-496 (2014-12-11)

Construction and biofunctional evaluation of a novel vascular graft with in situ catalytic generation of nitric oxide were described in this paper. Poly α-lysine and poly (γ-glutamic acid) were deposited alternately onto the surface of an electrospun poly ε-caprolactone matrix

Polyethyleneimine-grafted collagen fiber as a carrier for cell immobilization.

Deyi Zhu et al.

Journal of industrial microbiology & biotechnology, 42(2), 189-196 (2014-12-30)

Collagen fiber (CF), an abundant natural biopolymer, features many favorable properties that make it a potential carrier for cell immobilization. In the present investigation, CF was grafted with polyethyleneimine (PEI) using glutaraldehyde (GA) as the cross-linking agent, resulting in the

Multiplexed electrochemical immunoassay using streptavidin/nanogold/carbon nanohorn as a signal tag to induce silver deposition.

Changrong Zhao et al.

Analytica chimica acta, 847, 37-43 (2014-09-30)

An ultrasensitive multiplexed immunoassay method was developed by using streptavidin/nanogold/carbon nanohorn (SA/Au/CNH) as a novel signal tag to induce silver enhancement for signal amplification. The Au/CNH was prepared by in situ growth of nanogold on carboxylated CNH and functionalized with
