Replacement of cetyltrimethylammoniumbromide bilayer on gold nanorod by alkanethiol crosslinker for enhanced plasmon resonance sensitivity

Autor: Liang Tang, Meenakshi Venkataramasubramani, Yanyan Wang, Justin Casas

Publikováno v: Biosensors and Bioelectronics. 49:525-530

Surface modification of gold nanorods (GNRs) is often problematic due to tightly packed cetyltrimethylammoniumbromide (CTAB) bilayer. Herein, we performed a double phase transfer ligand exchange to achieve displacement of CTAB on nanorods. During the

Magnetic Nanoparticle Mediated Enhancement of Localized Surface Plasmon Resonance for Ultrasensitive Bioanalytical Assay in Human Blood Plasma

Autor: Meenakshi Venkataramasubramani, Liang Tang, Justin Casas

Publikováno v: Analytical Chemistry. 85:1431-1439

We demonstrate that Fe(3)O(4) magnetic nanoparticle (MNP) can greatly enhance the localized surface plasmon resonance (LSPR) of metal nanoparticle. The high refractive index and molecular weight of the Fe(3)O(4) MNPs make them a powerful enhancer for

Quantification of cardiac biomarkers using label-free and multiplexed gold nanorod bioprobes for myocardial infarction diagnosis

Autor: Justin Casas, Liang Tang

Publikováno v: Biosensorsbioelectronics. 61

Gold nanorod (GNR) is an attractive optical transducer for label-free biosensing owing to the localized surface plasmon resonance (LSPR) which is highly sensitive to the dielectric constant of the surrounding medium modulated by biological bindings.

Synthesis and Characterization of Gold Nanoparticles with Plasmon Absorbance Wavelength Tunable from Visible to Near Infrared Region

Autor: Liang Tang, Weihong Shi, Meenakshi Venkataramasubramani, Justin Casas

Publikováno v: ISRN Nanomaterials.

Gold nanorods with localized surface plasmon resonance (LSPR) can be chemically synthesized. We systematically investigated the effects of reaction parameters and centrifugation on the fine tuning of the rod dimension in scale-up production (80–100

Development of a lateral flow colloidal gold immunoassay strip for the rapid detection of olaquindox residues

Autor: Chunmei Song, Qingtang Liu, Aimin Zhi, Jifei Yang, Yubao Zhi, Qingmei Li, Xiaofei Hu, Ruiguang Deng, Justin Casas, Liang Tang, Gaiping Zhang

Publikováno v: Journal of agricultural and food chemistry. 59(17)

A rapid immunochromatographic lateral flow test strip of competitive format has been developed for the specific determination of olaquindox (OLA) residues in pig urine and muscle tissues. The sensitivity of the test strip was found to be 1.58 ± 0.27
