    • An "on-off-on" electrochemiluminescence aptasensor based on a self-enhanced luminophore for ochratoxin A detection.

    Publication Type: Academic Journal

    Source(s): Analytical and bioanalytical chemistry [Anal Bioanal Chem] 2023 Sep; Vol. 415 (23), pp. 5833-5844. Date of Electronic Publication: 2023 Jul 21.

    Authors:

    Abstract: A highly selective and sensitive "on-off-on" electrochemiluminescence (ECL) aptasensor based on a self-enhanced luminophore was developed for the detection of ochratoxin A (OTA). Specifically, polyethyleneimine functionalized multi-walled carbon nanotu...

    A capillary-based SERS sensor for ultrasensitive and selective detection of Hg 2+ by amalgamation with Au@4-MBA@Ag core-shell nanoparticles.

    Publication Type: Academic Journal

    Source(s): Mikrochimica acta [Mikrochim Acta] 2021 Sep 27; Vol. 188 (10), pp. 354. Date of Electronic Publication: 2021 Sep 27.

    Authors:

    Abstract: A capillary-based SERS sensor was fabricated for ultrasensitive and selective detection of Hg 2+ in water. Au@Ag core-shell NPs embedded with 4-mercaptobenzoic acid (4-MBA) (Au@4-MBA@Ag) were prepared by a seed growth method and fixed on the inner wall...

    Quantification of titanium dioxide nanoparticles in human urine by single-particle ICP-MS.

    Publication Type: Academic Journal

    Source(s): Analytical and bioanalytical chemistry [Anal Bioanal Chem] 2021 Jan; Vol. 413 (1), pp. 171-181. Date of Electronic Publication: 2020 Oct 29.

    Abstract: The increasing use of titanium dioxide nanoparticles in daily use consumer products such as cosmetics, personal care products, food additives, and even medicine has led to growing concerns regarding human safety. It would be ideal to track exposure to ...

    Au nanorod helical superstructures with designed chirality.

    Publication Type: Academic Journal

    Source(s): Journal of the American Chemical Society [J Am Chem Soc] 2015 Jan 14; Vol. 137 (1), pp. 457-62. Date of Electronic Publication: 2014 Dec 29.

    Authors:

    Abstract: A great challenge for nanotechnology is to controllably organize anisotropic nanomaterials into well-defined three-dimensional superstructures with customized properties. Here we successfully constructed anisotropic Au nanorod (AuNR) helical superstruc...
