Intolerance to gluten, a protein composite of gliadin and glutenin, present in wheat, barley, and rye and several cereals, can be the causative agent of celiac disease (CD) and other allergic reactions. A gluten-free diet has become essential for people affected by CD, and consequently, the amount of gluten in food products needs to be strictly controlled. In this paper, we report an electrochemical label-free immunosensor for ultrasensitive and specific detection of gliadin. The sensor takes advantage of the specific properties of porous reduced graphene oxide (prGO) covalently functionalized with anti-gliadin antibodies using 1-pyrenecarboxylic acid as linker molecule. Using differential pulse voltammetry (DPV) and [Fe(CN)6](3-/4-) as a redox probe, a decrease of current is linked to the presence of gliadin. The sensor achieved a detection limit of 1.2 ng mL(-1) over a 1.2-34 ng mL(-1) linear range with high selectivity. The advantages offered by this sensor are the possibility to regenerate the surface of the immunosensor, its rapid and ease of production, as well as applicability for the screening of gliadin concentrations in real food samples, as shown here.&lt;/p&gt;</style></abstract><issue><style face="normal" font="default" size="100%">12</style></issue><work-type><style face="normal" font="default" size="100%">Article</style></work-type><custom3><style face="normal" font="default" size="100%">Foreign</style></custom3><custom4><style face="normal" font="default" size="100%">5.711</style></custom4></record><record><source-app name="Biblio" version="7.x">Drupal-Biblio</source-app><ref-type>17</ref-type><contributors><authors><author><style face="normal" font="default" size="100%">Liu, Jing</style></author><author><style face="normal" font="default" size="100%">Xiong, Ranhua</style></author><author><style face="normal" font="default" size="100%">Brans, Toon</style></author><author><style face="normal" font="default" size="100%">Lippens, Saskia</style></author><author><style face="normal" font="default" size="100%">Parthoens, Eef</style></author><author><style face="normal" font="default" size="100%">Zanacchi, Francesca Cella</style></author><author><style face="normal" font="default" size="100%">Magrassi, Raffaella</style></author><author><style face="normal" font="default" size="100%">Singh, Santosh K.</style></author><author><style face="normal" font="default" size="100%">Kurungot, Sreekumar</style></author><author><style face="normal" font="default" size="100%">Szunerits, Sabine</style></author><author><style face="normal" font="default" size="100%">Bove, Hannelore</style></author><author><style face="normal" font="default" size="100%">Ameloot, Marcel</style></author><author><style face="normal" font="default" size="100%">Fraire, Juan C.</style></author><author><style face="normal" font="default" size="100%">Teirlinck, Eline</style></author><author><style face="normal" font="default" size="100%">Samal, Sangram Keshari</style></author><author><style face="normal" font="default" size="100%">De Rycke, Riet</style></author><author><style face="normal" font="default" size="100%">Houthaeve, Gaelle</style></author><author><style face="normal" font="default" size="100%">De Smedt, Stefaan C.</style></author><author><style face="normal" font="default" size="100%">Boukherroub, Rabah</style></author><author><style face="normal" font="default" size="100%">Braeckmans, Kevin</style></author></authors></contributors><titles><title><style face="normal" font="default" size="100%">Repeated photoporation with graphene quantum dots enables homogeneous labeling of live cells with extrinsic markers for fluorescence microscopy</style></title><secondary-title><style face="normal" font="default" size="100%">Light-Science &amp; Applications</style></secondary-title></titles><dates><year><style  face="normal" font="default" size="100%">2018</style></year><pub-dates><date><style  face="normal" font="default" size="100%">AUG</style></date></pub-dates></dates><volume><style face="normal" font="default" size="100%">7</style></volume><pages><style face="normal" font="default" size="100%">47</style></pages><language><style face="normal" font="default" size="100%">eng</style></language><abstract><style face="normal" font="default" size="100%">&lt;p&gt;In the replacement of genetic probes, there is increasing interest in labeling living cells with high-quality extrinsic labels, which avoid over-expression artifacts and are available in a wide spectral range. This calls for a broadly applicable technology that can deliver such labels unambiguously to the cytosol of living cells. Here, we demonstrate that nanoparticle-sensitized photoporation can be used to this end as an emerging intracellular delivery technique. We replace the traditionally used gold nanoparticles with graphene nanoparticles as photothermal sensitizers to permeabilize the cell membrane upon laser irradiation. We demonstrate that the enhanced thermal stability of graphene quantum dots allows the formation of multiple vapor nanobubbles upon irradiation with short laser pulses, allowing the delivery of a variety of extrinsic cell labels efficiently and homogeneously into live cells. We demonstrate high-quality time-lapse imaging with confocal, total internal reflection fluorescence (TIRF), and Airyscan super-resolution microscopy. As the entire procedure is readily compatible with fluorescence (super resolution) microscopy, photoporation with graphene quantum dots has the potential to become the long-awaited generic platform for controlled intracellular delivery of fluorescent labels for live-cell imaging.&lt;/p&gt;</style></abstract><custom3><style face="normal" font="default" size="100%">Foreign</style></custom3><custom4><style face="normal" font="default" size="100%">14.098</style></custom4></record></records></xml>
