A Graphene Based–Biomimetic Molecularly Imprinted Polyaniline Sensor For Ultrasensitive Detection Of Human Cardiac Troponin T(Ctnt), Meysam Karimi, Mohammad Rabiee, Mohammadreza Tahriri, Reza Salarian, Lobat Tayebi

School of Dentistry Faculty Research and Publications

In the present work, a biomimetic nano-molecularly imprinted polymer (N-MIP) electrode based on a graphene screen-printed electrode was developed for the ultrasensitive detection of cardiac troponin T (cTnT). The biomimetic cavities for targeted sensing for analyte were fabricated by the electropolymerization of conductive co-polymer matrix of aniline and carboxylated aniline on the graphene oxide (GO) electrode, in the presence template protein (cTnT for cardiac troponin T probe) by cyclic voltammetry. The surface characterization of the sensor was performed using cyclic voltammetry (CV) and differential pulse voltammetry (DPV), and scanning electron microscopy (SEM). The best biomimetic surface nanotexture was obtained at …

Significant advances have been achieved in recent years to ameliorate rheumatoid arthritis (RA) in animal models using gene therapy approaches rather than biological treatments. Although biological agents serve as antirheumatic drugs with suppressing proinflammatory cytokine activities, they are usually accompanied by systemic immune suppression resulting from continuous or high systemic dose injections of biological agents. Therefore, gene transfer approaches have opened an interesting perspective to deliver one or multiple genes in a target‐specific or inducible manner for the sustained intra‐articular expression of therapeutic products. Accordingly, many studies have focused on gene transferring methods in animal models by using one of …
