Reduced graphene oxide-polyaniline film as enhanced sensing interface for the detection of loop-mediated-isothermal-amplification products by open circuit potential measurement

Abstract

A novel disposable sensor based on reduced graphene oxide-polyaniline (rGO-PANi) for detection of loop-mediated-isothermal-amplification (LAMP) products.

Electrosynthesis of electrochemically reduced graphene oxide/polyaniline nanowire/silver nanoflower nanocomposite for development of a highly sensitive electrochemical DNA sensor

“…Therefore, this is an effective signal of the transition from GO to ERGO. 29,32 It is clearly seen that in the Raman spectrum of ERGO, Fig. 1B (curve b), the value of I D /I G (1.33) is signicantly higher than that in the Raman spectrum of GO (0.97), Fig.…”

“…The peaks at 1337 cm À1 and 1591 cm À1 are attributed to the typical D and G bands of GO and ERGO, respectively. 29 The D band is associated with defects and disorders of carbon, and the G band is assigned to E 2g mode of sp 2 hybridized carbon relating to the degree of graphitization. 30,31 The increase in the intensity ratio I D /I G exhibits the increase in the number of defects and disorders caused by the removal of functional groups from GO.…”

Human virus detection with graphene-based materials

“…The detection mechanism is based on the pH decrease caused by hydronium ions released during the elongation of DNA in LAMP reaction. Two linear regions were obtained at pH ranging from 6.0 to 7.5 and pH ranging from 7.5 to 9.0 ( Thu et al, 2018 ). LAMP is considered as an advanced genetic technique that can provide extremely fast sequential progression (less than 1 h) and relatively high selectivity (100-fold greater than conventional PCR), because the gene amplification is performed under isothermal conditions within a short diagnostic time by using six gene regions, and one type of enzyme (Bst DNA polymerase).…”

Electrochemical Synthesis of Reduced Graphene Oxide‐Wrapped Polyaniline Nanorods As An Active Nanocomposite For Improved Photocurrent Generation And Photocatalytic And Antibacterial Activities

“…2 (c,d) shows the surface morphology of the ITO/PANI thin lm, which constitutes an interconnected network of PANI nanorods (NRs) represent a well-arranged and orderly uniform polymer chain structure. which makes this network useful for electron transport at the electrolyte-thin lm interface [38][39][40].
