Ultrasensitive Immunosensor Based on Langmuir-Blodgett Deposited Ordered Graphene Assemblies for Dengue Detection.

In this manuscript partially reduced graphene oxide (RGO) nanosheet-based electrodes have been utilized for quantification of the NS1 protein and subsequently for dengue detection. NS1 is the biomarker found circulating in the body of dengue-infected persons on or after first day of the appearance of disease symptoms. Graphene oxide (GO) has been synthesized using a modified Hummer's method, and its ordered nanostructured films have been electrophoretically deposited on indium tin oxide (ITO)-coated glass substrates using Langmuir-Blodgett (LB) deposition.

Highly efficient Polyaniline-MoS hybrid nanostructures based biosensor for cancer biomarker detection.

In this work, polyaniline nanospindles have been synthesized using iron oxide as sacrificial template. These nanospindles were utilized for the fabrication of PANI-MoS nanoflower architectures via hydrothermal route. The electrostatic interaction between PANI and MoS improves the conductivity and provides more direct paths for charge transportation.

Electrochemical genosensor based on template assisted synthesized polyaniline nanotubes for chronic myelogenous leukemia detection.

This work reports a facile approach to synthesize polyaniline nanotubes (PANI-NT) by using manganese oxide as sacrificial templates. This template assisted polyaniline nanotubes (t-PANI-NT) were utilized as electrode material after deposition onto the indium tin oxide (ITO) coated glass substrates by using the electrophoretic technique. The structural, morphological and electrochemical characterizations of the t-PANI-NT show relatively better results compared to chemically synthesized PANI-NT (c-PANI-NT).

Langmuir-Blodgett Nanoassemblies of the MoS-Au Composite at the Air-Water Interface for Dengue Detection.

We report Langmuir-Blodgett (LB) films of molybdenum disulphide (MoS) and gold nanoparticles (AuNP) composite being utilized as a biosensing platform for dengue detection. The LB films of the MoS-AuNP composite have been transferred from the air-water interface to the indium tin oxide-coated glass substrate under optimized conditions. Further, antibodies specific to dengue NS1 antigen were immobilized onto these LB films.
