Synergetic Effect of Three-in-One Nanocomposite Based on AuNPs and rGO-MWCNTs for Ultrasensitive Electrochemical Bio-Diagnostic Applications
A simple, two-step AuNPs/rGO-MWCNTs nanocomposite fabrication methodology, via drop-casting of rGO-MWCNTs on bare screen printed electrode (SPE) followed by electrodeposition of AuNPs through voltammetric scanning, without using any toxic reducing agents is reported. Each step of the synthesized nanocomposite is characterized using state-of-art spectroscopic and electrochemical methods. Our results demonstrate that the nanostructured AuNPs/rGO-MWCNTs/SPE showed synergistic effects of high electrocatalytic and electron transfer activity, high surface area to volume ratio, that confirms our synthesized material is the best material to fabricate a portable device for rapid, inexpensive, and sensitive electrochemical biosensors. For validation, the fabricated material subjected to electrochemical sensing of BSA protein. Our AuNPs/rGO-MWCNTs nanocomposite exhibited significant and good linear response over 2.5–12.5 μg ml−1 BSA concentration range, with sensitivity of 1.723 μAμg ml−1 and limit of detection (LOD) 0.23 μg/ml. This portable sensing system with enhanced performance demonstrates great potential for our synthesized AuNPs/rGO-MWCNs/SPE nanocomposite in application of point of care applications, and offers a universal and reliable platform for in biomarker detection.

Electrochemical aptasensor using boron-carbon nanorods decorated by nickel nanoparticles for detection of E. coli O157:H7
The development of a label-free impedimetric aptasensor is reported for rapid and sensitive detection of Escherichia coli O157:H7 employing boron-carbon nanorods decorated by nickel nanoparticles (BC-Ni) nanostructured platform. These highly electroactive BC-Ni nanorods were synthesized to increase the sensitivity of the sensor surface and subsequently functionalized with a specific anti-E. coli O157:H7 aptamer (Kd = 69 nM) as bio-recognition moiety. This fully characterized high-affinity DNA aptamer against the bacteria was selected using a facile microtiter plate-based cell-SELEX methodology. The fabricated electrochemical aptasensor is demonstrated to detect E. coli O157:H7 selectively with a detection limit of 10 cfu and a dynamic detection range of 100 to 105 cfu in water, juice, and fecal samples.
